It assists in optimization of metro infrastructure investment and running of efficient train services on the network. 11.2 SIGNALLING AND TRAIN CONTROL 11.2.1 Overview Metro carries large number of passengers at a very close headway requiring a very high level of safety enforcement and reliability. At the same time heavy investment in infrastructure and rolling stock necessitates optimization of its capacity to provide the best services to the public. These requirements of the metro are planned to be achieved by adopting ‘CATC’ (Continuous Automatic Train Control System) based on “CBTC” (Communication based Train Control System) which includes ATP (Automatic Train Protection), ATO (Automatic Train Operation) and ATS (Automatic Train Supervision) sub-systems using radio communication between Track side and Train. This will: • Provide high level of safety with trains running at close headway ensuring continuous safe train separation and for bidirectional working. • Eliminate accidents due to driver passing Signal at Danger by continuous speed monitoring and automatic application of brake in case of disregard of signal / warning by the driver. • Provides safety and enforces speed limit on section having permanent and temporary speed restrictions. • Improve capacity with safer and smoother operations.

Positive Train Control (PTC)
Positive Train Control (PTC) Positive Train Control Safety is Amtrak’s top priority. Amtrak is a leader in the installation of Positive Train Control (PTC), a safety technology designed to match train speed to track conditions for improved safety. Positive Train Control provides an added layer of safety. Installation and maintenance of PTC is the responsibility of the railroad that controls the track. Amtrak Infrastructure In December 2015, Amtrak activated PTC on track between New York and Washington, D.C., completing installation on most Amtrak-owned infrastructure on the Northeast Corridor (NEC) spine. PTC has been installed between Boston and New Haven since 2000. The only exceptions are seven miles, all of which are located in or adjacent to terminal areas where trains move slower and automatic train control systems are in service. Of note, Amtrak is not responsible for installing PTC on the following segments of the NEC which it doesn’t control, between New York and Boston: Harold Interlocking east of New York Penn Station is the responsibility of the LIRR, and Metro-North Railroad is responsible for the 56 mile New Rochelle-New Haven segment owned by the states of New York and Connecticut. In early 2016, Amtrak activated PTC on the 104-mile Harrisburg Line. Amtrak has also installed and is operating PTC along the 97 miles of track it owns in Michigan and Indiana, where PTC was introduced in 2002. Amtrak is working on installation of PTC on other lines, including the 60 mile Springfield line (where a major double-tracking project funded by the state of Connecticut is underway), the 105 mile Hudson line between Poughkeepsie and the Schenectady area (leased by Amtrak), and the 135 mile Dearborn-Kalamazoo segment of the Michigan line owned by Michigan, as well as the Chicago Union Station terminal areas. -

System for Investigation of Railway Interfaces (SIRI)
6 System for Investigation of Railway Interfaces (SIRI) Sanjeev Kumar Appicharla 1Institution of Engineering and Technology 2The International Council on Systems Engineering, UK 1. Introduction This chapter presents an abstract system framework called ‘’System for Investigation of Railway Interfaces’’ (SIRI), to study potential or past railway accident(s). The aim of the study is to learn about the multiple causal factors (elements or conditions) which represented together can be called a cause leading to the undesired state called potential or accident situation. Safety studies like SIRI can be used in conjunction with the quantitative risk estimation method (PRA) to help highlight or uncover decisions leading to assumption of unreasonable risk or human error in engineering and management factors needs to be studied. Author accepts the viewpoint of George E.Apostolakis on the utility of quantitative risk analysis (QRA) or probability risk analysis ( PRA) techniques in general (E.Apostolakis 2004). The questions of human error and organisational learning are clarified later in the chapter in the context of acceptance of QRA method. The SIRI Framework uses synthetic mode of thinking as opposed to analytical mode of thinking. Analytical mode of thinking is like decomposing water which does no longer contains anything liquid and has taste. The SIRI Framework synthesises multiple study methods into a cohesive process represented as a system. The study methods used in stages to arrive at the decision of a potential accident situation in an unambiguous manner are Hazard identification method (HAZOP), Event Causal Factor Analysis (ECFA), Energy Barrier Trace Analysis (EBTA), accident investigation technique (MORT), and cognitive human factors framework (SRK) and systems thinking integrated into a cohesive system framework. -

GAO-20-516R, Positive Train Control: Railroads Generally Made Progress
441 G St. N.W. Washington, DC 20548 April 30, 2020 The Honorable Roger Wicker Chairman Committee on Commerce, Science, and Transportation United States Senate Positive Train Control: Railroads Generally Made Progress, but Several Must Meet Compressed Schedules to Meet Implementation Date Dear Mr. Chairman: Positive train control (PTC) is a communications-based system designed to automatically slow or stop a train in certain cases where it is not being operated safely. Over a decade ago, a federal law was enacted requiring the implementation of PTC by 42 railroads—including 30 commuter railroads, Amtrak, and several Class I and Class II/III freight railroads—to prevent train-to-train collisions and other types of accidents.1 The National Transportation Safety Board stated in 2018 that since the enactment of this law, it had investigated 22 rail accidents that could have been prevented by PTC. By statute, railroads were required to implement PTC by December 31, 2018, unless they met certain statutory requirements and requested an extension.2 Few railroads completed implementation by year-end 2018, so the Federal Railroad Administration (FRA) granted nearly all of the 42 railroads required to implement PTC an extension up to December 31, 2020. However, FRA is not authorized to grant further extensions. Over the years, we have periodically reported and testified on railroads’ progress implementing PTC.3 We have consistently identified the challenges arising during the complex and lengthy implementation process, which involves nearly all major rail lines and almost every aspect of railroads’ operations. In July 2019 we reported that most railroads had completed the earlier stages of implementation, such as equipment installation, and were in various stages of testing 1Certain railroads were required to implement PTC by December 31, 2015. -
Enhanced ETCS L2/L3 Train Control System
Advanced Train Control Systems 113 Enhanced ETCS_L2/L3 train control system D. Emery Laboratory for Intermodality and Transport Planning (LITEP), École polytechnique fédérale de Lausanne (EPFL), Switzerland Abstract The last decade has seen the development of the European Train Control System ERTMS/ETCS. This Automatic Train Protection system (ATP) was designed in three versions: ETCS_Level 1, 2 and 3. ETCS_Level_3 uses moving blocks and provides short headways. However, ETCS_Level 2 may also offer short headways provided suitable length of each block sections. The proposed train control system could be seen as an enhancement of ETCS-Level 2 or Level 3. The main advantage of this new control system is to provide shorter headways than ETCS can. This offers the potential for capacity increases, particularly for busy High Speed Lines (HSL). Keywords: ATP, braking curves, capacity, ETCS, ERTMS, headway, high speed line (HSL), interlocking, moving block, Semi-Automatic Train Operation (SATO). 1 Interoperability, safety and capacity with ETCS 1.1 ETCS for interoperability and safety The European Train Control System was firstly developed to offer to the European Rail community a common Automatic Train Protection system in replacement of the existing ones. In theory, this is needed urgently as more than Table 1: ETCS and some ATP spot transmission.
