RSSB2660 - T1137 Electrical and Data Control Compatibility between Trains

Descriptions

The project aims to investigate the electrical and data connectivity requirements for automatic couplers across a range of scenarios (including different train rescue situations), considering different technology enablers and business case factors to propose a standard protocol. This includes: Identifying Use cases •Documented scenarios of train rescue together with coupling/uncoupling procedures using standardised electrical and data automatic couplers. The scenarios should cover interworking between trains with distinct types of traction systems (electric, diesel and hybrid). In each case, the data/electrical control wires that need to be transmitted between the trains concerned has to be evaluated. •Exploration of other possible modes of operation between simple rescue and full interworking, and an evaluation of the business cases for these intermediate modes. •Explanation of full interworking between different train types (that is, electric, diesel, hybrid) and an evaluation of the data/electrical transmission required Defining and assessing the technological options •An evaluation of the technological challenge, that is, achieving the interface between the different existing Train Control and Management Systems (TCMS) and the vehicles being linked via standardised automatic couplers. This interface would allow interworking with other trains. •An evaluation of options for the transmission of data and electrical control wires between units and/or vehicles, starting with a technology search to identify existing or future products which might be suitable. The evaluation should consider the options particularly in relation to: -Business case -Safety integrity (Safety Integrity Level 4 is desired) •Defining a protocol for the transmission of data and electrical control wires between trains, recognising the need to achieve conformance of performance characteristics between distinct types of train and considering technological solutions to achieve this. Recommending actions •Preparing a report which: - Summarises options, in terms of modes of operation and associated business cases. - Recommends a standard protocol for the transmission of data and electrical control wires between units and/or vehicles. - Recommends technical solutions, potentially based on those available today and those anticipated in the future, for the transmission of data between units and/or vehicles. The evaluation should include consideration of business case and safety integrity.
