Fundamentals for driveability analyzes in train simulator

Purpose and goal

The aim was to develop a portable solution of the VTI freight train simulator, to make it more accessible, and explore the prerequisites for linking the train simulator with the tools for planning, using the interface to railML. The portable simulator was shown at the project conference. VTI and SWECO have investigated the possibility of connecting VTI train simulators with tools for planning, using the interface to railML. The examination of common methods and an increased understanding of systems provides the foundation for more sustainable innovations and cooperation.

Expected results and effects

The freight train simulator became as accessible and realistic as expected. A first test of mutual interfaces with railML is conducted as well as an evaluation of what needs to be supplemented or changed. At a common standard, the expected effect is that a planned track can easily be tested directly in the train simulator. The actor´s constellation for an upcoming project should be extended to additional railway operators and the ERTMS project. These have been kept informed about the progress and collaboration in a demo project has been discussed.

Planned approach and implementation

To create a portable freight train simulator the interface between the control computer and the driving lever was changed. Both SWECO and VTI have investigated the possibility of making an interface to railML. A sample rail network in railML version 3.0 was used, in which a track between two stations with different signal systems is described. ERTMS worked, while ATC lacks balis information in railML, and consequently information about when to change signals. Sweco has developed a script to convert infrastructure from railML 2.2 / 2.3 to the XML format used in RailSys version 1.0.
