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.

TRANSWAGGON includes automatic brake testing and digital monitoring as equipment option

Together with PJM, the TRANSWAGGON Group is making a key contribution to the automation and digitalization of rail freight transport in Europe. Wagon rental customers save time and increase safety in operation by equipping their wagons with automatic brake testing. Many other digital monitoring features are available for TRANSWAGGON customers. In addition, the energy self-sufficient and powerful WaggonTracker system can be expanded with customer-specific systems. The integration of automatic brake testing and monitoring functions into the TRANSWAGGON Group's equipment portfolio is a logical step.

"The automatic brake test saves time and increases safety during operation. It eliminates the need for a  time-consuming walk around the entire train. Train preparation can therefore be carried out more quickly and safely," says Bertram Wieloch, CTO and member of the TRANSWAGGON Group's Executive Board.

This is not the first cooperation between the TRANSWAGGON Group and the Austrian system specialist PJM. In the past, around 500 wagons were equipped with the so called LoadMonitor, an automatic load weight monitoring system, on behalf of Mercer Holz. The system analyses the load weight during the loading process and visually indicates the maximum load capacity. Since then, one of Europe's largest timber logistics companies has benefited from a better capacity utilization, avoids overloading thanks to the precise data and appreciates completely paperless documentation.

FS Logistics Business Unit continues fleet upgrade with PJM’s smart train portfolio

Combining transport efficiency with safety is an important requirement for Mercitalia Intermodal in daily intermodal transport. The Italian wagon operator has therefore been focusing on digital monitoring functionalities and automated processes for several years. The transformation of the existing fleet into Smart Train freight wagons is being systematically implemented. This year, at least another 180 wagons will be modernized, while around 200 wagons - mainly of the T3000 type - have been upgraded in the past two years. Mercitalia Intermodal began upgrading its freight wagon fleet back in 2017.

The benefits of the Smart Train functions are far-reaching: shorter delivery times thanks to automated processes in the track environment, predictive maintenance logic and condition-based maintenance models reduce costs while increasing reliability, efficiency and the general safety of rail transport.
