Projects always take our measurement technology team to particularly beautiful places. This was also the case recently in Switzerland. The Rhaetian Railway makes railway hearts beat faster. The track is one of the most beautiful in the world, and the Bernina and Albula lines are even UNESCO World Heritage Sites. In addition to the picturesque landscape, the technical requirements are fascinating. Typical for the metre gauge track are curves up to 45 m radius and gradients up to 70 ‰. The Allegra multiple-unit train made by Stadler AG, which is used on this line in various vehicle configurations, is perfectly tailored to these high line requirements. In order to test the running characteristics of different train compositions under special operating conditions, PJM was commissioned with running tests.
The project was carried out in several parts by the experienced system specialist from Austria:

Have a Merry Christmas,
relaxing holidays,
and a great start into 2023!
Precision is the top priority in metrology, and calibration is a crucial factor. To ensure measurement reliability even for projects on site, PJM has developed a mobile calibration test stand. The advantages:
The mobile calibration test stand has already proven its worth during the first "field test" and was used in a project for the Rhaetian Railway. Thus we can react quickly and flexibly to customer requirements even under challenging conditions.

The key data of Plasser & Theurer's 09-3X track tamping machine are impressive: 80 tonnes net weight, 35 m length, 8 axles, and 3-sleeper tamping units ensure powerful and efficient working. To determine the stresses and deformations of the vehicle frame, PJM carried out pressure frame tests according to EN 12663-1. The strength tests were performed at the Linz factory of the technology leader and manufacturer of track maintenance machines. This has clear advantages for the machine manufacturer: the entire on-site infrastructure is used and any adaptations to the object can be coordinated with the design engineers and immediately implemented. Using PJM’s mobile pressure frame allows the tests to be carried out directly in the factory.
Thanks to its modular design, the pressure frame is suitable for every type of vehicle. It has proven its effectiveness in static tests in numerous projects.
"Testing with the mobile pressure frame at the customer's site provides full transparency for the calculation engineers with regard to test procedure. It also greatly facilitates validating the calculation models. This approach ensures the least possible amount of time is spent in projects," explains Martin Joch, CEO of PJM. "PJM handled the measurements very efficiently and professionally. We greatly benefitted from the fact that they were carried out on our premises in Linz," confirms Andreas Pumberger, Head of Railway Testing Lab, Plasser & Theurer.

We are very happe to welcome 3 news colleagues Paul, Marcel and Michael in our measurement technology team! Two new colleagues have already gained insight into our measurement technology & data analysis area in the last few weeks. The third new colleague started in mid-May. The railway industry offers so many interesting specialist areas and future-proof "climate-friendly" jobs - we are pleased that young technicians are finding interest in it.

The unique service portfolio „efficient rail maintenance in three steps” was presented by voestalpine Railway Systems and PJM only last summer. Recently, the first project was successfully completed. Measuring sensors were installed on an existing vehicle of Metro Barcelona, hence the rail measuring was performed automatically. Within a short time, numerous parameters were determined continuously on all metro lines, such as e.g. the quality of the transverse and longitudinal rail profile, the track gauge, and the vertical rail wear. The generated data was digitized and visualized in the form of a network condition report.
Targeted rail maintenance actions were planned, based on the rail measurement results. Subsequently, rails of over 50km of track, including for the first time turnouts, were efficiently milled by voestalpine Track Solutions Germany using its high-performance rail milling technology. After this process, the rails in track and turnouts were restored to an almost as-new condition. The focus lied on eliminating so-called corrugation on the rail running surface. As a result, unwanted noise emissions during subway operation were significantly reduced and travel comfort for passengers was increased. After completing the milling works, a second measurement campaign was carried out in order to demonstrate the effectiveness of rail milling as well as to provide objective evidence of the improved condition.
What are the benefits for the operator of Metro Barcelona? Objective condition data enables efficient and targeted action planning for rail maintenance. In combination with mobile rail milling, identified rail damage can immediately and sustainably be maintained and restored. This reduces unwanted noise emissions, increases travel comfort, and extends the rail service life.
Martin Joch, CEO of PJM, summarizes: “The use of smart measurement technology and the integrated approach to determine rail condition in combination with maintenance measures, enables the operator to significantly increase efficiency in the operation of the infrastructure. Simultaneously, the risk of unplanned maintenance work at short notice is drastically reduced.”
Johannes Wundersamer, Vice President Sales of voestalpine Track Solutions Germany, a subsidiary of voestalpine Railway Systems, says: „With our milling service, operational rail damage in track and turnouts can sustainably be restored. In order to plan this maintenance measure efficiently, it is very important to have the best possible knowledge of the rail condition in advance. With our combined services, including rail measurement technology, we offer an all-round carefree package for our customers.”

PJM's innovation automated brake testing has been evaluated by TÜV and positively approved without further conditions. Hence, it is the first system in Europe meeting all technical and formal criteria and already undergoing widespread operational testing. The system for automatic checking of the wagons’ brakes and semi-automated train preparation is in use on more than 200 SBB Cargo freight wagons and 18 DB Cargo wagons as part of the AmaBPro project. Thanks to its design, it is also possible to expand the brake testing system to include future, safety-relevant applications and automated processes: "Due to the modular concept, our system can be connected with the future DAC with reasonable effort. Whichever European standard will be implemented in 2030, our system will be compatible. Thus, the urgently needed automated brake testing can be rolled out now and not just at the end of the decade," says Günter Petschnig, CEO of PJM.
