1 INTRODUCTION

1.1 MBTA HISTORY AND OVERVIEW The Massachusetts Bay Transportation Authority (MBTA), often refereed to as “The T”, is a body politic and corporate, and a political subdivision of the Commonwealth of Massachusetts formed in 1964 to finance and operate bus, subway, commuter rail and ferry systems in the greater Boston, Massachusetts, area. The MBTA General Manager is the administrator of rail and transit for MassDOT. A third party contractor, currently the Massachusetts Bay Commuter Railroad Company (a joint venture of Bombardier, Veolia Transportation, formerly Connex North America, and Alternate Concepts), operates and maintains the MBTA’s Commuter Rail Service. The MBTA's Commuter Rail system is the fifth-busiest commuter rail in the country, after only New York and Chicago area systems. The lines go as far south as Providence, Rhode Island, and as far north as Newburyport. And they run as far west as Worcester, and Fitchburg Massachusetts. The trains have two terminal stops in Boston (South Station and North Station). Both transportation hubs offer connections to Amtrak, local bus and subway lines. Figure 1-1 shows the composite MBTA Commuter Rail System Map.

1.3 GEOGRAPHIC OVERVIEW

1.3.1 North Side: North Station Lines

1.3.1.1 Eastern Route (Newburyport/Rockport Line) The MBTA owns and operates the Eastern Route. This branch runs northeast from North Station to Newburyport and Rockport. The main line runs from North Station through Newburyport for 34.9 miles and makes stops at 11 stations. The Gloucester branch splits from the main line at Beverly Depot station and runs east till Rockport, covering 16.8 miles and 8 stations along the segment. This route serves MBTA's commuter rail traffic, with an approximate weekly ridership of 18,023.

1.3.1.2 Western Route (Haverhill Line) The Western Route runs straight north from North Station to Haverhill, serving 14 stations along the route. A station stop also exists at Oak Grove in Malden, but this stop is only used when the Orange Line rapid transit service is disrupted. The approximate length of the route is 32.1 miles. Owned by MBTA, this branch serves MBTA commuter rail traffic, with approximately 10,457 passengers commuting weekly. This line is connected to the New Hampshire Route via the Wildcat Branch.

Section 1: Introduction August, 2012 Page 1-6 PTC Implementation Plan

MBTA Revision 4

1.3.1.3 New Hampshire Route (Lowell Line) The New Hampshire Route runs north-west from North Station to Lowell, Massachusetts. This line is owned and operated by MBTA and approximately serves a weekly ridership of 12,569 commuter rail passengers, for 9 stations along the route. The approximate length of the New Hampshire Route is 24.5 miles. This line is connected to the Western Route by the Wildcat Branch.

1.3.1.4 Wildcat Branch The Wildcat Branch is a single-track branch line which connects the New Hampshire Route at Wilmington Station to the Western Route at Wilmington Junction. The approximate length of the branch line between the connecting stations is 3 miles. This line is primarily used for passenger service by both the Amtrak Downeaster service from Boston to Portland, Maine, as well as the MBTA commuter rail for certain rush-hour Haverhill trains. The branch also carries some freight service by Pan Am Railroads.

1.3.1.5 Fitchburg Route The Fitchburg Route runs west from Boston’s North Station to Fitchburg, Massachusetts. This Line is the longest line in the system in terms of both length and travel time. It draws about 10,000 weekly riders for MBTA's commuter rail service, spanning across 17 stations and approximately 48.8 miles of track length. In 2009, the US Department of Transportation proposed the extension of the line from Fitchburg to include a new terminus. There is also a plan to upgrade the Fitchburg Line to have cab signaling.

1.3.2 South Side: South Station Lines

1.3.2.1 Framingham/Worcester Line The Framingham/Worcester Line runs west from South Station to Worcester, Massachusetts, though some trains terminate at Framingham, Massachusetts. From Boston to Framingham, this line is owned, maintained and operated by the MBTA. From Framingham to Worcester, the line is owned and operated by CSX. It is not PTC equipped. The line is partially cab signal equipped. The cab signaling extends from CP 21 (Framingham) to CP 44 (Worcester). The length of this branch is around 44.3 miles. It serves an average weekly ridership of 17,600 passengers and stops at 17 stations. In 2009, the Commonwealth of Massachusetts completed an agreement to purchase the tracks from Framingham to Worcester, with the actual transfer expected in 2011. Earlier phases of the agreement had allowed the addition of five weekday trains to Worcester.

1.3.2.2 Needham Branch The Needham Branch Service runs from South Station to Needham, Massachusetts. This branch extends off the Southwest Corridor just west of Ruggles Station. Owned and operated by MBTA for its commuter rail service, this branch operates weekdays and Saturdays and serves a weekly ridership of 7,604 passengers. It spans across 9.3 miles, making stops at 11 stations. This branch is not cab signal equipped.

1.3.2.3 Franklin Branch The Franklin Branch of MBTA Commuter Rail travels in a northeasterly direction toward Boston, Massachusetts from Franklin, Massachusetts. The branch extends from Forge Park Station to South Station and serves approximately 13,000 passengers on a weekly basis. This branch spans across 27.4 miles making stops at 16 stations along the route. This branch is not cab signal equipped. The Franklin Branch was later extended to Forge Park/495 but the MBTA decided to keep the name of the line the same. The line is sometimes referred as the Franklin/Forge Park Line.

1.3.2.4 Attleboro/ Providence Main Line The Providence /Attleboro Main Line runs southwest from Boston, Massachusetts. This line carries service between South Station and Providence, Rhode Island. A part of this branch splits into Stoughton branch, which is operated solely by the MBTA. Within Massachusetts, this line is owned by MBTA. Beyond the state line of Massachusetts, in Rhode Island this line is owned and operated by Amtrak for its Northeast Corridor Rail service. ATC / ACSES II is operational on the main branch. This main line serves an average weekly ridership of 19,181 passengers over 11 stations along the route and measures 42 miles in length. As part of the South County Commuter Rail initiative, a 20- mile extension is under construction past Providence to T. F. Green Airport and Wickford Junction in Rhode Island.

1.3.2.5 Stoughton Branch The Stoughton Branch splits at the Canton Junction from the Attleboro / Providence Main Line and runs for two stations to Stoughton, Massachusetts. This branch serves MBTA's commuter rail traffic of around 8,682 passengers weekly and measures 4.6 miles.

1.3.2.6 Dorchester Branch (Fairmount Line) The Dorchester Branch (or Fairmount Line), except for a short portion in Milton, lies entirely within Boston, and runs in the southwest direction from South Station to Readville. Most trains reverse direction at the south end at Readville. The Fairmount Line has 5 stations and approximately spans across 9.2 miles, serving an average of 1,843 passengers weekly on MBTA's commuter rail service.

