Blockchain for increased safety

Blockchain is known for being applied in the context of cryptocurrencies. Beyond that, “Distributed Ledger Technologies” that record transactions in a complete, correct, timely, and orderly manner offer other fascinating application scenarios.

Radar: the "eye" of the machine

The word “radar” may make you think of air travel and parking assistants. But radars have also entered the field of railway, specifically in the form of ground penetrating radar (GPR), also known as georadar.

Research developments for the urban rail

Traffic in tram, light rail and metro networks causes a variety of damage to the rail head. Mechanical stress results in scoring, corrugations, waves, and much more. For decades, preventive, or at least regular, rail grinding has been considered an effective countermeasure.

How do the Dynamic Track Stabiliser and ballast interact with one another?

Does the Dynamic Track Stabiliser (DTS) have the potential to be more than a ballast compacting machine? Could it also be a measuring device for monitoring ballast compaction? An ongoing research project conducted by the Vienna University of Technology (TU Wien) is examining these questions.

Artificial intelligence for more efficient ground-penetrating radar analysis

Ground-penetrating radars measure the condition of track substructure. However, the analysis of this data is very time-consuming. Could the use of AI reduce this effort? Plasser & Theurer is part of a research group that took on the challenge of answering this question. They discovered that, among other things, a clever application of filters facilitates the analysis.

Tamping tine and ballast: teaming up

Thanks to a brand new measurement and analysis method, it is now possible for the first time to observe the movement behaviour of ballast throughout the entire tamping process. In addition, the method provides an unprecedented level of detailed insight into the ballast condition. The tamping tine is particularly important here: the new method allows it to function as both a working and measurement tool.

WCRR 2019 Tokyo: On the state of the art

1994 marks the birth of the WCRR. Held in Paris, it was initiated by several major railway companies. Ever since, the world’s probably most important railway expert convention has been travelling around the globe. In 2019, it pitched its tents in Tokyo for the second time. Over 1,000 participants, 630 submitted research papers and around 300 presentations in just 4 days: the variety of topics is as remarkable as the in-depth expertise presented.

Absolute track measurement

One of the tasks of the permanent way staff of the Italian railway network (RFI, Rete Ferroviaria Italiana) is checking the absolute track geometry. This ensures that the geometric quality of the track meets the increasing speed. RFI has introduced new control techniques over the last few years to make this work easier and faster.

Deep learning units for the automatic turnout tamping assistant

Machines that attend school? What might sound like science fiction, has become a reality at Plasser & Theurer. Our development team is working on a 3D scan based sensor system, training it to take autonomous decisions. The method applied: deep learning.

Function test well before applying the first weld seam

For testing the control system embedded in a machine, you need no longer wait for the machine to be built. Thanks to the Hardware in the Loop method, you can start with the first function tests directly after design is completed.

Dynamic stabilisation of new track types in the laboratory

In her doctoral thesis Sophie Feurig focuses on a detailed analysis of dynamic track stabilisation in the laboratory. An in-depth understanding of the system behaviour of the ballasted track sparks not just her enthusiasm.

How does a track maintenance machine think?

This question raises another question: “Is a track maintenance machine actually capable of thinking?” Yes, it is. Artificial Intelligence (AI) enables machines to learn from experience and adapt to new information and tasks. This requires machines to think autonomously. Artificial neural networks allow Plasser & Theurer machines to extract information and find generalised solutions.

Tracking ballast

Track ballast has many functions in the permanent way system. It is, amongst others, responsible for the load transfer into the subgrade, the drainage of the superstructure and the reliable position of the track panel. Even so, ballast is compared to other track components still a relatively unresearched area. With the use of the Discrete Element Method - a numerical calculation method for computing a large number of particles - and powerful computers it has now become possible to reliably determine the path of movement as well as the interaction of particles. Plasser & Theurer utilises this technology to gain new insights into the permanent way and so to optimise its track construction machines even further.
