Foreword
This document (prEN 12299:2006) has been prepared by Technical Committee CEN/TC 256 “Railway applications”,
the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
This document will supersede ENV 12299:1999.

1 Scope
This European Standard specifies methods for quantifying the effects of car body motions on ride comfort for
passengers and vehicle assessment with respect to ride comfort. The effect considered is:
discomfort, associated with relatively low levels of acceleration and roll velocity.
Other effects, not included in the standard, are associated with higher acceleration levels:
health risk effect: physical damage and psychological deterioration.
The scope of the standard is limited to public railway services; the standard includes railway vehicles designed for
carrying passengers travelling on railway lines, including secondary and suburban lines. However, this standard can
be used as a guide for other railway vehicles, for example locomotives, metros, trams, etc.
The standard applies to passengers in good health.
This standard applies to measurements of motions, but can also be used for simulations.

3 Terms and definitions
3.1 Definitions
For the purposes of this document, the following terms and definitions apply.
3.1.1
passengers
people travelling in a railway vehicle, without specific activities related to the transport
3.1.2
ride comfort
the complex sensation produced during the application of oscillations and/or inertia forces, via whole-body
transmission caused by the railway vehicle’s car body motions
3.1.3
interfaces
the contact parts between the car body or seat and the passenger with the function of sustaining and guiding the
passenger and of transmitting the weight of the same to the car body itself, e.g. floor-feet
