Center buffer coupling test stands

With this test stand, a wide variety of rail couplings can be tested in manual or automatic test runs:

  • Coupling and uncoupling procedures
  • Dynamic push and pull studies
  • Mountain crossings and cornerings
  • Leak tests

Equipped with the real-time automation system for test benches RENK I RDDS, this test bench is ideally suited to support the development of analog and digital central buffer couplings with realistic mechanical and electrical tests.
