The purpose of this document is to provide methods for quantifying the ride comfort of a passenger in a rail vehicle in response to the track sections it is operated over. The methods aim to quantify the effects of vehicle body motions on ride comfort and to make the assessment of passenger comfort predictable, repeatable, objective and meaningful. The methods and comfort scales are validated for people of good health. This document applies to passengers in rail vehicles operating on heavy rail networks. This document applies to measurements of motions. It also applies to simulated motions. Guidance is provided on: - which method described within the document should be used for different scenarios; - typical values for different comfort levels; - the application of simulation. This document excludes health and safety issues, non-passenger carrying vehicles, vehicle homologation and safety, limit values, motion sickness, discomfort caused by accelerating and braking, design guidelines and measurement technology.

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.).
