GEGN8651 Iss 1

This document provides guidance on assessment of changes that affect the interfaces between Control Command and Signalling (CCS) systems and train operations.

The intent of GEGN8651 issue one is to provide industry with guidance on assessment of changes that affect the interfaces between Control Command and Signalling (CCS) systems and train operations. It also helps Transport Undertakings and Proposers assess whether a planned change to a lineside signalling layout, or the way it is used, is fit for purpose in supporting the train driving task by establishing the adequacy of the presentation of information, by the lineside signalling system, to train drivers.
