The new Koralm Tunnel is here! PJM was already in action for test and measurement runs.

December 12 is a big day: the Koralm Tunnel is officially open, bringing Graz and Klagenfurt much closer together! We congratulate everyone involved on this milestone, which will strengthen Austria's position in international freight and passenger transport in the long term.

We have also already been in action in the tunnel: our team carried out important test and measurement runs in advance to collect essential data for technical conformity and approval. The video provides a brief insight into this.

We are delighted to have been part of the success story of this high-performance corridor and look forward to our future assignments on this extraordinary route!

IRSA Aachen: Focus on infrastructure and digitalization

The 5th International Railway Symposium Aachen (IRSA) took place from November 19 to 20. The renowned forum, which brought together around 250 international experts, focused on the effects of climate change and the mobility transition on the rail system.

Matthias Zelinka (PJ Messtechnik) enriched the discussion with an exciting presentation on a simulation model for the interaction between pantographs and overhead lines.

VPI Vienna: Freight transport of the future

At the same time, an information event organized by VPI Austria (an Association of Private Freight Wagon Interested Parties) in Vienna also addressed the challenges in rail transport and logistics.

For almost 100 participants from Austria and abroad, there were numerous presentations, one of which was given by Günter Petschnig (CEO PJ Monitoring). He showed how digital train functions enhance rail freight’s safety and cost-effictiveness, attractiveness and sustainability.

INFRATRACK – a new company in the PJM Group

PJM und Boom Software utilising the connecting railway of a decommissioned coal-fired power station as a test site for innovations in the rail industry. This purpose has led to the foundation of the joint venture INFRATRACK Solutions.

The two railway specialists Boom Software AG and PJ Messtechnik GmbH have taken over the connecting railway line at the Mellach Verbund power plant site. This cooperation will allow the existing rail infrastructure of the decommissioned coal-fired power plant to be used more intensively, particularly for testing purposes.

Located in the immediate vicinity of Graz and the new Koralmbahn railway line, as well as the two Styrian companies, the site will be home to innovations and further developments in the railway sector, particularly in the fields of measurement and testing technology and software.

The optimally located and equipped connecting railway line provides an ideal environment for testing rail vehicles and components. The range of activities extends from physical asset inspections to sensor- and software-based testing.
