GMRT2173 Iss 4
Size of Vehicles and Position of Equipment
This document sets out Great Britain (GB) requirements in scope of National Technical Rules for the methods of determining the swept envelope of rail vehicles. It includes specific gauge requirements for the lower sector and specific items of equipment on the rolling stock, and minimum requirements for the recording of vehicle gauging data.
Summary Of Changes
The document was updated for clauses to be presented in the current format of requirement, rationale and guidance. Requirements that were not National Technical Rules (NTRs) were transferred to other documents.
The maximum vehicle overhang length was increased to align with the value set out in the National Technical Specification Notices (NTSNs).
Informative appendices for RSSB Research Projects T1196 – Development of a Suite of Pantograph Gauges and T1109 – Freight Bogie Suspension Gauging have been included.
