The current stage of planning involves supporting the preparation of a reservation of the corridor to secure the proposed transit corridor and preserve the right of way. This proposal is a significant and strategically important opportunity for the future development of the Regional Rail Link Project and the Victorian Transport Plan. This report details the preliminary engineering design services provided by AECOM to the Department to enable determination of the minimum corridor footprint required to support the reservation planning process. This project overview summarises the preliminary engineering design services provided to the Department to enable determination of the minimum corridor footprint required and support the Planning Scheme Amendment process. The services provided have been incorporated to: • Determine the minimum functional requirements for the Proposed Transit Corridor of the Regional Rail Link Deer Park to West Werribee; • Design the proposed Regional Rail Link alignment and corridor footprint; • Prepare the Functional Design for the Proposed Transit Corridor; • Identify the future High Speed Design Standard requirements for the Railway; • Ensure that implementation of the Proposed Transit Corridor supports the Planning Scheme Amendment process; and to • Secure the right of way and protect the rail reservation required to deliver improved public transport services to regional and urban growth areas. Figure 1: Proposed Transit Corridor Route Map Regional Rail Link - Deer Park to West Werribee Preliminary Engineering Design Services 4 June 2009 Commercial-in-Confidence Page i Proposed Transit Corridor Design The Proposed Transit Corridor will be a new 30km reservation linking the Ballarat Rail Corridor at Deer Park in the north with the Geelong Rail Corridor at West Werribee in the south. Figure 2: Proposed Location and Route Map The Proposed Transit Corridor will include: • New Railway Reservation to facilitate the construction of dedicated Geelong Main Lines for Regional Rail Link services to run express to Geelong. • Improved Public Transport access to major urban growth areas in Melbourne’s outer west including Proposed Stations at Tarneit and Wyndham Vale. • Provision for up to 4 proposed future stations with modal interchange and park and ride facilities. • Provision for shared pathway network, linear parkland and integrated urban design. • Provision for future Western Freight Link Deer Park to Derrimut. • Provision for Suburban Electrified Lines to be extended from Werribee to Wyndham Vale. • Future proofing of the corridor to preserve future High Speed Passenger Services at permissible speeds up to 200km/h. Functional Requirements of the Operational Railway The Proposed Transit Corridor has been prepared to meet the functional requirements for operation of the railway by providing an alignment that enables Regional Rail Link services to travel at Permissible Line Speeds up to 160km/h. Further, the alignment has been designed to protect the introduction of high speed passenger services in the future with introduction of Enhanced Permissible Line Speeds up to 200km/h. The introduction of future high speed services will require the development of new track design construction standards suitable for passenger railway operations with line speeds up to 200km/h. Regional Rail Link - Deer Park to West Werribee Preliminary Engineering Design Services 4 June 2009 Commercial-in-Confidence Page ii Proposed Transit Corridor Configuration Generally the Proposed Transit Corridor has been configured to include up to 4 Broad Gauge Passenger Tracks within a footprint up to 60m wide.

  • Assessment of Transport Corridors 9
    PaRt 3: assessment of tRansPoRt CoRRiDoRs 9. Regional Rail link (west of weRRibee to DeeR PaRk) The proposal for the Regional Rail Link – west of Werribee to Deer Park is being planned in an integrated manner with the changes to Melbourne’s Urban Growth Boundary, the Outer Metropolitan Ring / E6 Transport Corridor and the preservation of grasslands areas in Melbourne’s west. The Regional Rail Link can allow urban growth areas in Melbourne’s west to be served by high-quality public transport infrastructure early on in their development. It is of strategic importance to Victoria in achieving its wider transport planning vision as outlined in The Victorian Transport Plan and urban growth planning as outlined in Melbourne 2030 and Melbourne @ 5 million. 9.1 Understanding the Corridor The Regional Rail Link – west of Werribee to Deer Park is a 30 kilometre long section of up to 50 kilometres of the rail project linking the Melbourne-Geelong railway west of Werribee to Southern Cross Station via the Melbourne-Ballarat railway, connecting at Deer Park. The other section of the Regional Rail Link uses the existing rail corridors between Southern Cross Station and Deer Park. Both sections of the overall Regional Rail Link can be developed independently of each other, although both are proposed to be developed together to reduce construction times and ensure overall project benefits are realised as early as possible. 9.2 assessment The selection and assessment process to determine the alignment for the Regional Rail Link – west of Werribee to Deer Park involved: > Preparing route concepts to identify a broad range of options considering engineering constraints and benefits.

