scope:

This document describes the functionality, position, constraints and operation of an magnetic track brake system (MTB system) installed in bogies for use in emergency and in low adhesion condition on Mainline Trains up to speeds of 280 km/h. It does therefore cover high suspension types of MTB only and not high/low and low suspension type of MTB. This document also contains test methods and acceptance criteria for a MTB system. It identifies interfaces with electrical equipment, bogie, track and other brake systems. On the basis of the existing international and national standards, additional requirements have been defined for: . conditions of application for the MTB; . retardation and brake forces; . functional and design features; . strength requirements; . type, series and vehicle implementation tests. For design and calculation an "imaginary surface" was established.
