Heavy rail / Urban light rail

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
