Accredited test center for railway vehicles

Since 2008 we have been accredited according to DIN EN ISO / IEC 17025, confirming our competence in carrying out static and dynamic strength tests on rail vehicles or their components.

In addition to the accredited scope of testing, other testing services are carried out, e.g. tests to gain knowledge or for functional tests.

Our testing services

We provide the following services competently and reliably in our testing center:

  • Structural strength tests on car bodies of locomotives, passenger cars and freight wagons
  • Buffing impact tests on rail vehicles
  • Testing of bogie frames of various designs
  • Testing of draw and buffing gears

Services are provided for the following vehicle categories:
