Vossloh Rail Services Deutschland GmbH

Updated: August 2026 – Modern track has almost no joints left. What used to click rhythmically is today a continuously welded strand – and behind that lies a discipline all of its own. Vossloh Rail Services Deutschland GmbH carries this field right in its name: services to the rail. This page explains the core subject behind it.

What is Vossloh Rail Services Deutschland?

The company can be read straight off its name: Rail Services stands for services around the rail, and the suffix Deutschland for a national subsidiary within an internationally active corporate group – the Vossloh group. That sets it fundamentally apart from a freight or passenger railway: the product isn’t transport, but work on the track and on vehicles.

Exactly which services are offered is one of the details that changes – service ranges shift with contracts and market developments. What holds true permanently, on the other hand, is the technology behind it. And for rail services, that revolves above all around one question: how do you permanently join steel to steel?

Why welding happens in the track

In the past, rails were bolted together with fishplates, and a gap was left between the ends for thermal expansion. That very joint gap was the problem: it produces an impact on every passage, stresses vehicles and the track structure, wears quickly and is noisy.

Continuously welded track eliminates the joints. Thermal expansion isn’t ignored, but controlled differently – through tensioning the track in the ballast bed and through defined laying temperatures. The result: smoother running, less wear, longer service life.

The price for that is precision. A welded strand can no longer expand freely; the forces created by heating stay within the track. They’re carried by the interplay of sleepers, fastenings and ballast bed. That’s why the temperature at which a strand is welded and fixed isn’t a side issue – this condition determines how the track behaves later in heat and cold. For the same reason, work on welded track follows strict rules: whoever cuts the strand is intervening in a tensioned system.

This becomes visible in details most people never notice. Where continuously welded track meets a bridge or a section of different construction, transition structures are used that deliberately allow movement. Points, too, are special locations, because several strands come together there and the forces have to be guided differently.

The main methods at a glance

Method	Purpose	Typical situation	Distinguishing feature
Thermite welding	joining rails	individual joints, hard-to-reach spots	needs no large machinery
Flash-butt welding	joining rails	many joints in succession	requires a welding machine on site
Weld-repair	building up material	wear at the railhead or on points components	avoids replacing whole components
Grinding and dressing	finishing	after every weld	restores the rail profile
Testing the weld	quality assurance	after completion	carried out non-destructively on the finished track

The last row isn’t a formality: a weld is a highly stressed point in the track. That’s why testing is an inseparable part of the process.

Weld-repair: putting material back onto the rail

Wear doesn’t strike a rail evenly, but at individual spots: curves, points components, transitions. A complete replacement there would often be disproportionate – weld-repair instead builds up material at the specific point.

Long rails: logistics as a discipline in its own right

A very long rail can’t just be laid onto a wagon like a piece of steel. It spans several wagons at once, has to be allowed to flex through curves, and is pulled off in a controlled way at the worksite rather than unloaded. That requires purpose-built wagons, a matching train formation and practised procedures.

On top of that, transport and installation are closely linked in time. A long rail lying at the worksite blocks space and must be secured; one that arrives too late holds up the entire construction schedule. That’s why the order of wagons in the train isn’t a side issue, but part of the construction planning.

For observers, a long-rail train is unmistakable: a continuous load spanning many wagons, usually without load securing in the usual sense, but with guides and hold-downs instead. How to systematically identify unfamiliar vehicles and train profiles is shown in the guide to identifying classes.

Recognition in the field

Engineering workings don’t run to a timetable and are rarely announced. Typical traction is powerful diesel locomotives, such as modern examples like the Vossloh DE 18 and the Vossloh G 1000 BB, or classic shunting locomotives such as the Class 290. Which locomotive is actually hauling an engineering train on a given day changes daily – the type can still be reliably identified.

For comparison with other companies in the construction and logistics field, it’s worth looking at Schweerbau Logistik, Spitzke Logistik and H.F. Wiebe. How to separate the operating company from the keeper and the client is explained in the guide Who’s actually running it? Identifying the operator.

Common mix-ups

• Rail Services confused with a freight railway – the name describes a service to the rail, not transport.
• Every weld treated as the same – joining and building up are different tasks with different methods.
• Grinding equated with welding – grinding restores the profile, it adds no material.
• A long-rail train mistaken for an ordinary freight train – the continuous load across many wagons is the tell.
• National subsidiary confused with an independent group – the suffix “Deutschland” assigns it to a market, nothing more.

Conclusion

Behind the unassuming term “Rail Services” lies one of the most demanding techniques in railway operation. Without welding there would be no continuously welded track – and without long-rail logistics, the material would never reach the right spot. Knowing both, you’ll see a great deal more at the next worksite than just a barrier.