1.3.2.7 Old Colony Lines The Old Colony Lines are branches of the MBTA Commuter Rail system, connecting downtown Boston, Massachusetts with the South and Southeast. The Old Colony Lines are split into four segments – Middleboro Main Line, Greenbush, Plymouth Branch and Kingston Branch. The Middleboro Main Line segment runs south from South Station to Middleboro / Lakeville. This segment serves 9,700 weekly riders and stops at 10 stations along the 35-mile segment stretch. The Greenbush Branch runs east and then turns south along the shoreline, from South Station to Scituate, Massachusetts, serving a weekly average ridership of 4,500 passengers over 10 stations and 17.3 miles. The Kingston and

Section 1: Introduction August, 2012 Page 1-8 PTC Implementation Plan

MBTA Revision 4

Plymouth Branch segments turn southeast from Braintree Station and serve 7 stations, with an average weekly traffic of 10,350 passengers.

1.4 EXISTING SYSTEM OVERVIEW The MBTA Commuter operation is divided into two major subdivisions, South and North. All lines heading north of Boston originate from the North Station. All lines heading south of the city originate from the South Station. The line ownership map and the trackage rights map are displayed in Figure 1-4 and Figure 1-5 respectively. The MBTA operation is governed by the MBTA Operating Rules, and Employee Timetables (Refer to Section 14). The General Orders are issues from time to time, which can modify the other governing rules. The Maximum Authorized Speeds (MAS) and Permanent Speed Restrictions (PSR) are listed in Employee Timetables. Temporary Speed Restrictions (TSR) are conveyed to Train Crews by Train Order or General Notice. Normally there are Temporary Signs provided in the field associated with TSR. The type of signals and train control systems on each of the mainline tracks and interlocking, are listed in Employee Timetables.

1.5 EXISTING SIGNAL SYSTEM The MBTA signaling systems consist of Automatic Block Signaling (ABS) with and without Cab Signaling/Automatic Train Control system. The existing landline and microwave communication systems support the signal systems. In the southern division with the exception of half of the Framingham/Worcester Line and Needham Line and Franklin Line, all are Cab Signal equipped and operate under ATC rules. The Shore Line which is part of the subdivision is also ACSES II equipped. Currently, this is the only line in full compliance with FRA PTC requirements. On the North Side, the existing train control system consists of the ABS without ATC. The MBTA back office supports all the North Side lines. All lines north and south have wayside signals for traffic control. All MBTA vehicles are FRA compliant ATC and ACSES II equipped and in full compliance with NORAC time table requirements with the exception of the Bombardier Cab Control Coaches. The Bombardier Cab Control Coaches are equipped with ATC but have not been equipped with ACSES II to date.

Automatic Speed Control (ASC) territory which 562 consists of continuous cab signaling and speed control enforcement of the cab signal speed. Protection is provided by the signal system for both the following and opposing movements.

1.6 EXISTING WAYSIDE COMMUNICATIONS INFRASTRUCTURE MBTA’s right-of-way employs a mix of fiber optics, copper (electrical) and wireless communications plant infrastructure (backhaul) to transport information throughout the MBTA property, and primarily to the North Side and South Side control centers (back office). The North Side and South Side control centers are linked via a fiber optic link. Some locations employ multiple communication methods to transfer information to specific locations or onto a network. Concerning PTC implementation and installation, the existing system-wide communications infrastructure will be used to the greatest extent possible. Optical, electrical and microwave methods will be analyzed and discussed to realize reliable transmission of the PTC data. Existing wireless structures, and possibly others, along the right-of-way (ROW) maybe used to mount PTC system antennas and associated equipment. Appendix section 14.6 Tables 14.3, 14.4 and 14.5 document the MBTA’s existing communications infrastructure.

1.6.1 Wireless For North and South Lines, 900MHz radios are used for data communications and 160MHz radios are used primarily for voice communications. Microwave links are employed throughout MBTA’s property too, as higher rate/bandwidth communication links.

1.6.2 Hard Lines Various owned and leased electrical and optical communications topologies, bandwidths and terminal equipment exist on MBTA’s property.

3 TECHNOLOGY

3.1 GENERAL The Massachusetts Bay Transportation Authority (MBTA) Positive Train Control (PTC) system will consist of an existing Cab Signaling System (CSS) with Automatic Train Control System (ATC) supplemented by the addition of the latest revision to the vital microprocessor based Advanced Civil Speed Enforcement System II (ACSES II). The continuous CSS ATC system will continue to provide train separation and signal speed enforcement functions in signaled territory, and will operate in conjunction with the added functions that are provided by ACSES II. For the interoperability requirement, MBTA will have an I-ETMS compatible back office server, which will operate in parallel with the ACSES II safety server. Similarly, all WIUs will be dual equipped to broadcast I-ETMS compatible messages along with ACSES II messages. This is further explained in Section 5 of this document. However, any functional variances between the Type-Approved I-ETMS and the system implemented by MBTA for interoperability will be addressed in a PTC Development Plan (PTCDP) submitted by MBTA. Shore Line South is equipped and functioning with an ACSES II system, and is fully FRA PTC compliant. Remaining lines are operating with ABS either with or without ATC. These lines will be upgraded with ACSES II functionality. Since the existing signaling systems are FRA compliant, the details are not included in this document. The PTC functionality will be added as an overlay onto the existing signaling system. The MBTA PTC system will provide enforcement of Permanent Speed Restrictions (PSR) (curves, bridges etc.) and Temporary Speed Restrictions (TSRs), slow orders, in five mile per hour (MPH) increments, as well as enforcement of stop signal aspects at interlocking home signals in conjunction with all existing onboard CSS equipment. The following sections describe the functionality and hardware of the ACSES II technology elements comprising the MBTA PTC system, and how it interacts with the CSS/ATC system to enforce positive train stop (PTS) where required. These technology elements include Wayside, Office, Communications, and onboard equipment.

3.2 ACSES II FUNCTIONALITY MBTA will apply the ACSES II technology and functionality as implemented by Amtrak and approved by FRA as type acceptance.

3.2.1 Permanent Speed Restrictions The MBTA PTC system will enforce Permanent Speed Restrictions (PSR). Strategically installed wayside transponders will be encoded with site-specific track profiles and associated authorized permanent speed limits. When the train moves along the tracks, it will receive the encoded message from the transponder. The train’s on-board computer (OBC) will calculate the speed profile from the data received and the current train speed. The OBC will also apply the braking algorithm to generate braking and penalty curves and issue a warning signal if the train exceeds the required speed. If the train operator ignores the warning signal and fails to enforce the braking curve, the OBC will automatically enforce the penalty curve.

3.2.2 Temporary Speed Restriction The MBTA PTC system will enforce Temporary Speed Restrictions (TSR). The TSR data will be communicated to the Train OBC via the data radio network. Trains

Section 3: Technology August, 2012 Page 3-2 PTC Implementation Plan

MBTA Revision 4

approaching the interlocking will request TSR data. In the field, this request will be routed via Base Communication Package (BCP) to the back office TSR server. The TSR server will respond by sending all the TSR data covered by the local BCP plus the next two BCP stations. The OBC will enforce the TSR in the same manner as it will handle the PSR. If there is a PSR and TSR within the same location, OBC will enforce the lower of the two speeds.

