The railway specific laboratory offers the opportunity to analyze systems, subsystems and components of train control technology as well as operational concepts. The validation of the interoperation between system components from different suppliers is possible from a functional and a safety related view.

Due to its modular design, the flexibility and expandability of the laboratory is ensured so that hardware-in-the-loop and cross-reference tests can be performed next to sheer software simulations.

With the certification as “Subcontractor of the Notified Body Interoperability” by EISENBAHN-CERT (EBC), the institute operates an internationally accredited European railway test laboratory.


RailSiTe covers the whole chain reaching from the interlocking operator, tracks and train dynamics, the train control systems up to the train driver. The currently implemented technology is based on ERTMS/ETCS (European Rail Traffic Management System/European Train Control System).

RailSiTe is at present composed of the following simulated components which can be replaced by industrial components if required:

  • ­Interlocking, Radio Block Center
  • ­Eurobalise, Euroloop and Euroradio transmission
  • ­Train dynamics and odometry
  • ­Train control systems

RailSiTe is supplemented by a 2D visualization of the driver‘s perspective as well as a stereoscopic 3D visualization by the connection to the Virtual Reality Laboratory.

Furthermore a realistic driver’s cabin and a real level crossing are integrated into the laboratory. The connection to other infrastructures available at the institute is also possible (e.g. the movement platform of the dynamic car driving simulator).

Fields of Application

The primary application of RailSiTe arises from the institute’s research and development activities regarding railway operation and technology. Furthermore, RailSiTe is used to validate components, systems and subsystems. Conformity and interoperability tests (e.g. for ETCS) can be performed as well.

Another application is the operational validation of various equipment and operation variants. Due to the multi disciplinary orientation of the institute, research projects from the fields of ergonomics and human factors can also be done.
