TX Logistik AG

Updated: August 2026 – Anyone standing beside a freight corridor sees not only long trains but, regularly, single locomotives that seem to run through the area without a job to do. TX Logistik AG is one of the companies whose vehicles turn up like this – and a good opportunity to look at what such a light engine move actually is and how to properly identify a freight operator.

What is TX Logistik?

TX Logistik AG is a public limited company operating in rail freight transport, with its seat in Germany. The company name states the business area directly: “Logistik” stands for transport and freight, and the legal form AG is, in the rail sector, a sign of an operation of considerable size – small industrial railways practically never trade as a public limited company. At group level, the company belongs to the Italian state railway group Ferrovie dello Stato Italiane.

Companies of the same name are also registered in Austria and Switzerland. That’s a common pattern in cross-border freight transport: safety certificates, vehicle approvals and staff qualifications are regulated nationally, which is why cross-border services are often carried by several companies. In Germany, the Federal Railway Authority issues the certificates needed for this. Specific routes, customers and contracts change constantly and are therefore not listed on this page.

Light engine move: why a locomotive runs without wagons

It’s one of the most common questions at the lineside: a locomotive runs alone, headlights on, without a single wagon. That’s not a fault, but a light engine move, usually called “Lz” in operational terms. It’s its own train service with its own train number and has to be scheduled and planned just like a fully loaded block train.

A useful side effect: on a light engine move, the locomotive is fully visible, with no wagons blocking the view. For identification and documentation, those are the best conditions. For a broader look at making freight traffic more predictable, see the overview of freight train radar.

It’s worth distinguishing this from two similar sights. A double-header consists of two coupled locomotives jointly hauling a train – that’s not a light engine move. A dead-in-train locomotive runs unpowered within a train, usually to get it to its destination; it looks like traction but isn’t doing any work. Only a single machine running with no vehicles attached is a light engine move in the strict sense.

From the company’s point of view, such moves are a cost factor: they generate track access charges, energy consumption and staff deployment without moving a single tonne of freight. Train paths on the German network are allocated by DB InfraGO. That’s why dispatch tries to keep light engine moves as short as possible and schedules locomotives so they take on the next train straight after finishing one. So if you see a light engine move, that’s almost always a sign that a train service is starting or has just finished nearby – a useful clue if you’re looking for more traffic.

Typical vehicles and how to tell them apart

Which machine is actually hauling a given train depends on the diagram – and that changes daily. What stays stable is the pattern by which freight operators with international ambitions build up their traction fleet.

Type of duty	Typical vehicle type	Identifying feature
Heavy block train under wire	four-axle multi-system electric locomotive	several pantographs of different types on the roof
Cross-border service	approved multi-system machine	country markings and extra lettering on the vehicle
Trip/transfer work without wire	diesel locomotive	exhaust and radiator housings instead of pantographs
Light engine move (Lz)	single locomotive, no wagons	headlights on, high speed, no train formation
Double-heading on steep gradients	two locomotives in a row	two driving cabs one behind the other, one shared train

You can find specific vehicles in the class database – for example the widely used Siemens Vectron platform, the Bombardier TRAXX family, or the older multi-system machine Class 189. How to tell the Vectron variants apart in detail is explained in the article Identifying the Vectron.

Standing in the market

German rail freight is a competitive market: alongside the freight division of the state-owned group, DB Cargo, numerous private companies run their own services. Some specialise in container traffic, like METRANS Rail, others in heavy traction on mountainous terrain, like Lokomotion.

It’s especially dense on the classic north-south corridors. In the Middle Rhine Valley at Boppard, freight traffic between North Sea ports and southern Germany rolls past almost without a break. Further south, the Geislingen Incline shows what a machine can actually deliver and where banking is needed. And at the Brenner border station of Fortezza / Franzensfeste, you can see which vehicles a company uses for the Italian leg of its runs.

For you as an observer, that mainly means one thing: on any given main line, you’ll see trains of several companies within an hour. Anyone who just notes “freight train” is throwing away the most interesting piece of information. The systematic way to identify the operator is set out in the guide Who’s actually running it? Identifying the railway operator.

Making freight sightings worth analysing

Noting whether it was a light engine move is especially worthwhile. Such moves show how vehicles are shuffled between jobs – and over time build up a picture of which machines actually turn up regularly in a region.

Common mix-ups

• A single locomotive means a disruption – no, usually a scheduled light engine move.
• The logo means the operator – decals change, leased locomotives carry someone else’s colours. The data panel decides.
• Same name means same company – companies with the same name in several countries are legally separate.
• A multi-system locomotive means a foreign trip – such machines run just as often in purely domestic service.
• A container means combined transport – wagons with swap bodies and tank containers can look similar too.

Conclusion

TX Logistik stands for the part of German rail freight that isn’t painted red and still runs on a large scale. Anyone who wants to reliably identify such companies gets into two habits: reading the data panel, and not dismissing a single locomotive as a curiosity but recognising it for what it is – a scheduled light engine move within a diagram.
