Creating network access tests


Austria, December 2017 to July 2018
Digital Interlocking/CBTC

The project was an important building block for obtaining network approval for vehicles from ÖBB.

Before new vehicle series receive network approval, it is mandatory to carry out test cases at the ÖBB for ETCS Level 1 and Level 2. NEXTRAIL wrote test scenarios for the in-depth suitability testing of the vehicles in conjunction with the track for different vehicle models. If scenarios were already available, they were formally – and, where necessary, also functionally – adapted to the current conditions. In addition, NEXTRAIL supported ÖBB in the coordination of processes. For example, tests had to be designed in such a way that normal operation was not interrupted while also providing reliable testing conditions.
As NEXTRAIL is very familiar with the functionality of the Austrian ETCS system, the tests could be carried out quickly. The requirements of the §40 persons involved were taken into account and their specific knowledge was included in the tests.

Key areas of service

  • Selection of the ETCS Level 1 and 2 test cases carried out for the §40 person

  • Creation of ETCS Level 1 and 2 scenarios

  • Consideration of special vehicle features in the test cases

  • Processing Baseline 2 and Baseline 3 differences for Level 1 and Level 2

  • Creation of scenarios for the transition to intermittent automatic train running control

Special features

Thanks to its wealth of experience in the areas of acceptance tests and functional tests, NEXTRAIL was able to quickly contribute to the registration of a number of vehicle series with the ÖBB. These include TWINDEXX and Talent 3, locomotive X4 VECTRON, EC250/Giruno, ICE-T, Eurodual and Desiro CityJet.
