Now on board: 12 trainees

What's up in summer with PJM? New faces and fresh energy! This summer, 12 trainees will gain insights in our working life and they will support our various teams in the fields of administration, production & measurement, laboratory, hard- and software development and engineering. Welcome on board!

PJM joins symposium “Monitoring Rad-Schiene 2021”

Our CEO Martin Joch is one of the speaking experts on the symposium: “Monitoring Rad-Schiene 2021”. The availability of vehicles is a relevant indicator for railway companies. Martin Joch will present technology and benefits of the autonomous measuring system: “On board monitoring to increase the vehicle’s availability". Comprehensive monitoring of freight wagons creates profound data which is the basis for further decision making such as service and maintenance intervals, damage analysis etc.

The symposium is organised by the Austrian ÖVG and Schuster + Schuster Traffi Infrastructure Consulting and will place on June, 15th in Lower Austria.

Happy Easter!

Have a great start into spring 2021 and Happy Easter!

It’s up to the perfect mix: precision, expertise & flexibility

innofreight is an Austrian specialist for innovative railway transport and logistics systems. When it comes to make the right choice of shock sensors, innofreight counts on PJM’s know-how. Due to our calibrated measurement system, we were able to detect which of the new sensors would be the most precise one. For large-scale projects as well as for smaller projects, it’s always up to precision and expertise. As well as flexibility. We performed the measurements right at the beginning of the new year. 


Measuring turnouts for voestalpine Railway Systems

In its business segments, voestalpine is a globally leading steel and technology group with a unique combination of materials and processing expertise. voestalpine Railway Systems, a subsidiary company of voestalpine AG with approximately 7.000 employees, is the global leader for railway infrastructure system solutions, offering outstanding products, logistics and services for rails, turnouts, signaling and monitoring applications.

In the current project, PJM has performed measurements at the turnouts in Vienna Liesing. The track next to the regional transport hub in the south of Vienna is heavily frequented since train run every 5-10 minutes. By using our measurement data, we determine the stress on the turnouts over a period of two years. Therefore, our team had installed the measurement technology in November 2020. The measurements are performed fully automated. The data will be transmitted to the PJM servers via mobile network. Parallel to this, data analysis will run over the next 24 months.


Mercer & TRANSWAGGON rely on our automated load monitoring system

Mercer is a full-service-provider for timber industry and wood owners. The portfolio of the German, innovative company comprises pulp mills and a saw mill in Germany. Hence, these figures clearly show Mercer's relevance on the European continent: Every year, Mercer purchases over 7 million bank meters of wood, among it 5 million round timber. Over 3,5 million tons of wood are transported by rail. All in all that's over 2.000 block trains per year. 

Thus, Mercer Holz is one of the biggest wooden rail logistic providers in Europe. Wood is a very valuable raw material yet "difficult" for transporters. "Due to the different density and moisture, wood can differ in weight by up to 50%", says Jürgen Köhler, Head of Logistics at Mercer Holz GmbH. This is a great uncertainty factor having a significant impact on logistics: cost-effectiveness, security and error frequency. A perfect solution is the LoadMonitor-system by PJM. In addition to important data acquisition in real time via general monitoring functions, the LoadMonitor-system provided an automated loading process. "We need reliable, stable wagons and loading security - for both shipping companies and customers", summarizes Jürgen Köhler. Now. Mercer Holz has closed the gaps in the logistics process chain with the LoadMonitor. All essential information about freight wagons as well as an automatic loading control on site are covered by just one system.

Lothar Krebs, Deputy Sales Manager of TRANSWAGGON GmbH in Hamburg, brings a different perspective from the wagon keeper's point of view. "For our customers, a big issue is when vehicles are stopped or removed from the track. That costs time and money. His experience with the LoadMonitor-system: "The use of capacity has increased a lot. It's a great benefit that the loader can immediately see whether the wagon is overloaded or not". His conclusio: "The cooperation worked very well, as did the implementation of the PJM-system and the entire project management. The system runs very smoothly". He prognoses: "Digitalising rail freight is fundamentally correct and must be the future.”

Powerful measurement: Impact tests for Innofreight’s double container wagon

Physics is a defining factor in our everyday life. Recently, we determined the longitudinal forces and longitudinal acceleration of an 2x 30ft. InnoWaggon of Innofreight. Therefore, the measurements were performed with three different container types: An InnoTainer Coils, a RockTainer and a SlurryTainer to carry so-called lime milk. Lime milk is a mixture of marble, chalk and water used as filling medium and coating pigment in the paper industry. To go into detail, PJM was in charge to measure the force effects on the bumpers, the strength development in the pull rod and in the adapted longitudinal stops of the brackets. The impact tests were performed in Styria.

Innofreight provides innovative, patented rail freight cargo and logistic systems. Among other things, Innofreight is specialised on developing and advancing freight wagons.

Austria’s VCÖ Mobility Award 2020 for WaggonTracker!

Our WaggonTracker-system was awarded with the Austrian Mobility Prize 2020 in the category "digitalisation". Federal minister Leonore Gewessler, ÖBB director Michaela Huber, Siemens Mobility CEO Arnulf Wolfram and VCÖ-CEO Willi Nowak presented the award to PJM-CEO Günter Petschnig.

The 59 members of the jury found: "We just realized that a digital system is not standard in rail freight transport. Thus, it is a big step to achieve a competitive position between road haulage and rail freight cargo. It is an innovation that was past overdue and which has great potential. A comprehensive data set is the basisfor modernisation and optimisation."

The top-class event was started with a talk of experts: Federal minister Rudolf Anschober and the guests mentioned above presented future concepts and projects. The event was hostest by TV-moderator Corinna Milborn.

VCÖ Mobility Award 2020

The Mobility Award 2020 presented by VCÖ is Austria's greatest competition for sustainable rail freight cargo and climate compatibility. Further information on

Load measurement for industrial shredders by UNTHA

UNTHA is a well-known company specialised to design and construct industrial shredders. The areas of application range from recycling of waste wood and organic waste to many more recyclable materials. To shredder various types of metal, it needs high-performance shredders. When it comes to measure the strains and stresses of the shredder machines, UNTHA has counted on the know-how of PJM for various times. Recently, PJM had tested the metal shredder machines with 2 and 4 shafts. During the test phase, the torsional vibrations are tested while shredding different types of material. For long-term measurement, the test phase may take several weeks. The measurements of each shaft provide crucial results finding their way into further developments of the machines, e.g. to determine the level of motorisation.

The great challenge in measuring shredder machines is to link the contrast: The shredder process is very rough, yet the very sensitive devices must provide precise and reliable data.


Shredded material is the basis for reusing and recycling which is a crucial contribution to protect the environment protection and conservation of resources. We are proud of being part of this contribution!
