PJM has established a new test area and has been accredited for pantographs
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.

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.
In the coming weeks, the measurement technology team will be testing another rail vehicle in single and multiple-unit operations.
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.
A total of 6 specialist areas are accredited: running characteristics, strength, brake, acoustics, aerodynamics and pantograph. In combination with comprehensive expertise in engineering and in the development and production of instrumented wheelsets, PJM has established itself as a reliable partner in the testing of rail vehicles all over the world and in the handling of overall rail vehicle testing. ‘We have the size, expertise, stability and infrastructure to carry out rail vehicle projects worldwide,’ says Martin Joch.