3.2.3 Positive Train Stop The MBTA PTC system will enforce a stop at every home signal displaying a Stop aspect. The transponder located at the distant signal will provide the information to the OBC that the train is approaching a home signal and the distance to the home signal. The OBC will use this data to generate a stop profile to be at zero speed just before the home signal as defined in the employee timetable. If the train violates the stop profile, the OBC sends a request to the ATC system to stop the train. If the ATC system receives an aspect more permissive than Restricting, it overrides the stop request. If the ATC receives a Restricting aspect the stop is enforced. In the event the ATC is cut-out or failed in route, ACSES II will enforce the stop at home signals. Once the train has stopped at the required home signal, it will be held until one of the following conditions is met:  The ATC system receives an aspect more permissive than Restricting.  The train operator pushes a Stop Bypass Button. This action requires prior verbal authorization from the train dispatcher.  The Stop request is removed by train dispatcher via data radio.

3.2.4 Application of PTC in ABS territory without ATC The MBTA ACSES II implementation in ABS territories without ATC will be in compliance with 49 CFR Part 236 subpart I. ACSES II will be applied here without any material modification to the already approved ACSES II which is in revenue service now. However, any functional variances between the Type-Approved ACSES II and the system implemented by MBTA for ABS territory without conventional track circuit based ATC is briefly explained in the NPI. Any of these variances will be fully addressed in a PTC Development Plan (PTCDP) submitted by the MBTA. The PTCDP will be submitted per the FRA mandated timeline. In the ABS territories without ATC, WIUs will be installed at every Automatic signal location intermediately between the interlockings. These WIUs will be programmed in the same manner as if being installed at the normal interlocking. The BCPs associated with these WIUs will transmit the radio release for a more permissive signal than Stop and Proceed. Stop and Proceed indication will be enforced as a positive stop enforcement similar to that which is being implemented for interlocking home signals. The differences in the application of ACSES II in ABS territories will be in the data description and not in the software modification. Refer to the MBTA PTCDP for further operational detail and clarification.

3.3 PTC OFFICE SYSTEM

3.3.1 Office Safety TSR Server Sub-System The MBTA PTC office system features a Safety TSR Server (STSR) subsystem that is completely autonomous from the existing CTC office system. For MBTA Territory, two separate Safety TSR Servers will be provided: one located at the North Side Control Center and another at the South Side Control Center. Each control center will have view- only capabilities of the other. Tenant railroads operating in the MBTA territory will receive TSR information directly from MBTA STSR. Refer to Figure 3-2 for an overview of the sub-systems comprising the PTC Office system. Figure 3-2 – PTC Office System

3.3.2 Office Safety TSR Subsystem Elements The Safety TSR Server subsystem is composed of the following major components:  Vital Safety TSR Servers

Section 3: Technology August, 2012 Page 3-4 PTC Implementation Plan

MBTA Revision 4

 Rail Traffic Controller (RTC) User Interface Workstations  Maintenance workstation  Network interfaces  Printers

3.4 VITAL SAFETY TSR SERVERS The Vital Safety TSR servers will be single servers or server clusters at the North Side and South Side control centers. TSR servers will execute the vital TSR function in accordance with the requirements of 49 CFR Part 236. The servers will be required to exhibit very high function availability, commensurate with the safety critical nature of the TSR functionality and the operational demands of the railroad. User interface to the servers will be through non-vital user interface workstations. The servers will be located in secure computer facilities at both control centers. Vitality of the Safety Server functions implemented in non-vital hardware and software will be assured utilizing any of the following industry accepted safety assurance concepts:  N-version programming  Checked-redundant  Diversity and self-checking. Vitality of the data transmitted from the STSRs to trains will be independent of the physical data communication transport systems consisting of MBTA backhaul system and the PTC Data Radio system (see Wayside systems). Vital and error-detecting communications will be ensured via appropriate Cyclical Redundancy Check techniques. Safety verification will be in accordance with 49 CFR Part 236, Appendix C. Each server (or server cluster) at both control centers will independently provide for safety assurance of its database and safe execution of its program. Safety TSR servers will be powered by conditioned power from the Control Center Uninterruptible Power Supply (UPS) with backup emergency generators. An Emergency Management plan will be implemented to assure high availability of the TSR function. Each server at both control centers will have an individual backup, in the event of a failure.

3.5 RTC USER INTERFACE WORKSTATIONS RTC User Interface workstations will be furnished for all RTC user interaction functions. The RTC workstations will be Commercial Off-the-Shelf (COTS) products running a COTS operating system and MBTA PTC user interface application. Each RTC User Interface workstation will include:  COTS PC

Section 3: Technology August, 2012 Page 3-5 PTC Implementation Plan

MBTA Revision 4

 Liquid Crystal Display (LCD) monitor  Keyboard  Mouse

3.6 MAINTENANCE WORKSTATIONS Each Safety TSR Server will include a maintenance workstation for programming development, configuration and system administrator interaction with the Safety TSR server. Each maintenance workstation will include:  COTS PC or use of the Safety Server depending on vendor configuration  LCD monitor  Keyboard  Mouse

3.7 PTC OFFICE NETWORK A secure, high availability Local Area Network (LAN) will interconnect the elements of the PTC office system and provide a gateway to the MBTA Wayside Communications Network and to the PTC system in the field. The LAN will consist of managed switches, routers and other devices that will be completely isolated from the outside world without connection to the Internet, and shall be physically confined to the North Side and South Side control centers. Firewalls and other intrusion detection methods will be utilized to ensure that only authorized message traffic traverses the LAN. The PTC office network will be completely isolated from the CTC office network.

3.7.1 Safety TSR Server Implementation The Safety TSR (STSR) subsystem will be commissioned along with the initially deployed PTC segment. The server(s) will undergo rigorous pre-commissioning safety verification to ensure that all its data are accurate.

3.8 COMMUNICATIONS SUB-SYSTEMS The communications system required to support the MBTA PTC System is divided into the following two subsystems:  Data Radio Communications System – Connects the wayside system elements to the onboard system elements.  Backhaul Communications System – Connects the TSR Server to locations housing wayside system elements.