  • Chapter 2 Track
    CALTRAIN DESIGN CRITERIA CHAPTER 2 - TRACK CHAPTER 2 TRACK A. GENERAL This Chapter includes criteria and standards for the planning, design, construction, and maintenance as well as materials of Caltrain trackwork. The term track or trackwork includes special trackwork and its interface with other components of the rail system. The trackwork is generally defined as from the subgrade (or roadbed or trackbed) to the top of rail, and is commonly referred to in this document as track structure. This Chapter is organized in several main sections, namely track structure and their materials including civil engineering, track geometry design, and special trackwork. Performance charts of Caltrain rolling stock are also included at the end of this Chapter. The primary considerations of track design are safety, economy, ease of maintenance, ride comfort, and constructability. Factors that affect the track system such as safety, ride comfort, design speed, noise and vibration, and other factors, such as constructability, maintainability, reliability and track component standardization which have major impacts to capital and maintenance costs, must be recognized and implemented in the early phase of planning and design. It shall be the objective and responsibility of the designer to design a functional track system that meets Caltrain’s current and future needs with a high degree of reliability, minimal maintenance requirements, and construction of which with minimal impact to normal revenue operations. Because of the complexity of the track system and its close integration with signaling system, it is essential that the design and construction of trackwork, signal, and other corridor wide improvements be integrated and analyzed as a system approach so that the interaction of these elements are identified and accommodated.

    DRAFT 59 Rail Futures Inc THE MELBOURNE RAIL PLAN Moving People in a City of 8 Million 25 May 2019 This paper has been prepared by Rail Futures Incorporated in the public interest. Rail Futures Inc is an independent non-partisan group formed to advocate cost effective rail and intermodal solutions for public transport and freight problems based on sound commercial, economic and social reasoning. Rail Futures members include experienced rail professionals, engineers, planners and economists. Melbourne Rail Plan 2019-2050, May 2019 Version 59 - DRAFT FOR COMMENT Rail Futures Institute 1 Foreword Melbourne once had one of the world’s best public transport systems. The forethought and planning of Victorians more than a century ago, and their capacity to value the welfare of Victorians of the future -us - as highly as their own, helped make Melbourne one of the world’s economically most productive and liveable cities. For the past few generations, myopia, carelessness and excessive valuation of the present over the future have been squandering that wonderful legacy. The economic and social life of this city will be deeply impaired by barriers to movement of people around the city unless chronic underinvestment over recent generations is remedied. The Melbourne Rail Plan 2019-50 demonstrates the way to correct the mistakes of recent generations, and that some contemporary Victorians are up to the challenge. The Report is comprehensive, creative and authoritative. It is an excellent foundation for rebuilding Melbourne to secure its position as one of the world’s most successful cities. Melbourne is growing more rapidly than any other large city in the developed world.

  • Florida High Speed Rail Authority High Speed Rail Project Civil Infrastructure Design Guidelines July 16, 2002
    Florida High Speed Rail Authority High Speed Rail Project Civil Infrastructure Design Guidelines July 16, 2002 1.0 Introduction It is anticipated that a high speed rail system will be constructed in the State of Florida under a design build operate and maintain (DBOM) contract. Preliminary engineering and environmental assessment are proceeding on the St. Petersburg to Orlando corridor in order to select a preferred alignment, satisfy the NEPA process and develop DBOM request for proposal documents. Multiple high speed ground transportation technologies exist, including diesel-electric and electric powered steel wheel/steel rail systems and magnetic levitation systems. Rail systems offer both conventional and tilt suspensions. The performance and infrastructure requirements of each technology are different. The key differences for alignment are the maximum speeds attainable with each technology – a range of 120mph to 250 mph. In order to enable the competitive marketplace to present the best option for the citizens of Florida, the Authority has not made a technology selection. This complicates the preliminary engineering task, as the alignments and infrastructure must be designed to allow the application of the range of technologies. The alignments must be designed, so as not to preclude the use of or unjustly penalize the performance of any technology. (One exception to this concept exists – Maglev systems shall not be permitted adjacent to the existing CSX railroad due in part to the perception by CSX that EMI may affect the performance of the CSX signal system.) The High Speed Rail Project Civil Infrastructure Design Guidelines are established to guide the preliminary design decisions in a manner consistent with these objectives.

  • Fundamentals of Railway Curve Superelevation with Explanation of Curve Radius and Degree of Curve
    Fundamentals of Railway Curve Superelevation with Explanation of Curve Radius and Degree of Curve By Jeffrey G. Hook Original April 20, 2010, Revised April 8, 2017 Centrifugal Force. Railway locomotives and cars, hereafter referred to as rolling stock, when rounding a curve may be considered as coming under the influence of centrifugal force. Centrifugal force commonly defined as: 1. The apparent force that is felt by an object moving in a curved path that acts outwardly away from the center of rotation. 2. An outward force on a body rotating about an axis, assumed equal and opposite to the centripetal force and postulated to account for the phenomena seen by an observer in the rotating body. For this article the use of the phrase centrifugal force or the abbreviation Fc shall be understood to be an apparent force as defined above. It shall also be understood that unless specified otherwise when the word curve is used it refers to a circular curve or simple curve, that being a curve of constant radius. Suspension Systems Considered. Only rolling stock suspension systems of conventional design, circa 1980, are considered for this article. Active or passive rolling stock center of gravity modifying devices or schemes such as tilting car bodies or trucks, or pendulum suspension schemes are not applicable to and the explanation of which is beyond the scope of this article. Effect of Centrifugal Force. When rolling stock rounds a curve and the rails of the track are at the same elevation, the plane of track is horizontal, the combination of the weight of the rolling stock W and the centrifugal force Fc will produce a resultant force Fr that does not coincide with the center line or axis of track.
