RailSiTe®: Railway Simulation and Testing

The laboratory.

The RailSiTe® is 

DLR‘s rail-specific simulation and testing laboratory. In 2012, the RailSiTe® has been accredited for the functional conformity testing of ETCS on-board units in accordance with DIN EN ISO/IEC 17025:2005. RailSiTe® permits accurate technical and operational simulations, and testing of railway control and safety systems. The complete functional chain of the rail system can be modelled in detail, ranging from trackside control and safety technology to interlocking stations, and from track infrastructure and the air gap between train and track to the on-board systems.

Thanks to its modular architecture, individual control and safety system components can be integrated into the simulation either as software modules or as hardware components, using real physical interfaces. RailSiTe® thus permits the testing of trackside components such as radio block centres, interlockings or field components as well as track infrastructures with regard to their technical-operational functions – either individually or in combination.

RailSiTe® is one of just three independent laboratories in Europe to carry out conformity and interoperability tests of components for the European Train Control System (ETCS). The Institute of Transportation Systems is a certified subcontractor for Eisenbahn Cert (EBC).

At its current level of development, RailSiTe® permits the


  • Validation and functional testing for conformity and

    interoperability of ETCS units at the component level

  • Validation and functional testing of the interaction between on-board and trackside components of the whole ETCS


  • Assessment of the operational suitability of ETCS lines