3.8.1 Data Radio Communications System The data radio communications system is a functional message conduit for the MBTA PTC System. The integrity of the data transmission is not dependent on the data radio communications technology since the safety-critical application layer is independent

Section 3: Technology August, 2012 Page 3-6 PTC Implementation Plan

MBTA Revision 4

from the non-vital communication application layers. Additional checks are performed onboard to ensure protection from duplicate messages, against data storage errors and against communication message routing errors in the non-vital communications system. The PTC/ACSES II message data structure shall be the same with either 220 or 900 MHz radio transmission. The major components of the onboard data radio system, generically referred to as a Mobile Communications Package (MCP) include:  Antenna(s);  Radio Frequency (RF) transmission cable such as coaxial cable, equipped with surge protection;  Mobile data radio, consisting of an RF transceiver and a data controller;  Communications Controller – (existing as part of ACSES II) Used if multiple technologies are employed, interfaces MCP to other onboard PTC elements;  Power Unit – (existing as part of ACSES II) adapts onboard power system to that required by onboard data radio system elements, equipped with spike filter/surge protection. Data radio system installations at wayside locations generically referred to as a Base Communications Package (BCP), will include the following elements:  Antenna(s);  Antenna support structure such as a pole or tower, with earth grounding;  RF transmission cable such as coaxial cable, equipped with surge protection;  RF transmission components such as duplexers, combiners, and multi-couplers, as required;  Equipment housing, such as a weatherproof case or enclosure;  Base station data radio consisting of a radio transceiver and a data controller;  Communications Controller – Used if multiple technologies are employed, interfaces BCPs to other wayside PTC elements;  Power Unit – adapts wayside power system to that required by wayside data radio system elements, equipped with surge protection; Both BCPs and MCPs shall be solid state, programmable units. The MCPs shall be Association of American Railroads (AAR) compliant for onboard environment, and the MCPs shall be installed in shelters/enclosures with appropriate environmental treatment. Each interlocking will require a data radio system connection to the trains approaching the interlocking. For this reason, one BCP wayside location at each interlocking will be assumed initially. System design will consider the possibility of one BCP wayside location serving multiple interlockings. Within non-ATC territory at automatic signal locations, a PTC radio will be deployed to provide ACSES II wireless coverage. In

Section 3: Technology August, 2012 Page 3-7 PTC Implementation Plan

MBTA Revision 4

addition to the quantity and location of the BCPs, system RF coverage requirements will also determine parameters such as RF power, frequency (channel) selection, antenna directional patterns and the height of the antennas. Other design considerations that will affect the data radio technology include interference issues, data throughput and latency requirements, redundancy and resilience requirements, encryption and network management.

3.8.2 System-wide Communications Network The backhaul communications system will connect both control centers housing the TSR Servers to the wayside locations via MBTA’s existing System-Wide Communications Network. This system is equipped to transport a variety of communications and protocol platforms, including TCP/IP over Ethernet. As part of the system design each PTC wayside location will be evaluated to determine what additional communications links, if any, must be enhanced and where additional wayside PTC components shall be located.

3.9 PTC WAYSIDE SUBSYSTEMS

3.9.1 Wayside Sub-System The MBTA wayside PTC system will consist of two main areas of operation: interlocking limits and automatic block territory. Within these two areas, the wayside PTC system will provide civil speed enforcement and positive stop enforcement where required. The wayside PTC system requires, at minimum, wayside interface units, base communication radio packages, and transponders (refer to Figure 3-3 PTC Wayside System).

3.9.2 PTC Wayside Equipment

3.9.2.1 Wayside Interface Units Wayside Interface Units (WIU) will be installed at every interlocking on MBTA PTC operating territory and at every automatic signal location in ABS territories without ATC. The WIU is a vital microprocessor controller that provides a direct interface to the existing vital wayside signal system, with an interface to the associated BCP for radio transmission to the onboard ACSES II system. The WIU will interface with three types of vital signal systems on the MBTA Railroad; vital relay, single vital processor, or zoned vital processor, consisting of multiple processors. The WIU reads the real time status of all signals (Proceed Cab aspect status, Absolute Block Signal aspect status) and all interlocked switch positions (normal or reverse). The WIU will be in compliance with the safety criteria and processes requirements of Title 49 of the Code of Federal Regulations, Part 236. The WIU will be immune to the effects of any electromagnetic or electrical interference generated from within or outside the signal enclosures. The WIUs will either be rack or wall mounted or integrated into existing microprocessor systems by addition of circuit boards. The discrete wiring for the WIU, to either vital

Section 3: Technology August, 2012 Page 3-9 PTC Implementation Plan

MBTA Revision 4

relay or vital processor, will comply with all applicable requirements of Title 49 of the Code of Federal Regulations Part 236.

3.9.2.2 Transponders (existing, Shore Line) Transponders are passive devices mounted between the rails installed in sets of from 2 to 4. The transponders require no energy source other than that transmitted from a passing train. All transponders are physically identical. The programmable EPROMs within the transponders contain the unique safety critical site-specific data. The transponder will transmit encoded information about the speed restriction ahead including but not limited to:  The actual distance to the beginning of the next speed restriction(s), or speed change;  The target speed of all restrictions between this transponder set and the next transponder set and all restrictions beyond the next transponder set that cannot be met by reductions from maximum track speed at the next set;  All speed upgrades between this transponder set and the next;  The ruling grade or "equated" distance to the target, if the target speed is lower;  Transponder type, location, and track number;  The encoder address and radio channel  The actual distance to the next transponder location and necessary sync and check bytes to transmit a vital, fail safe, message;  The distance to the next Interlocking home signal; to be included on at least two transponder sets in approach to the interlocking signal, at the distant signal, and the last previous transponder set-location in approach to the distant signal. Transponders are located at all interlocking home signals and then at master locations, cut sections and grade crossings as necessary to meet the requirements of the MBTA PTC system. Transponders presently exist on the Shore Line for use by Amtrak’s NEC service.

3.9.2.3 Base Communication Package The BCP data radio system provides a wireless communication path from the wayside interface unit to a locomotive when reporting the status of the wayside device. Communication with more than one WIU through a common BCP will be supported. In addition, the BCP is providing a link between the locomotive and the safety TSR server at one of the control centers for current TSR information flow through the backhaul communication network and the designated wireless radio network.

3.9.2.4 Wayside Power Supplies The WIUs located in signal system CILs will be powered from the same power source as the signal system. The signal system is composed of both vital and non-vital logic. Vital

Section 3: Technology August, 2012 Page 3-10 PTC Implementation Plan

MBTA Revision 4

signal logic is powered by separate 12 VDC supply while the non-vital signal logic is powered by another 12 VDC or 24 VDC battery supply. The WIUs will only utilize the battery supplies used for the vital signal system. The BCP will utilize the battery supplies used for the non-vital signal system through DC-to-DC converters over line to new radio enclosures.

3.10 PTC ONBOARD SUB-SYSTEMS The following section describes the onboard components of the MBTA PTC system only. Figure 3-4 details a block diagram of the various components of the onboard ATC/ACSES II sub-system.

