RIS-0734-CCS Iss 2

This document sets out requirements, rationale and guidance for signing of permissible speeds on the Great Britain (GB) mainline railway.

The content in RIS-0734-CCS issue two has been completely rewritten to provide better clarity on each requirement and to provide a robust rationale and guidance on how to meet the requirement.  The redrafted, revised and new content is intended to be easier to understand, which should reduce the likelihood of misinterpretation and misuse.  Additional requirements setting out which signs are used, reflect existing good practice which was not previously specified as prescriptive requirements.
