Brake testing on open line

Measure the braking performance and associated forces for the type approval or development of any kind of rolling stock.

Objectives

Develop, validate and measure braking performance during:
– Tests carried out on a trainset, a convoy or a traction unit
– Slip brake tests on all kinds of rail vehicles
Characterize under normal and degraded wheel/rail adhesion: Emergency brake, service brake, locking brake, parking brake
Determine key parameters: Equivalent response time, jerk, corrected stopping distance, average equivalent deceleration
Monitor related parameters: Pressure in brake cylinders, brake component temperature, axle speed, test conditions (temperature, relative humidity)
Characterize and qualify brake parts
Measure forces applied to the wheels and discs