3.10.1 PTC System Components

3.10.1.1 Onboard Computer The Onboard Computer (OBC) consists of several Printed Circuit boards. It is a vital system. It employs both hardware and software crosschecking techniques to ensure vital operation. The OBC processes the data obtained from the transponders and via a data radio (MCP) to enforce permanent and temporary speed restrictions. The OBC also provides the vital signal to enforce positive stop where required. The OBC is housed inside an equipment box. The boxes are currently located in suitable locations that were selected during the initial installation based on the availability of space and interface to other vehicle subsystems. See Figure 3-4 for more details about onboard PTC architecture.

3.10.1.2 Scanner Antenna System The system consists of under car mounted scanner antenna, cable box (CTV), and transmission and receiver circuits. CTV is mounted close to the scanner antenna to minimize the RF power loses. Remaining circuits are housed in the MBTA ACSES II system equipment box and interface with the OBC. This is basically a loop antenna. When the vehicle is in motion, the scanner antenna is turned on. The CTV generates 27.115 MHz carrier frequency for the scanner antenna to continuously transmit this sweep frequency downwards to the tracks. When the train passes over the transponder, this carrier signal powers the transponder. The transponder sends a 4.5 MHz signal back to the train via the same MBTA ACSES II system scanner antenna with coded information representing the restrictions ahead. The technology is solid state and designed for stable operation over the entire temperature range and battery voltage variation of the vehicle.

3.10.1.3 Mobile Communication Package The MCP consists of data radio and roof mounted antenna. The MCP communicates with the BCP radio system to receive upcoming TSRs and interlocking route status. This is a solid-state transceiver that operates from its own regulated power supply. Primary power comes from vehicle battery system. The radio is certified to meet all FCC

Section 3: Technology August, 2012 Page 3-11 PTC Implementation Plan

MBTA Revision 4

requirements for frequency stability, power level, harmonics and Electromagnetic Interference (EMI) (Reference Section 3.3.1).

3.10.1.4 Speed Sensor A dedicated speed sensor is used to measure train speed. The ACSES II OBC will use this information to enforce speed restrictions and determine train travel distance. The locations of the speed sensors are vehicle specific. The speed sensors are of the passive, reluctance type with two-wire output and require no source of regulated voltage.

3.10.1.5 Operator Display ACSES II OBC provides the necessary signals to the Operator display for the train operator to know current speed restriction and associated warnings. The display also provides the system status information to the train operator. The technology is solid state.

3.10.1.6 Brake Interface System The brake interface system includes means to apply a full service penalty brake, and if needed emergency brakes. It also includes sensors to check brake application and suppression. The interface hardware is vehicle specific depending upon type of brake system on the vehicle.

3.10.1.7 Electrical Systems Power Supply for OBC: The OBC is powered from a solid state, switching power supply that supplies the various regulated and filtered voltages required for operation. The primary power comes from the vehicle battery system. The power supply protects the OBC from all surges, variations in voltage and EMI present on the battery system. Power Supply for MCP: The MCP will have its own dedicated solid-state power supply similar to the OBC. The regulated voltages will be those required by the MCP. EMI / EMC: The original installation was planned to include considerations to protecting equipment and included appropriate shielding, grounding, filtering, frequency avoidance, physical separation and other methods used to avoid EMI and achieve EMC within the vehicle. The installation was proven and validated at the initial vehicle level testing.

3.11 MISCELLANEOUS COMPONENTS Miscellaneous components include:  Operator console mounted acknowledgement button.  Departure test start button. The train operator is required to acknowledge specific MBTA ACSES II system warning alarms to forestall automatic penalty brake applications. The PTSO bypass button and the ACSES II system cutout switch locations are vehicle specific and easily recognizable

4 COMPLIANCE [§ 236.1011(a)(2)]

4.1 PTC SYSTEM CERTIFICATION The majority of track upon which MBTA operates is owned by MBTA (Host railroad). Most of the MBTA’s track has some freight (tenant railroad) operation. Due to the mixed use of tracks MBTA is required to have a PTC solution that will facilitate tenant railroads to be FRA compliant. MBTA also has an interoperability agreement with Amtrak for NEC operation. In light of this, MBTA will be pursuing PTC solutions similar to Amtrak NEC and capable of accommodating tenant railroad operations.

4.1.1 Utilization of Existing Type Approval and/or PTCDP MBTA will be utilizing the existing type-approved ACSES II logic. MBTA will reference the Amtrak approved PTC approach as a type-approved system. Wherever the design deviates from the basic ACSES II logic, a detail description will be submitted to the FRA as part of a supplement to the submitted PTCIP. During the planned extensive testing and validation of the MBTA’s PTC System, if the MBTA or FRA determine that additional supporting documents are needed, the MBTA will work with the selected PTC system supplier to make that a requirement in order to get PTC certification.

4.1.2 Certifying the Validity of Type Approval According to §236.1013(c) in the proposed rule, “each Type Approval shall be valid for a period of 5 years, subject to automatic and indefinite extension provided that at least one PTC System Certification using the subject PTC system has been issued within that period and not revoked.” MBTA will maintain its Type Approval status.

4.1.3 Handling of Unique Aspects of the PTCDP and Type Approval MBTA North Side operation is under ABS rules. MBTA PTCIP section 3, with additional support documentation in Section 14, provides the description of variance from type approved ACSES II. MBTA does not foresee any request to be non-compliant. During the PTC design and validation period MBTA will submit additional documents to identify all the variances and any unique aspects of MBTA’s PTC system design. This document will include references to a complete PTCDP approved for Amtrak and language that amends or replaces language in the referenced Amtrak PTCDP. Throughout the entire development and design process, MBTA will keep the FRA fully engaged and provide the FRA with all necessary information and documents. This will help to ensure MBTA’s compliance with PTC safety certification as the PTC system develops

4.1.4 Deliverables MBTA will supply the following deliverables to the FRA to support a petition for PTC System Certification: 1. PTC Implementation Plan (PTCIP)

Section 4: Compliance September, 2010 Page 4-1 PTC Implementation Plan

MBTA Revision 2

2. Reference number(s) for PTC Development Plan (PTCDP) of Amtrak. 3. MBTA variances and exceptions to reference PTCDP. 4. PTC Safety Plan (PTCSP) The PTCSP submitted by MBTA will include the following elements: 1. Design criteria 2. Drawings and technical specifications of the PTC system 3. Test Plans and Reports for commissioning of the PTC system 4. Product operations and maintenance documentation 5. Product training documentation

4.2 RISK ASSESSMENT The successful implementation of PTC on MBTA’s territory is dependant upon a number of associated risks. Although the potential for technical risks may exist, none are anticipated at this time that would create difficulty in deploying the PTC system by the December 31, 2015 completion date set by the FRA. Notwithstanding, the MBTA does have significant concerns associated with the financial resources required to support of PTC. End of Section

