Outline Project Wide Specification Requirements

There are a number of criterion which need to be considered during the procurement and selection of the “project wide” specification for any new railway system. These are summarised as follows:‐

Operation

• Train Operational Speed (passenger and freight)

• Maximum Train Length (passenger and freight)

• Maximum Gradient

• Minimum Curvature (main lines and sidings)

• Vertical Curves

• Platform Length

• Station Capacities

• Passing loop Length

• Structure Gauge

• Crossover and Turnout Speeds

• Train Servicing and Maintenance Depots, Locations and Capacities

• Freight Yard Locations and Capacities

• Operating Procedures, Instructions and Rules

• Management and Administration Structure

Infrastructure

• Track Gauge

• Axle Load

• Ballast Specification and Minimum Ballast Depth

• Formation Crossfall

• Track Drainage

• General and Major Structures

• Level Crossings

• General Civil Engineering Support Structures

• Environmental Impact

• Procedures and Instructions for Infrastructure Maintenance

Railway System and Rolling Stock

• Train Control Systems

• Communication System

• Traction Power

• Arrangement of Substations

• Locomotives

• Rolling Stock

• Procedures and Instructions for Systems and Rolling Stock Maintenance

During the course of the project development, it is anticipated that, for each of the above railway disciplines, a series of performance specification will be developed by the nominated supplier or joint venture ERC contractor. ERC will review and check this documentation to ensure it is fully compatible with overall system requirements.
