Innovations for cost-effective track maintenance

For over seventy years, Plasser & Theurer has been dedicated to developing and building track maintenance machines with the aim of maximizing benefits for railway infrastructure companies and construction companies. In that sense, the focus lies on higher working speeds, improved work quality, better environmental friendliness, optimized ergonomics, and maximum safety for staff. Our continuously expanding portfolio of products and services offers customized, cost-effective solutions for the construction, maintenance, and monitoring of precise and sustainable rail infrastructure.

On track to autonomous track maintenance

With track possessions becoming shorter and a shortage of qualified staff, infrastructure managers and contractors face major challenges. The pressure on railways to increase capacity and handle more trains using the existing infrastructure is increasing. This means delivering greater high-quality output in shorter track possessions.

Coordinated maintenance tasks for maximum availability

Our end-to-end approach is based on a simple premise: The right measures are implemented at the right time in the best place with the appropriate technology.

Plasser CompactFlex 2x4

Efficient maintenance for Busan’s metro

Humetro operates four metro lines in the South Korean metropolis of Busan, and with the Plasser CompactFlex 2x4 it has a powerful tool for maintaining the approx. 167 km long network.

Increased efficiency

A small "e" with a major impact!

When it comes to tamping machines, Plasser & Theurer used all-electric drives on innovative carriers of technology very early on. Today, companies that gradually convert their fleets to electric drive technology also benefit from this, for example, when combining modern internal combustion engines with electric work units.

Sustainable modernization

Unimat 08-275 retrofit

Plasser & Theurer retrofits are winning over more and more customers. In 2023, the Estonian track maintenance company GoTrack also decided to have a Unimat 08-275 built in 1985 completely refurbished and modernized. At iaf 2025 in Münster, the machine will be part of our outdoor exhibit.

Tension force redefined

Plasser CatenaryLiner 300 with innovative friction winch

The Plasser CatenaryLiner 300 is the latest addition to our family of catenary installation and maintenance machines. Based on the proven FUM series, the Plasser CatenaryLiner 300 impresses with a patented innovation: the line laying system with a newly developed shoe-chain drive on the friction winches.

The new Plasser UnimatSimulator

Customized training for operating your universal tamping machine

The use of modern simulation tools for training maintenance machine operators and perfecting their skills is becoming increasingly popular. It is reason enough for Plasser & Theurer to offer even more in this area with the new UnimatSimulator. Training for operating eight different universal tamping machines is currently available on the simulator, meaning that it can be highly customized to each user and machine configuration.

Sustainable services for your machine fleet

In modern track maintenance, the reliability of railway track depends to a large extent on the maintenance machines used. Are they available? Are they working with the expected efficiency? Do they deliver the required quality? Plasser & Theurer machines fulfil the highest standards in all areas.

Analytics-as-a-Service

Strength in unity for better decisions

In an economic sector with high maintenance costs, it is essential to operate and maintain track maintenance machines efficiently. Gaps that occur in the flow of information after leaving the machine depot and going back must be closed.

Recovering valuable ballast

The advantages of high-quality ballast cleaning have a particularly positive impact on the heavy-haul railways of Queensland, in the north-eastern part of Australia. On the one hand, transporting coal entails very heavy loads; it also introduces higher levels of fines into the track area. On the other hand, new ballast is expensive and transport routes are long. Reusing ballast, a cost-intensive resource, is therefore not only sustainable, but also a significant economic factor.

P-IC 3.0: more power, more security, more options

P-IC and tmOS combine to create a future-oriented control solution that drives efficiency, flexibility, and the path to fully automated machines.

Plasser ScreenLiner

Ballast cleaning at the right time saves money in the long term and increases availability

Railway ballast has many important functions to fulfil in the rail-sleeper-ballast bed system. An increase in the amount of fines as a result of foreign matter, or induced through wear, hampers its functionality.

Disruptive approaches for an innovative worksite warning system

PRODES is based in Vienna and is dedicated to creating the highest possible benefit of railway safety, in accordance with their Latin company name meaning "to use", i.e. "you use”. Their aim is to maximize the safety of the railway system in all its operational processes, in particular, to protect employees at the worksite from approaching trains and around the track maintenance machine itself in the best possible way.

ETCS: one system for Europe's tracks

The railway infrastructure in Europe is changing fundamentally: with the mandatory introduction of the ETCS (European Train Control System), the continent is paving the way for standardized, interoperable rail transport. This poses new challenges for both infrastructure companies and vehicle manufacturers.

Rail Management as a Service

The rail life cycle – an end-to-end analysis

The railway system is characterized by the fact that the two components, vehicle and track, touch at a central point (which is actually a surface): at the wheel-rail contact. It is where the entire interaction (transmission of forces) between the vehicle and the track takes place. To understand how rails achieve their maximum service life, it is worth analysing the rail life cycle.

Plasser ATMO

Innovation with success: from prototype to market-ready service

Since the prototype was first set up in May 2020, the Plasser ATMO grinding trailer has set important milestones in rail maintenance in urban areas. Developed as part of the Shift2Rail initiative and designed for the special requirements of tram systems, it combines oscillating and sliding grinding to create a perfect rail surface.

Innovative maintenance with the Plasser MultiCrafter 12.5 E³ C/I

In order to ensure the reliable operation of the two suburban railway lines in the Zurich Transport Network (ZVV), Sihltal Zurich Uetliberg Railways (SZU) has purchased a Plasser MultiCrafter 12.5 E³ C/I for efficient ancillary work along the railway line. With the hybrid-powered track motor vehicle, the Swiss transport company is paving the way for an even more sustainable maintenance strategy.

Infrastructure data and asset capture in the digital age

Increasing capacity on existing infrastructure requires modern tools in asset management. The high capacity of a track is directly linked to sound knowledge of assets and maintenance tailored to that end. The prerequisites for this are combined measuring data capture and professional diagnostics.

Global reach with local excellence

Plasser & Theurer is a globally active company with a global network of partner companies. This international approach allows us to be close to customers on the one hand and, on the other hand, enables high production in the global manufacturing network. The production facility in Karjan, India is particularly noteworthy.

200 years of the railway – pioneers, steam locomotives, and the first line

Something incredible happened in the north of England 200 years ago: a steam locomotive hauling several wagons travelled from Stockton to Darlington. And this train not only transported coal and other goods, but also people.

Modern diagnostic technologies for reliable railway infrastructure

With the coronavirus pandemic painfully impacting railway operating companies, the number of passengers transported by rail has risen continuously over the last twenty years without the infrastructure having grown to the same extent. This leads to significantly higher train frequencies, higher tonnages, and shorter service breaks at night. Higher wear versus shorter maintenance windows – continuous, uninterrupted infrastructure diagnostics can de-escalate this conflict.
