End-to-end process pre­sented in Sweden

Als Entwickler erfüllt es uns mit Freude und einem gewissen Stolz, wenn unsere neuesten Technologien begeisterte Reaktionen hervorrufen. Das war auch im Herbst 2022 der Fall, als unser Versuchsträger, ein vollelektrischer Unimat 09-4x4/4S E³, im Rahmen von Shift2Rail seine Fähigkeiten unter Feldbedingungen in Schweden demonstrieren konnte.

Complete turnout ins­pec­tion in four minutes

A new non-contacting measuring system makes it possible! The system records all the necessary parameters during a short pass over the main track and the diverging one. Another great benefit: it provides detailed image data. This data can be used to assess the condition of key components such as the common crossing, blades, or important system parts such as fastenings, drive units, and cable ducts.

Research on syn­thetic fuels in track main­te­nance

We have set ourselves the goal of advancing carbon-neutral track maintenance and thus contributing to even greater rail sustainability. In addition to our own E³ hybrid machines, synthetic fuels in particular are an important alternative. Therefore, newly manufactured machines can already be delivered so they are compatible for synthetic fuels.

Re­vo­lu­tio­nary track ins­pec­tion from the air

Unmanned Aircraft Systems (UAS), auch bekannt als Drohnen, sind zu einem unverzichtbaren Werkzeug für eine Vielzahl von Branchen geworden. Durch ihre Fähigkeit, über große Entfernungen hinweg hochpräzise Daten und detaillierte Bilder zu sammeln, revolutionieren UAS Inspektion, Inventarisierung und Digitalisierung von Eisenbahninfrastruktur. Im Hintergrund verarbeitet intelligente Software die enormen Datenmengen und liefert handfeste Entscheidungsgrundlagen.

The tamping unit that un­ders­tands the ballast

Just like the sense of touch enables humans to handle objects according to their texture, “sensing” tamping tines enable the machine to treat ballast in an optimum manner. But how do you teach a tamping machine a sense of touch?

The highly ver­sa­tile machine for pre­dic­tive main­te­nance

For the sake of economic efficiency, track construction and maintenance increasingly rely on a holistic approach that takes all relevant factors and parameters into account. The basis for this is high-resolution data of the individual track components.

Pre­dic­ti­ve­Tra­ck­View

We are currently developing PredictiveTrackView, a comprehensive tool for track infrastructure operators. Its goal is to exhaust all possibilities Building Information Modeling (BIM) offers to make planning and performing sustainable maintenance measures and asset management as efficient and easy as possible - all thanks to the digital twin in the virtual space.

Mul­ti­channel GPR tech­no­logy detects munition remnants and other obs­tacles

Foreign objects in the ballast bed and track substructure, such as munition remnants, can significantly restrict or delay maintenance work. Metal detectors, magnetometers, and conventional GPR systems cannot reliably detect objects in the track bed. Thanks to our multichannel GPR technology with increased scanning density, a tomographic analysis of the track is possible and, by extension, localisation is much better.

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.

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.

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 sta­bi­li­za­tion of new track types in the la­bo­ra­tory

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.
