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.

Video: Dynamic tests of ČD's passenger coaches

PJM played an important metrological role in the new Viaggio Comfort passenger coaches, which will enrich the fleet of Czech Railways České dráhy and were developed and manufactured by Siemens Mobility.

PJM carried out test runs on the entire Austrian railway network, including high-speed trains on the Westbahn line, in the Alpine terrain in Tyrol and on the Semmering Railway (UNSECO World Heritage Site). The driving behaviour and brakes were tested at 230 km/h or in extremely wintry conditions in the snow.

PJM was also commissioned with the development and production of the measuring wheelsets.

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.

Video: Aerodynamic tests for new nightjet generation of ÖBB

The first journey of the new generation of ÖBB Nightjets is coming soon: from 10 December, the new Generation Viaggio Next Level night coaches will be in service in Austria and Germany. Rail passengers look forward to a wide range of comfort categories and technical innovations.

PJM was commissioned with the overall approval in cooperation with ÖBB. As an accredited test laboratory according to ISO/IEC 17025, the Austrian system specialist was in charge of the design and production of the measuring wheelsets as well as for the approval tests in the areas of running behavior, fatigue strength, acoustics and aerodynamics.

The aerodynamic vehicle tests were performed at speeds of over 200 km/h. In the course of these measurements, compliance with the permissible aerodynamic stresses was checked on the train platform, on the open track and in tunnels. The required boundary conditions in Austria can currently only be realised on the Westbahn line, which is why the test runs took place between Vienna and Linz.

Eco-friendly travelling comfort "Made in Austria"

Austria's railway expertise is reflected in the modern night trains. With the new Nightjets, ÖBB is expanding its role as market leader in the European night train business: Siemens Mobility was responsible for the development, the carriages were manufactured in Vienna and the bogies and wheelsets come from Graz. PJM carried out the approval tests and the measuring wheelsets were designed and manufactured in the headquarters of Graz.

Testing the fatigue strength of a container freight wagon at MFL

The fatigue strength tests are used to check that the rail vehicle can withstand the operational loads. There are different test methods for determining the operational strength, such as static tests or impact tests. An important part of this is the pressure frame test, in which the vehicle frame is subjected to loads in an empty and loaded state. The mobile compression frame has proved particularly effective in this respect. With PJM's own development, it is possible to carry out the tests directly at the manufacturer's premises and to use the infrastructure on site or in the vicinity. This was recently the case at Maschinenfabrik Liezen, which offers a perfect infrastructure. For an Italian wagon manufacturer, fatigue tests according to EN 12663 were carried out with the mobile pressure frame.