5 INTEROPERABILITY This section describes how the MBTA PTC system will provide for interoperability between the host and all tenant railroads on the territory required to be equipped with a PTC system in accordance with Part 236 Subpart I. The following carriers are presently tenant railroads on MBTA territory: 1. National Railroad Passenger Corporation (Amtrak) (AMT) 2. CSX Transportation (CSXT) 3. Massachusetts Costal Railroad (MC) 4. Fore River Railroad (FRVT) 5. Norfolk Southern (NS) 6. Pan American Railway (PAR) 7. Providence & Worcester (PW) The Fore River Railroad accesses MBTA property on average 5 times per week for one round trip from Adams Junction on the Greenbush Branch to Braintree on the Middleboro Line for a total of approximately 2 miles per round trip. This level of activity serves as the basis for an exception for the Fore River Railroad to install PTC under the criteria established in Part 236.1006 (b) (4) of Subpart I. The Massachusetts Coastal Railroad accesses MBTA property on average 3 – 4 times per week for one round trip on the Middleboro Line from Bay (MP 36.44) to Mid (MP 33.96), a total of approximately 2.5 miles per round trip. This level of activity serves as the basis for an exception for the Massachusetts Coastal Railroad to install PTC under the criteria established in Part 236.1006 (b) (4) of Subpart I. The following railroads will be required to have PTC-equipped locomotives in order to gain access to MBTA PTC-equipped territory: 1. National Railroad Passenger Corporation (Amtrak) (AMT) 2. CSX Transportation (CSXT) 3. Norfolk Southern (NS) 4. Pan American Railway (PAR) 5. Providence & Worcester (PW)

5.1 RAILROAD AGREEMENT PROVISIONS RELEVANT TO INTEROPERABILITY [§ 236.1011(a)(3)(i)] MBTA has “Letters of Understanding Implementation of Positive Train Control” with MBTA Tenant Railroads (Ref: Section 14 Appendix B). These letters of understanding are amendments to the following agreements that are in place between MBTA and its tenant railroads:

Section 5: Interoperability August, 2012 Page 5-1 PTC Implementation Plan

MBTA Revision 4

• Amtrak – MBTA / Amtrak Agreement for Use and Maintenance of the Attleboro Line dated July 1, 2003. • CSX Transportation (CSXT) – MBTA / CONRAIL Trackage Rights Agreement dated July 1, 1985 (transferred to CSXT as part of the acquisition of segments of CONRAIL). • Norfolk Southern (NS) – MBTA / CONRAIL Trackage Rights Agreement dated July 1, 1985 (transferred to NS as part of the acquisition of segments of CONRAIL). • Pan American Railway (PAR) – MBTA / Trustees for the Former Boston and Maine Railroad Agreement dated December 24, 1976, • Providence & Worcester (P&W) – MBTA / P&W Agreement for Use of Tracks dated December 8, 1982. The MBTA Positive Train Control – The Letters of Understanding has both parties (Host and Tenant) seek to implement PTC technical solutions which meet the requirements of the interoperability as defined in §236.1003(b).

5.2 TECHNOLOGY APPLICABLE TO INTEROPERABILITY [§ 236.1011(a)(3)(ii)] This section describes the technology proposed to achieve interoperability between MBTA and its tenant railroads. The discussion considers two basic interface scenarios. The first interface is where all locomotives of tenant carriers entering the MBTA territory will be fully ACSES II and ATC/cab signal equipped. The second interface is where all locomotives of tenant carriers entering the MBTA territory will be fully equipped with the Class 1 railroad-defined and FRA-approved I-ETMS type approved system.

5.2.1 ACSES II and ATC equipped tenant locomotives. Similar to MBTA vehicles, tenant railroad locomotives will communicate with MBTA control office safety servers and receive all the necessary applicable temporary speed restrictions before entering the MBTA PTC territory. There will be a transponder set at a safe distance prior to entering the PTC territory to enforce a positive stop if switches are not lined up for normal operation. Once proper communication is established and confirmed, the tenant locomotive will enter the MBTA PTC territory and follow the same logic as ATC and ACSES II equipped MBTA trains.

5.2.2 I-ETMS equipped tenant locomotives Refer to Figure 5.1, which shows how I-ETMS equipped tenant locomotives will receive messages on MBTA PTC territory. A home signal at the interlocking prior to entering MBTA PTC territory will clear only if the proper communication is established and confirmed between a tenant locomotive and the MBTA control office. The MBTA control office will have an I-ETMS compatible back office server. The MBTA control office PTC workstation will send ACSES II messages and I-ETMS

Section 5: Interoperability August, 2012 Page 5-2 PTC Implementation Plan

MBTA Revision 4

messages to each system independently. MBTA WIUs will also have capabilities to broadcast ACSES II messages and I-ETMS messages. With this dual capability, tenant locomotive will be able to operate over MBTA PTC territory. Figure 5-1

5.3 OBSTACLES TO INTEROPERABILITY [§ 236.1011(a)(3)(iii)] MBTA plans to implement proven and in-service systems to meet interoperability requirements. All the hardware and software to interface with MBTA control office, WIU, and Base station will be the same as that being tested and proven by Class 1 railroads for I-ETMS operation. MBTA takes the responsibility for the interoperability requirement and will work with tenant railroads and the FRA during, implementation, testing and verification. Apart from the technical issues, MBTA will have full partnership with tenant railroads in writing operating rules and providing operator training.

5.4 LETTERS OF UNDERSTANDING RECEIVED AT TIME OF FILING The following Table 5-1 indicates the status of letters of Understanding as of the time that the MBTA PTCIP was filed:

6 INSTALLATION RISK ANALYSIS [§ 236.1011(a)(4)]

6.1 GENERAL OVERVIEW The installation risk analysis and subsequent prioritization for the deployment of the MBTA Commuter Railroad PTC system is presented in this section. The analysis considers a number of factors that are relevant in identifying and analyzing the risk associated with mainline track segments of a commuter rail system with freight tenants. The actual data from 2008 is used for the volume of freight and volume of hazardous materials. Factors considered are: • volume of passenger traffic • volume of freight • volume of hazardous materials • route or segment length • interlocking density (number of interlockings per mile) • track grade and curvature • presence or absence of block signal and train control systems • presence or absence of wayside hazard detectors • density of grade crossings (both highway-rail and rail-rail) • single versus multiple track territory • density of track turnouts and crossovers • population density along the route • presence of other equipped and non-equipped traffic along route (shared track) • speed of train operations • past incidents • passenger station density In order to determine the weight that each defined risk factor carries within the analysis, each factor is evaluated and assigned a risk rating between zero (0) (no risk) and ten (10) (highest risk) that defines the relative level of risk associated with each factor. This risk rating is not associated with the scoring of track segment measurements, rather a value that defines the strength of a factor relative to other factors. The risk rating is used to rank the risk factors from highest to lowest risk (See Table 6-2 for strength definitions and Table 6-3 for the assigned order of strength associated with the risk factors). A rating system of ten discrete levels was used to provide high resolution for this ranking process.

