prEN 13749

This document specifies the requirements for the validation of the structural integrity for the following running gear structural components:
- Components in the load path between the track and the car body (e.g. bogie frame, axlebox, or other equivalent components) and
- Components that are in the traction and braking load paths without secondary retention.
The following components are excluded from the scope of this document:
- Structural components that are rigidly attached to the car body (e.g. bolsters directly attached to the car body or connected via slewing rings, centre pivots, etc.);
- Equipment structures (e.g. traction motor housings, gearbox housings, and brake units), including components that are rigidly attached to them, that are not in the load path between the track and the car body;
- Components for which the structural integrity validation requirements are regulated by other specific EN standards (e.g. wheels, axles, brake discs, bearings, coil springs etc.);
- Suspension components including springs, dampers, elastic elements and their connecting elements;
- Revolving components (e.g. drive train components etc.).
