New service jet from Stadler for ÖBB: Dynamic tests and instrumented wheelsets

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 co-operation 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 pantographs will take place throughout Austria and are expected to be completed in autumn 2024. For unrestricted track access in Austria, the test runs were carried out in test zone 5c, for vehicle authorization for radius curves down to 100 meters. "The instrumented wheelsets were specially developed and manufactured for these specifications in very tight curves. Our wheelsets have proven themselves in the dynamic 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 standards, 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.

Expanding headquarters: New hall for instrumented wheelsets

The instrumented wheelset expertise is made up of several elements that PJM combines with each other. PJM perfectly matches measurement technology, experience as an ISO/IEC 17025 accredited test centre, engineering expertise and 10 years of experience in the development and production of measuring wheelsets.

PJM has now also raised its infrastructure and technical equipment to a new level. The new part of the building has been equipped with a comprehensive range of equipment to ensure the highest levels of precision, stability and standard in metrological terms. In addition, the expanded infrastructure will enable even faster throughput times and project processing in future. The equipment includes, among other things

  • Mobile test rig for measuring wheelsets for all track gauges and calibration during test runs on site
  • Premises for the parallel production of 12 instrumented wheel sets
  • Indoor crane and two electric forklifts
  • ESD-protected working environment
  • Air-conditioned room (for consistently ideal conditions, for example when attaching strain gauges)
  • Dynamic test rig for end-of-line testing of instrumented wheel sets
  • Fine balancing in accordance with ISO13260 limits

The dovetailing of theory with practical testing experience is a great added value for our customers,’ says Martin Joch. He continues: ‘The instrumented wheelset infrastructure guarantees the highest measurement quality for every phase and every requirement. In combination with our specialised knowledge in engineering and our many years of experience in dynamic testing, we offer vehicle manufacturers a considerable portfolio of knowledge and services.’

This makes PJM a strong partner in the field of measuring wheelsets:

  • All processes and project steps relating to measuring wheelsets are handled by PJM in-house and from a single source
  • This also results in short throughput times
  • Calculation, design, production, calibration and balancing
  • Powerful telemetry system: Thanks to the extensive equipment, 12 measuring wheelsets can be operated simultaneously
  • PJM offers solutions for every application and every wheel geometry (not just standard solutions)
