Event-based cameras as the key to precise sleeper detection

Sleepers hidden under the ballast are a particular challenge when tamping. Event-based cameras could make machine operators’ work easier, protect sleepers from damage, and pave the way for fully automating the tamping process.

Smart technologies

Step by step to an automated tamping process

Increasing capacity utilization, shorter track possessions, and staff shortages require maintenance measures to be optimized. The automation of work processes is therefore becoming increasingly important. An essential basis for this is to divide complex processes into individual steps in order to identify key factors with an impact. This method has already proved itself in tamping.

Machine data treasure hunt

The aim of predictive maintenance strategies is to estimate the optimum time for maintenance measures. With special machine construction, characterized by small production quantities, conventional statistical or AI-supported data analyses quickly reach their limits. What is needed is a concept that derives specific recommendations for action from the wealth of machine data.

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.

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?

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.

Smart technologies

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.

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.

It started with the vision of an autonomous tamping machine

The turnout tamping assistance system “PlasserSmartTamping – The Assistant” by Plasser & Theurer helps the operator to manage the operational systems of the machine and represents a major step towards the automation of tamping machines.

Digital Twin – The new world of track construction

In the age of 4.0, the digital transformation poses great challenges to the railway: both the users’ need for mobility and the operators’ opportunities to manage the track have changed. The digital revolution changes the order of things, requiring us to rethink and change the way we work.

The Shift2Rail Joint Undertaking

As the world’s resources become scarcer and climate change poses an ever-increasing threat, the future of Europe lies in embracing sustainable development strategies and investing in sustainable solutions to meet its long-term challenges.
