Railcar brake system testing determines the braking performance of railway vehicles. Braking performance is assessed by determining stopping distances or equivalent deceleration under load. Test integration includes speed, load, stopping motion, temperature, air pressure and systems control.

Clark’s structures lab has the infrastructure and fixturing to simulate the mechanical performance and environmental conditions of railcar braking systems. The dyno lab at Clark Testing can conduct brake testing with variable torque, load and speed (RPM). Custom design test profiles can simulate stop, stop/start and dwell under load.

All testing is conducted under the guidance of Clark’s ISO 17025-2017 quality assurance program ensuring the calibration, validity and quality of test data provided.

We also conduct Mag particle and dye penetrant analysis to assess crack propagation due to the effects of load testing the truck frame, bolster & bogey.

The structural lab at Clark Testing includes modular load frames and a 30’ X 90’ structures floor with mechanical tie-down clamps on a 48” centerline grid pattern for 1.5 million lb. static and dynamic load capacity.
