This European Standard describes a general algorithm that may be used in all types of high speedand conventional vehicle applications, including self-propelling thermal or electric trains, thermal orelectric traction units; passenger carriages, mobile railway infrastructure construction andmaintenance equipment and freight wagons. This standard does not specify the performancerequirements. It enables the calculation of the various aspects of the performance: stopping orslowing distances, dissipated energy, force calculations and immobilization braking.This standard enables the verification by calculation of the stopping, slowing and immobilizationperformance requirements for high speed and conventional trains operating on high speed andconventional infrastructure.This standard presents:a) example of distance and other dynamic calculations, see Annex C;b) example of immobilisation calculations, see Annex D.
