RIS-7707-INS Iss 1

This document sets out requirements and guidance for new, renewed, and upgraded switches and crossings (S&C) to provide for identification and safe operation.

The requirements are additional to those set out in the Infrastructure (INF) National Technical Specification Notice (NTSN) and National Technical Rules (NTR) set out in GCRT5021. As these requirements do not meet the criteria for NTR as set out in the Railway Group Standards (RGS) Code and relevant legislation, they are included in this Rail Industry Standard (RIS).

29/05/2025 - At its meeting in May 2025, INS SC approved the recommendation that no further action is required.
