ABSTRACT
The procedures for use in signalling failure situations in Great Britain (GB) are prescribed in the Modular Rule Book. This is a Railway Group Standard (RGS) and it sets out the mandatory requirements for direct application in the workplace. It includes day-to-day procedures relevant to all railway roles. RSSB is responsible for the management of all RGS, including the Rule Book, on behalf of the industry.
There is a process in place for changing RGS to ensure continuous improvement of safety, drive out unnecessary cost and improve business performance. Generally, such changes are proposed by industry stakeholders and the final decision regarding the change is made by consensus within a formal committee of industry representatives, managed by RSSB.
