Dynamics tests

Characterization of the dynamic behaviour of railway vehicles on the track for type approval or development purposes.

Tests objectives :

• Establish the dynamic behaviour of new and modified rolling stock or rolling stock whose operating conditions have changed in relation to a particular track, for all types of vehicle (up to 25t/axle) and at all speeds (up to 574.8 km/h)
• Develop and investigate methods for verifying railway dynamics on all European networks

Test facilities :

• Measuring axles for determining the Y, Q and X forces of vehicles under test (with remote transmission of measuring signals)
• Digital measuring chains for data acquisition and processing

Accreditations :

ISO/IEC 17025 awarded by COFRAC

Testing norms :

• Infrastructure TSI and Loc and Pass TSI
• NF EN 14363 – Testing for the acceptance of running characteristics of railway vehicles – Testing of running behaviour and stationary tests
• NF EN 15687 – Testing for the acceptance of running characteristics of freight vehicles with static axle loads higher than 225 kN and up to 250 kN
• NF EN 15686 – Testing for the acceptance of running characteristics of railway vehicles with cant deficiency compensation system and/or vehicles intended to operate with higher cant deficiency than stated in EN 14363:2005, Annex G
• UIC 518 OR – Testing and approval of railway vehicles from the point of view of their dynamic behaviour – Safety – Track fatigue – Ride quality
• UIC 432 OR – Wagons – Running speeds – Technical conditions to be observed

Perform tests in overspeed controlling/monitoring a chosen speed profile and staging points/hold points.

Tests objectives :

• Perfom test by crossing the maximum allowed speed for a rolling stock or an infrastructure
• Record the train cabin environment in audio and video by a camera kit
