TrainDy project status on 3 September 2008

The complete system was approved at the meeting of SET 03 on 22 January 2009 and the corresponding certificate was issued. A users’ handbook is available in English. The final report, B177.4/RP 2 “Simulation Program for Longitudinal Dynamics in Trains - Report on the development of the “TRAINDY” simulation program” is expected to be completed by late March 2009.

The dynamic module of the system was approved on 26 June. UIC SET 03 will issue the corresponding certificate. The final section of the project, the GUI (Graphic User Interface) is currently being developed. Work is expected to be completed by the end of the summer.

The system received approval for the dynamic part on 26 June 2008. UIC SET 03 issued the dynamic certificate for TrainDyn.

On 13 December 2007 the first step towards validation was successfully completed when the UIC validation team, under the leadership of Deutsche Bahn AG and consisting of experts from SNCF CIM, Trenitalia DISQS, DB Systemtechnik and ZSSK, issued the certificate for the pneumatic module. This certificate is valid for braking in service as well as emergency braking by venting the brake pipe at one point (driver’s brake valve) at the front of the train. The pneumatic module, which includes a series of tests by FS, two series by DB and three by SNCF, was validated in under three months. In total the rail operators provided 28 experimental data sets (14 for emergency braking and 14 for in-service braking). Regarding the preparation for the test runs, the same parameters were used in all simulations for the pneumatic components (driver’s brake valve, distribution, etc.). The UIC Expert team considered the results for the brake pipes, as well as the brake cylinder, very satisfying. Moreover, standard values were identified for each operator, to be used in the validation process as “good” initial values for the investigations and the assessment of other test runs.
