RIS-0733-CCS Iss 1.3

This document sets out requirements, rationale and guidance for the application of lineside operational signs published in the RSSB catalogue. It also contains the index of lineside operational signs published in the RSSB standards catalogue and the process for including a new design or a change of use of an existing sign.

Appendix C has been updated to introduce new permanent and temporary power changeover signs AJ07 to AJ16 to support multi-mode trains. 

Other amendments have been made to existing signs set out in Appendix C including the withdrawal of sign AJ05 and updates to the application rules for signs AJ01, AJ02 and AJ04.

References to application rules have also been updated for signs in Appendices A.7, B.2, B.3 and B.4.

The changes form part of a suite of standards changes relating to the introduction of new permanent and temporary power changeover signs applicable to multimode trains. It is anticipated that this suite of changes will make some contribution to reducing the number of failed changeovers.