Section 6: Installation Risk Analysis September, 2010 Page 6-1 PTC Implementation Plan

MBTA Revision 3

Once the relative level of risk of each risk factor has been assigned, a weighting value is determined for each factor. The weighting value for a risk factor is calculated by dividing that factor’s risk rating by the sum total of the individual factor’s risk ratings. A risk factor’s weighting value is described mathematically as:

n weighting _ valuei = risk _ rating i * ∑ risk _ rating k k =1 where n is the total number of risk factors (See Table 6-4 for a summary of the risk factors and the associated risk ratings and weighting values) In order to quantify the risk associated with the measurement of a risk factor, the range of each factor is defined and a scoring value of between zero (0) and five (5) is distributed across the range. With this scoring system, 0 corresponds to no risk and 5 is the maximum risk (See Tables 6-5 and 6-6 for a summary of the risk factors and their respective ranges). Once the scoring foundation has been established, the subject railroad is evaluated and divided into logical mainline track segments. These segments may be further divided into track sections associated with a main line track segment based on risk factor variances within the segment. Table 6-7 provides a summary of the main line track segments analyzed in this analysis. Each defined track section is then evaluated against the defined risk factors. Data associated with each risk factor is collected utilizing track maps, timetables, train schedules and other data sources. Based on these data, a measurement value for each risk factor is determined. The score (between 0 and 5) corresponding to the measurement value of a risk factor is then multiplied by the respective weighting parameter to determine the risk associated with that factor. The installation risk associated with a track section is the sum of the individual risk factor results (See Table 6-8 through Table 6-30 for risk results of each track section and Table 6-31 for a summary of the results). Finally, the risk results for the track sections associated with a main line track segment are averaged to determine the segment’s overall risk The risk associated with the main line track segments are subsequently prioritized for installation (See table 6-32 for the prioritized listing). The installation risk analysis provides the following: • a description of the rail network and its operations • a definition of the risk factors and associated measurement units • a definition of and justification for the weighting of each risk factor • a definition of the mainline track segments • a calculation of the risk associated with each mainline track segment

Section 6: Installation Risk Analysis September, 2010 Page 6-2 PTC Implementation Plan

MBTA Revision 3

• a prioritization of the installation of PTC for each mainline track segment based on the levels of risk and consequences • identification and justification of mainline track segment exclusions The steps associated with the risk assessment of a mainline track segment are: • identify the mainline track segment under analysis • gather and record data associated with each risk factor • quantify the risk associated with each risk factor based on the measured value and defined weighting value • quantify the total risk as the sum of the risks of the individual risk factors Mainline track segments of highest assessed risk are identified and prioritized for PTC deployment. In instances where PTC systems are deployed on track segments of lower risk first, an appropriate justification is provided.

6.6 MAINLINE TRACK SEGMENTS Segmentation of the MBTA mainline track first considered the primary branches. The intent was to score each MBTA branch as an entire entity and evaluate installations according to risk associated with these branches. It was determined, however, that some risk factors were not consistent over entire branches. To accommodate these varying conditions, mainline track segment boundaries were defined at locations were fundamental risk factors vary. The fundamental risk factors used in segmentation of mainline track are as follows: 1. number of tracks (segmentation occurs where the number of tracks changes) 2. signaling system and method of operations (segmentation occurs where the signaling system and method of operations changes) All other risk factors are evaluated within a mainline track segment. Where segmentation boundaries occur at an interlocking or at a station, the interlocking or station is counted in both adjacent mainline track segments. The mainline track segments owned or operated by MBTA and included in the installation risk analysis are defined in the table below. Definition of the segmentation is included in the “Description” column.

MBTA Revision 5

7 DEPLOYMENT SEQUENCE AND SCHEDULE

7.1 GENERAL This section defines the sequence and schedule to implement MBTA’s PTC System for all mainline tracks on MBTA territory, with the exception of the already FRA PTC- compliant Shore Line, by December 31, 2015. The schedule is shown in Section 14 – Appendices of this plan. The schedule is expressed in terms of the following four major project milestones; PTC Design, Material Procurement, Construction and System Verification.

7.2 SEQUENCE These four major milestones will be applied to each of the nine (9) MBTA rail lines in Section 6 – Risk Analysis of this plan which determines the risk ranking for each rail line.

7.3 SCHEDULE The schedule will be determined based on a number of factors including the risk analysis; the number and complexity of locations requiring PTC installations; MBTA/MBCR’s force account availability; pre-PTC reconstruction to resolve: outdated signal systems; unavailable location space conditions; and unavailable location power conditions. Location variables that will affect the schedule include number of tracks, housing availability, type of wayside device and PTC equipment capacities. Numerous sections of the MBTA’s signal system will require pre-PTC reconstruction to resolve problem locations. Signal location problems include outdated signal systems; unavailable location space conditions; and unavailable location power conditions. Several sections include signal apparatus manufactured and/or installed more than 50 years ago (see Table 7-1). The same equipment resides in housings which are in need of repair to conceal equipment from the environment. Pipe connecting a new housing to these older housing is not warranted. Other housings, which have no environmental protection issues, have no room left to install new PTC equipments and the power supply and condition units. Pipe connection at these locations may work where actual ground area exists adjacent to the existing signal housing.

MBTA Revision 5

The time and costs associated with the reconstruction will impact the order and availability of locations within the risk-based scheduled deployment. Work force availability, equipment and materials availability, maintaining some route continuity (according to a pooling of similar risk Lines) are all criteria for the scheduling of PTC implementation and deployment. In many areas there are natural break-points which will be used as demarcations between PTC and Non-PTC lines during the MBTA’s phased installation.

7.4 PTC DESIGN In order to meet an aggressive project schedule, the PTC Design includes initial design sub-tasks for components of the PTC Implementation project that can be progressed earlier in the project that are independent of the system design and equipment to be furnished. The subtasks include PTC Wayside Design, Wayside Survey/Mapping, PTC Radio/Communication Design and Back Office Design. The PTC Onboard Design is already equipped via the ACSES II System, working alongside the ATC System.

7.4.1 PTC Wayside Design Existing circuit plans will be modified and new plans produced to show the additional components and wiring required for each signal location to be monitored by the PTC wayside equipment. The design will vary depending on the type of location. Major components of the wayside design will include: • Signal lighting and switch indication interface wiring to the WIU, • Cable connections between the WIU, radio and antennas • Power distribution for PTC wayside components • Signal aspect/radio code chart Table 7-2 – Wayside and Communications Installations Percent Division Line Name Complete 2011 – 0% North Side Newbury/Rockport Line 2012 – 100% 2011 – 8% North Side Haverhill/Lawrence Line 2012 – 100% 2011 – 40% North Side Lowell Line 2012 – 100% 2011 – 0% North Side Fitchburg Line 2012 – 40% 2013 – 100% 2011 – 0% 2012 – 0% North Side Wildcat Line 2013 – 0% 2014 – 100% 2011 – 0% South Side Framingham/Worcester Line 2012 – 0% 2013 – 100%

7.4.2 PTC Onboard Design The existing ACSES II PTC onboard design on each MBTA vehicle will be upgraded as required in part of the overall MBTA PTC system design process. Completion schedule is shown in section 8 – table 8-1.

