GEGN8502 Iss 2

This document gives guidance for the introduction and operation of urban rail vehicles on or adjacent to the GB mainline railway. This guidance is intended to assist infrastructure managers and railway undertakings in understanding their responsibilities. It does not constitute a recommended method of meeting any set of mandatory requirements.

Since its first publication in February 1999, GEGN8502 has become outdated due to changes in GB legislation, rail standards, and new processes of acceptance and safe integration. These factors, along with major rail industry changes and the UK's exit from the EU, necessitated updates. For instance, the Technical Specifications for Interoperability (TSI) have been replaced by National Technical Specification Notices (NTSNs). GEGN8502 Issue two now includes additional guidance on operations, energy, movement authorities, station and platform design, as well as new guidance on cyber security, stations, remote condition monitoring (RCM), and mobile applications.
