Expanding headquarters: New hall for instrumented wheelsets

The instrumented wheelset expertise is made up of several elements that PJM combines with each other. PJM perfectly matches measurement technology, experience as an ISO/IEC 17025 accredited test centre, engineering expertise and 10 years of experience in the development and production of measuring wheelsets.

PJM has now also raised its infrastructure and technical equipment to a new level. The new part of the building has been equipped with a comprehensive range of equipment to ensure the highest levels of precision, stability and standard in metrological terms. In addition, the expanded infrastructure will enable even faster throughput times and project processing in future. The equipment includes, among other things

  • Mobile test rig for measuring wheelsets for all track gauges and calibration during test runs on site
  • Premises for the parallel production of 12 instrumented wheel sets
  • Indoor crane and two electric forklifts
  • ESD-protected working environment
  • Air-conditioned room (for consistently ideal conditions, for example when attaching strain gauges)
  • Dynamic test rig for end-of-line testing of instrumented wheel sets
  • Fine balancing in accordance with ISO13260 limits

The dovetailing of theory with practical testing experience is a great added value for our customers,’ says Martin Joch. He continues: ‘The instrumented wheelset infrastructure guarantees the highest measurement quality for every phase and every requirement. In combination with our specialised knowledge in engineering and our many years of experience in dynamic testing, we offer vehicle manufacturers a considerable portfolio of knowledge and services.’

This makes PJM a strong partner in the field of measuring wheelsets:

  • All processes and project steps relating to measuring wheelsets are handled by PJM in-house and from a single source
  • This also results in short throughput times
  • Calculation, design, production, calibration and balancing
  • Powerful telemetry system: Thanks to the extensive equipment, 12 measuring wheelsets can be operated simultaneously
  • PJM offers solutions for every application and every wheel geometry (not just standard solutions)



State Prize for Digitalisation 2023 for PJM

A railway project was honoured with the Austrian State Prize for Digitalisation 2023. The automatic brake testing system from PJM emerged as the winner in the ‘Digital Transformation and Innovation’ category. State Secretary Claudia Plakolm and Harald Kräuter, ORF Director of Technology and Innovation, presented the award to CEO Günter Petschnig and COO Christoph Lorenzutti from PJ Monitoring GmbH.

 ‘We are delighted to receive this award for two reasons. The fact that a rail project was honored underlines the importance of rail freight transport in an economic and climate policy context. 10 years of development work, high investments and perseverance have been rewarded. This is great recognition for our entire team,’ says Günter Petschnig. He adds: ‘SBB Cargo is a great development partner. Such complex projects can only be successfully completed if all project partners pull together. A big thank you for the commitment, the belief in the technology and the great collaboration.

Press release 

The quality of the projects awarded this year as part of the State Prize for Digitalisation is impressive. You can see how much innovative strength there is in Austria in this core area, which is crucial for a successful future. I am delighted that we have been able to bring some particularly outstanding ideas to the fore with today's awards. On behalf of ORF, I would like to congratulate all of the award winners,’ emphasised Harald Kräuter, ORF Director of Technology and Innovation.

The jury of experts evaluated the open-topic submissions according to a catalogue of criteria such as degree of innovation, quality of implementation, high usability, added value for users and market potential. The submission phase was organized by the FFG (Austrian Research Promotion Agency). The jury's statement: ‘The submission Digital Rail Transport - Automated Brake Test enables the digitalization of the previously manual inspection of brakes in rail transport using special sensor technology and remote evaluation via mobile operating devices. This reduces the manual effort and duration of the brake test. By automating this inspection process, the physical strain on staff and the time required for the inspection are reduced. This means that the rolling stock can be put back into service more quickly and enables rail transport capacities to be increased. This patented system has already been approved and is being used successfully by the SBB Cargo.’


Staatspreis für Digitalisierung 2024


The State Prize for Digitalisation shows that Austria is a strong location for digital innovations. We must continue to develop our qualities in a targeted manner and, above all, further strengthen digital skills throughout Austria. They are an important basis for successful digital transformation and innovative companies. I would like to congratulate all the award winners who are making new digital success stories possible for the whole of Austria and are attractive role models for other companies and institutions,’ said State Secretary for Digitalisation Claudia Plakolm.

Digitalisation is a decisive factor for growth and broad prosperity, which we must use in a targeted manner in Austria. Openness to technology is the indispensable basis for innovations that secure our competitiveness and thus our entire way of life. I am impressed by the achievements of the award winners and congratulate them warmly. Because they tackle and implement - that is the right spirit for the future,’ said a delighted Federal Chancellor Karl Nehammer.
