RIS-3437-TOM Iss 3

This document sets out requirements to be applied when on-train equipment becomes defective and provides guidance to assist the railway undertakings in the development of contingency plans and alternative controls. It works alongside its Rule Book module, GERT8000-TW5.

Changes in technology, updates to rolling stock standards and the need for clarity in certain topic areas were drivers to revise the standard. The topic areas that have been subject to change are: doors on passenger vehicles, driver’s safety device (DSD) and driver’s vigilance equipment, hot axle box and activations of lineside hot axle box detectors, on-train data recorder (OTDR), sanding equipment to assist train braking, vehicle with locked wheels/wheel flats/shifted tyres/dragging brakes and fire detection and fire suppression systems.

The changes provide greater clarity around the operational response to defects affecting those systems affected by the review. As a consequence, railway undertakings will be able to manage more effectively such occurrences, reducing the operational impact, whilst maintaining or improving the level of safety, saving the industry over £1 million over five years.
