RIS-0340-CCS Iss 2

This document was intended to be used by rolling stock owners and operators to assist with the procurement of the European Traffic Control System (ETCS) onboard equipment, and by suppliers in pre-empting likely product aspirations of Great Britain (GB) railway undertakings. It included requirements that may be used in the procurement of ETCS onboard equipment, which have been derived in conjunction with the requirements set out in the Baseline 3 suite of ETCS specifications. The standard was withdrawn on publication because the ERTMS Programme's ETCS onboard specifications document (NEPT/ERTMS/REQ/007) provides this information to industry under different change control arrangements, pending efficacy of the set of requirements. When the requirements are sufficiently proven a new or revised RSSB document will be proposed. ERTMS Programme specification (NEPT/ERTMS/REQ/007) supports a change control process that is more flexible to mange novel requirements. NEPT/ERTMs/REQ/007 is available via the RSSB website at: http://www.rssb.co.uk/improving-industry-performance/cross-industry-programmes/ertms.

All requirements have been reviewed to benefit from the experience gained from national and wider European deployment of the European Train Control System (ETCS). Some requirements have been revised to address developments in ETCS specifications, including baseline 3. Requirements relating solely to Baseline 2 have been removed.

New requirements incorporated are:

• ETCS onboard equipment tolerance for short duration cab opening.
• ETCS onboard equipment integration into the train systems to minimise complexity and quantity of components in interfaces.
• ETCS equipment to be appropriately protected electrically.
• Fault reporting and feedback of the ETCS onboard system not to be compromised by other systems.
• Opportunity to integrate AWS/TPWS controls into the ETCS DMI.
• Integration and compatibility of set speed controls with ETCS.
