Stronger together: PJM and Ingenieurbüro Rörden combine their expertise and found EMC Rail Services

Two industry experts are joining forces: Ingenieurbüro Rörden and PJM have launched the subsidiary EMC Rail Services GmbH. The German company is a specialist in EMC testing in the rail sector, and the Austrian company PJ Messtechnik is an established testing centre for rail vehicles. Now, they have bundled their expertise and thus create an even more powerful testing service. The focus of the newly founded EMC Rail Services are EMC measurements (electromagnetic compatibility).

EMC tests ensure that electrical and electronic systems work without interference both in the vehicle (e.g. locomotive, wagon) and with the infrastructure (e.g. level crossing system, railway radio, signalling). This ensures that no unauthorized electromagnetic interference occurs and that the systems are protected from external influences.

Safety and operational reliability have top priority in rail operations. Electromagnetic interference must never trigger false signals or lead to the failure of critical systems such as brakes. At the same time, modern rail systems are becoming increasingly complex and electronic. As a result, electromagnetic compatibility (EMC) is becoming increasingly important - and with it the need for testing services.

This is where EMC Rail Services provides its services: Ingenieurbüro Rörden GmbH, based in Dortmund (Germany), is an ISO/IEC 17025 accredited test centre and has extensive expertise in measurement technology, approval support and technical testing in the field of electromagnetic compatibility (EMC). PJ Messtechnik GmbH, based in Graz (AT), is an accredited test centre confirmed by ISO/IEC 17025 standard for brake tests, vehicle dynamics, fatigue strength, aerodynamics, acoustics and pantographs.

The partnership allows two testing laboratories to combine their service portfolios and pool expertise and resources, thus creating a clear advantage for customers. The focus is on the Austrian market as well as the neighbouring countries to the south and east. The new company's testing services include:

Radiated electromagnetic disturbances
Radio protection
Human exposure
Compatibility with track circuits
Compatibility with axle counters / sensors

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.
