PJM tested MPV®-VentuS® of WINDHOFF

WINDHOFF relied on PJM's experience and expertise to test an innovative, modular multi-purpose vehicle within a short time frame.

The German specialist for rail vehicles, railway and shunting technology has developed the next generation of a multi-purpose vehicle. WINDHOFF Bahn- und Anlagentechnik GmbH had commissioned the Austrian system specialist PJM to carry out the test runs for approval on the German rail network. As an accredited test center in accordance with ISO/IEC 17025, PJM carried out vehicle tests in the areas of braking and running characteristics as well as static tests to determine derailment safety and wheelset torsional vibrations.

MPV®-VentuS® is a modular system that can be used to create a wide variety of vehicle configurations. The range of working modules includes various cranes, platforms, contact wire pusher, but also containers or contact wire measuring systems. The power system also has a modular design so that adjustments can be made very easily over the course of the vehicle's service life and, for example, a vehicle that is currently diesel-electric with a generator and electric motor can be converted to all-electric at a later date. The MPV®-VentuS® vehicle family is designed on the basis of DIN EN 14033 and auhtorized with the European TSI homologation. The MPV®-VentuS® type GAF, which was tested together with PJM in Austria last year, is a track maintenance vehicle for Deutsche Bahn (DB). The vehicle was officially presented at InnoTrans 2024, and in February 2025 Windhoff and DB received authorisation to place the MPV VenuS GAF modular ancillary vehicle on the market. The vehicle is approved on the basis of the European TSI from the 4th railway package.

‘It is important to us, to complete our customers’ projects just in time and successfully. For WINDHOFF too, we were able to carry out the vehicle tests and analyses within a short time frame,’ says Martin Joch, CEO of PJ Messtechnik GmbH.

New test area: PJM accredited for pantograph

PJM has expanded its scope as an accredited test center in accordance with ISO/IEC 17025 and now also tests the dynamic interaction between pantograph and overhead contact line. In addition to measurements in accordance with EN 50317, the accreditation also includes simulations in accordance with EN 50318, making PJM the only company in Austria with accreditation for the specialist area of pantographs.

Over the past two years, the Austrian system specialist has invested in the infrastructure of the new department. The pantograph test rig for calibrating the measuring system - as well as the technical equipment for other areas - has been set up at the company's site in Graz. Extensive tests in the wind tunnel have proven that the measuring system is non-reactive. With the existing measuring equipment, tests can be carried out with up to two measuring pantographs, which means that multiple-unit operations can also be realised. The requirements for the interaction between pantographs and the overhead contact line system of the new service jet for ÖBB had been tested in summer (as announced in the media release: https://pjm.co.at/wp-content/uploads/2024/06/PI-PJM-Servicejet-6-2024-DE-Web2.pdf). In the coming weeks, the measurement technology team will be testing another rail vehicle in single and multiple-unit operations.

‘Due to decarbonisation, the focus will be on electric rail vehicles in the future. With its corresponding expertise and infrastructure, PJM is ideally positioned for the new specialist area,’ says Martin Joch, CEO of PJ Messtechnik GmbH. With the new specialist area, PJM offers several advantages for clients, such as the efficient sequence of the various tests for rail vehicles. The expertise in the area of simulations offers particular added value: ‘Simulations significantly minimise the testing effort for multiple tractions. Theoretical calculations allow the large number of variants to be reduced to relevant train combinations, which are then tested in dynamic track tests. This saves valuable time and reduces costs,’ says Martin Joch.

InnoTrans 2024: For the first time, PJM is presented with 4 companies

PJM will be presenting itself four times at this year's industry highlight. PJ Messtechnik, PJ Monitoring, PJ Motion and RCC will be represented with their areas of expertise.

With these 4 business areas, PJM is now a strong partner throughout the entire life cycle of a rail vehicle and can take on all tasks relating to the authorization of rail vehicles. The range of services includes consulting from the initial idea and authorization management by PJ Motion, engineering and vehicle testing by PJ Messtechnik, and the portfolio as an accredited inspection body by RCC. The portfolio is supplemented by digital applications for goods trains such as automatic brake testing or the most comprehensive smart train functions currently available in the freight wagon sector. ‘Through organic, sustainable growth and the consistent expansion of infrastructure and specialist areas, PJM has firmly established in the rail industry. This is reflected, among other things, in the fact that larger project volumes are being commissioned in the area of vehicle testing and engineering,’ says Martin Joch, CEO of PJ Messtechnik.

The automatic brake testing and smart train functionalities provided by PJ Monitoring are attractive applications in the freight wagon sector: ‘Our brake testing system is of great interest to large rail transport companies, smaller private railways and also wagon keepers, as it solves several key problems. Train preparation is shortened and the shortage of skilled labor as well as increasing costs due to higher personnel expenses and inflation are significantly cushioned. The system saves time and money and creates efficiency - all of which is urgently needed in rail transport,’ says Günter Petschnig, CEO of PJ Monitoring.

PJ Motion is the youngest company in the PJM group, but has already established itself as a renowned partner after just one year, particularly in authorization management. ‘The focus of our projects is clearly on authorization management. Our expertise in the 4th railway package is in hight demand because we can reduce complexity and provide objective decision-making support in terms of technical and economic challenges,’ says Thomas Hofer, CEO of PJ Motion.

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.
