prEN 14363-4

Scope

This document applies to all rail vehicles including OTM’s and Road-rail machines, which are operated on the heavy rail network with standard track gauge 1 435 mm and nominal static vertical wheelset forces up to 350 kN. This document may also be applicable (partly or in full) to: — rail systems with different track layout, e.g. urban rail systems and/or, — rail systems with other than 1 435 mm nominal track gauge. Note: For such rail systems other than 1 435 mm track gauge or urban rail systems, the related post analysis, limit values and test conditions could be different. They are specified nationally taking into account track design and operating conditions. This document contains a method to assess the dynamic behaviour of rail vehicles by on-track testing, including simplifications for special vehicles and for extension of the field of application based on similarities, applicable to vehicles which: — are newly developed; — have had relevant design modifications; or — have changes in their operating conditions. The following items are not handled by this document: — the strength of the vehicle and the strength of mounted parts, — passengers and train crew vibration exposure, — ride comfort, — load security and, — effects of cross wind.