7.4.3 PTC Radio and Communications Design This task will evaluate and define the required PTC radio coverage area and communications infrastructure. A survey of MBTA’s existing communication infrastructure capabilities will be conducted. Radio propagation analysis using software simulation and physical coverage tests will be performed to establish the requirements for the PTC radio blanket coverage for the entire MBTA’s region of operation. If required, new communications infrastructure will be deployed to ensure reliable PTC operation.

Section 7: Deployment Sequence and Schedule August, 2012 Page 7-4 PTC Implementation Plan

MBTA Revision 5

7.5 MATERIAL PROCUREMENT MBTA will procure the PTC material for the components of the PTC Implementation project that can be progressed early in the project that are independent of the System design.

7.5.1 Wayside Material Major PTC components needed to interface with the wayside signal location include: • Wayside Interface Unit • PTC Data radio Package(s) • Batteries and charger • DC to DC Converter • Current sensing Hall Effect sensors • Lightening/Surge Protectors • VHF Antenna(s) • Fuses and terminal blocks • Internal case wiring and connecting cables Depending on the type of location being monitored additional materials may include: • Auxiliary equipment housing • Additional Wayside Interface Units • Vital relays

7.5.2 Onboard Material All of MBTA locomotives and Cab Cars are equipped with ACSES II and ATC equipment with the exception of the Bombardier built Cab Cars. MBTA currently has all of the ACSES II onboard components in inventory and will complete the installations for these remaining 26 vehicles utilizing an in house workforce. Upgrades to existing onboard equipment may include: • 220 MHz Radios • Radio Adapter Cable and Antenna • Software Upgrade

7.5.3 Communications Material Communications network will be based on data radio and backhaul communication links to provide reliable conduit for information flow to and from a locomotive to the wayside devices and CROCC. Refer to sections 3.3.1.3; 3.3.1.4; and 3.3.1.5 for the major communications system components’ listings.

MBTA Revision 5

7.6 CONSTRUCTION This section identifies the tasks required to install all wayside, vehicle and communication devices or subsystems by MBTA/MBCR Force Account and contractors as a part of the MBTA PTC system.

7.6.1 Wayside Construction All PTC wayside components will be installed and wired by qualified signal construction crews. Tasks include transporting PTC components to the wayside locations, installing foundations and cases mounting, wiring and adjusting PTC components.

7.6.2 Vehicle Retrofit As mentioned in section 7.5.2, all MBTA vehicles are equipped with ACSES II and ATC equipment with the exception of the Bombardier Cab Cars. The Bombardier Cab Car 1624 had the onboard ACSES II hardware installed as part of the initial ACSES I Project. The installation was not entirely completed because the vehicle was never used in ACSES II territory but it was completed to the level to ensure the bracket design and installation met MBTA standards. MBTA currently has all of the ACSES II equipment in inventory to complete the installation for this car and the remainder of the Bombardier Cab Car Fleet. The installation plan, testing and commissioning of these vehicles will follow in the same format as the original project. Radio and other equipment modifications will be scheduled based on material deliveries and will be performed by a qualified workforce.

7.6.3 Communications Construction Any new communications infrastructure will be constructed according to the PTC communication design and construction plans. MBTA’s communications department will supervise the construction of additional base stations, microwave, electrical and fiber links. New structures will be built in accordance with applicable rules and regulations. All additions and modifications to the existing communications infrastructure will have a significant influence on the overall construction schedule. Impact time to the existing communication network will be minimized. In case the existing communications link functionality will need to be interrupted, alternative communication paths and channels will be employed to insure smooth operation of MBTA’s communications network.

7.7 EQUIPMENT VERIFICATION This section identifies the tasks required to place in service all wayside, vehicle and communication devices and subsystems and the entire PTC system for all MBTA rail lines.

7.7.1 Onboard Subsystem Verification Each new onboard installation will be tested and validated with the same in-house quality control processes to ensure consistency in workmanship. Following in the same process

Section 7: Deployment Sequence and Schedule August, 2012 Page 7-6 PTC Implementation Plan

MBTA Revision 5

as in the original project, each vehicle will be tested statically in the shop then dynamically in ACSES II territory with a team of test personnel to validate the system operation. All system upgrades and modifications will be controlled and managed using the same proven techniques.

7.7.2 Communications Subsystem Verification Communications system functionality will be tested according to the PTC testing and inspection plan. Testing will be completed at a number of levels and in phases prior to final field-testing and acceptance of the PTC system. The test will include component and unit tests, as well as system level tests for the whole communications network.

7.7.3 System Verification MBTA will institute a pilot program and has determined that from Somerville Jct. to Winchester on the Lowell Line is the best site for the pilot testing. There are many workings of the Railroad in operation in this area which will make the testing more thorough than other possible sites. In this area there is freight, Amtrak, two crossings, a hand operated switch, a Rule 261 signal system and electronic track circuits. The pilot program will also include designated rolling stock to verify operation. The pilot program will be used to validate the rest of MBTA’s lines through verification testing as a part of the commissioning process.

7.8 PTC DEPLOYMENT PLAN SCHEDULE MBTA has created a PTC Deployment Plan Schedule. A copy of the schedule which was created in Microsoft Project is located in Section 14 – Appendices. The schedule logically and systematically shows each step required for the PTC total deployment. It goes through Design, Procurement, Construction of Wayside and On Board Equipment, Verification, and Start-up. Under the Deployment Plan, the equipment installations will be progressing on two fronts simultaneously. This will be with the installation of the wayside equipment and the rolling stock. When the wayside equipment is installed and a line is 100% complete with the necessary equipment and also when a sufficient amount of rolling stock equipment has been completed to be able run at full revenue service, including spares, the branch will be brought on line. The responsibility of overseeing these installations will be the MBTA PTC Program Manager. The sequence of line start-ups is in Table 7-3. This table is derived by the PTC Deployment Plan Schedule located in Section 14. The quantity of equipment which needs to be installed on all lines and rolling stock is known. Therefore, for reporting purposes both internally and to the FRA, a percentage complete will be derived between installed and uninstalled equipment.

11 EXCEPTIONS TO RISK-BASED PRIORITIZATION [§ 236.1011(a)(9)] Logistics and impracticalities may result in the need to deviate from the installation priorities identified by the risk analysis. Therefore, installation exceptions to the risk- based prioritization required by 49 CFR Part 236, Subpart I, § 236.1011(a)(4) and presented in Section 6 of the PTCIP are presented in this section. MBTA takes no exception to the installation sequence resulting from the risk analysis and will therefore deploy the wayside segment of the PTC system according to the outcome of the analysis.
