This document describes requirements for the structural strength of railway locomotive bodies.

The main purpose of the requirements are to:

  • prescribe the minimum structural integrity level of the vehicle body to ensure safe performance under normal operating conditions and extreme operating conditions;
  • minimize risks to train crew and members of the general public in the event of collisions or derailments.


This Standard applies to new and modified locomotive rolling stock.

This Standard covers the design, construction, and maintenance of rolling stock.

The requirements mandated in this Standard do not retrospectively apply to any existing vehicles other than vehicles which are being modified in areas covered by this Standard so far as reasonably .
