Rolling stock weighing procedures

Characterizing vehicle loads for type approval or an expert assessment purposes thus ensuring safety against derailment.

Tests objectives

  • Determine the static load at each wheel, the centre of gravity and the unloading rate for all types of vehicle (for type approval, modification, renovation or expert assessment of a vehicle)
  • Two types of weighing:
    – Weighing in compliance with NF F00-701
    – Weighing performed on maintenance, construction or vehicle maintenance sites

Tests facilities

  • Load cells (10,000 or 20,000 daN)
  • Topographical viewfinder to ensure wheel levelling
  • Weighing frame with lifting equipment
  • Movable frame that can be installed on track


ISO/IEC 17025 awarded by COFRAC

Testing norms

NF F00-701 – Measurement of the static loads per each wheel of the vehicles – Weighing installations and control

NF EN 14363 – Testing for the acceptance of running characteristics of railway vehicles – Testing of running behaviour and stationary tests
