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.

Analyst Certification of the American AAR WABL Committee for PJM strength calculations

PJM now also offers wheelset expertise for the leading rail freight country, the USA. The AAR WABL Committee (Association of American Railroads) has voted to approve PJM for performing strength calculations of wheels according to the S-660 and S-669 standards. This new area of expertise is also already in use on a project. "We are very pleased that we can now also offer our customers this consultancy service for the use of rail vehicles in North America," explains Martin Joch.

In the field of wheelsets, PJM has built up profound know-how over the years. Here, too, the link between calculation and testing plays a major role. The expertise includes calculations as well as the design of instrumented wheelsets.
