New service jet from Stadler for ÖBB: Test runs and instrumented wheel sets for the new rescue train provided by PJM

ÖBB-Infrastruktur AG has procured a new fleet of rescue trains with 18 new service jets from Stadler.

The low-emission and multifunctional vehicles will be in operation throughout Austria, travelling at speeds of up to 160 km/h. PJM was commissioned as an accredited test center in accordance with ISO/IEC 17025 for the test runs. The dynamic tests are being carried out in coperation with the ÖBB mechanical measurement group. PJM was also responsible for the production and development of the instrumented wheelsets. The vehicle tests for the areas of running behavior, brakes, acoustics and pantograph will take place throughout Austria and are expected to
be completed in autumn 2024. For unrestricted track access in Austria, running dynamic tests were carried out in track sections 5c, for vehicle authorization for radius curves down to 100 metres.

„The instrumented wheelsets were specially developed and manufactured for these requirements in very tight curves.Our wheelsets have proven themselves in the dynamic track tests,“ says Martin Joch, CEO of PJ Messtechnik GmbH. The new generation of service jets required some innovations in the test runs. „Due to the new standard, these demanding tests were carried out on the ÖBB network for the first time. The results of the test runs are extremely precise and reliable and form a solid basis for evaluating the rail vehicle,” says test manager Roman Schmid, ÖBB Produktion GmbH.

The new service jets are designed for a wide range of applications. For example, they are equipped with modern firefighting equipment to carry out rescue and extinguishing work in the event of a fire. They can also tow trains or carry out maintenance work.
