Key takeaways

  • "Solutions" in the name points to a service: locomotive and crew are provided, the load belongs to someone else.
  • The locomotive doesn't reveal the client – at best the vehicle shows the operator, often only the lessor.
  • Light engine moves and assisting locomotives are especially common with traction service providers.
  • Workings are hard to predict, because they follow contracts rather than fixed routes.
  • Document the combination of locomotive, train formation and location – only together do they form a picture.

How to recognise this operator

Is this really Cargo Rail Solutions GmbH?

Tick off everything that applies to the train you are looking at right now.

  • Company lettering or sticker on a locomotive in someone else's livery
  • Data panel with country code and vehicle keeper marking of a lessor rather than the operator
  • Changing train formations – containers today, tank wagons tomorrow
  • Occasional light engine moves, i.e. locomotives without wagons on a positioning run
  • Assisting locomotive or double-heading with locomotives from different companies

Updated: August 2026 – A locomotive pulls a container train but carries neither the terminal operator’s colours nor the client’s. The next day, the same machine is coupled to tank wagons in a completely different corner of the country. Welcome to the business of traction services, for which the company name Cargo Rail Solutions stands as a prime example. This page explains how this model works and how to recognise such workings in the field.

What is Cargo Rail Solutions?

Cargo Rail Solutions GmbH is a railway operator in rail freight. The name combines the segment – “Cargo Rail” – with the word Solutions, which in the industry usually stands for a service: the company solves a transport problem for someone else instead of marketing its own freight.

This distinction explains why such companies are hard to pin down in the field. They turn up wherever there’s currently demand – and vanish again once the contract ends.

Three roles that rarely coincide

The keeper is shown on the data panel. The operator runs the train. The client ordered the service. With traction service providers, these are almost always three different parties – and you can only read off the first one from the vehicle.

When companies buy in third-party traction

The model looks exotic but makes plenty of business sense. There are five typical reasons, and each produces its own picture on the line.

Reason What’s behind it What you see
Peak demand more trains than own locomotives third-party locomotive in front of a familiar train
Breakdown locomotive faulty or out of service short-notice replacement traction
Missing licence section outside the company’s own authorisation locomotive change at a defined point
Staff shortage no drivers available third-party crew on the company’s own locomotive
New route traffic being built up, no own fleet yet changing vehicles over several weeks

For documentation that means: note the locomotive and the train formation. Only the combination later reveals whether it was likely a cover job or a regular working. The guide to identifying classes shows how to reliably identify vehicles along the way.

Light engine moves, assisting locomotives, double-heading

For observers, traction service providers are especially exciting for one reason: they produce the unusual train formations that are otherwise rare in everyday traffic.

What did you just see?

Two questions – then you'll know how to classify the observation.

Classification

Light engine move (Lz)

A positioning run. Vehicles are being brought to wherever they're needed next. Note down every single number – light engine moves are rare chances to log several vehicles at once.

Classification

Assisting locomotive or double-heading

Either extra tractive effort is needed, or a locomotive is simply being brought along. With vehicles from different companies, this is a clear sign of a service arrangement.

Classification

Regular train

The most common sight. Still worth checking the data panel: even an unremarkable train can be pulled by a hired-in locomotive.

Record rare combinations

Light engine moves and assisting-locomotive workings are fleeting – log them while you still have them in view.

Typical vehicles for flexible workings

Anyone selling traction needs vehicles that can be deployed almost anywhere. That’s why modern platform locomotives with broad licensing dominate – supplemented by used main-line locomotives for simpler tasks.

In the class database you’ll find typical examples: the platform Bombardier TRAXX, the standardisation-focused Siemens Smartron, and the dual-power locomotive Stadler EuroDual, which combines electric and diesel-electric operation in a single vehicle. Which of these a specific company uses changes with lease contracts – which is why no fleet list is given here deliberately.

Where you’ll realistically find workings like this

Cover and positioning runs concentrate wherever a lot of traffic converges. Good chances are offered by major hub stations, approach lines to marshalling yards, and the main freight corridors. On pure local passenger lines and branch lines without freight connections, the likelihood is low by contrast.

Another clue is times of high operational density: when a lot of traffic is running, the likelihood increases that a cover job or positioning run will be needed somewhere. Conversely, quiet weekend periods are usually unproductive for this kind of working.

Because such workings don’t follow a fixed pattern, community reports are especially valuable here. The article on the freight train radar in Germany describes how to use live information for this.

Safety is not negotiable

Storage sidings, shunting areas and operational land are cordoned off because unannounced movements happen there. Wagons are propelled, and locomotives move under radio remote control silently. Observe only from publicly accessible locations – that's enough for any good shot.

How to document a service working

For traction services, the usual note isn’t enough. Because the locomotive, the train and the client don’t line up, the sighting needs to carry more context than usual.

Is your sighting informative enough?

Tick off what you've recorded – from four ticks onward the working can be classified later.

  • Full vehicle number of every locomotive involved
  • Country code and vehicle keeper marking from the data panel
  • Company lettering or sticker, if present
  • Train formation: wagon type, approximate length, load
  • Location, direction of travel, date and time
  • Special features such as an assisting locomotive, dead-in-tow locomotive, or light engine move

An often overlooked point: also note what you couldn’t determine. “No company logo visible” is genuine information and stops a guess from later travelling into the collection disguised as an observation. This discipline matters more for service workings than elsewhere, because a great deal of guessing happens here – in forums just as much as in private lists.

Comparable companies nearby

To get a feel for the range, it helps to compare: Cargo Logistik Rail-Service also carries a service term in its name, boxXpress.de is clearly committed to containers through its name, and Havelländische Eisenbahn refers to a landscape rather than a product. Three naming logics, three completely different sets of expectations. Who’s actually running it? Identifying the railway operator describes how to systematically infer the company from that.

Common mix-ups

  • Locomotive equals train owner – with traction services, the locomotive and the load belong to different parties.
  • Light engine move equals operational disruption – positioning runs are scheduled, not an emergency.
  • Assisting locomotive equals heavy train – often the second locomotive is simply being brought along.
  • Sticker equals keeper – company logos on hired-in locomotives say nothing about the vehicle register.
  • Rare combination equals mistake – unusual train formations are everyday business in the service trade.

Verdict

Cargo Rail Solutions stands for a business model that makes freight traffic flexible while also making it look confusing. Anyone who cleanly separates the roles of keeper, operator and client quickly loses that confusion – and recognises unusual train formations for exactly what they are: the most interesting sights in everyday operations.

In short

When the locomotive and the train don't seem to match, a traction service is often behind it. Note both separately, and the sighting stays correct even if you never find out who the client was.

Summary

  • Traction service is a distinct product in rail freight, not just a stopgap.
  • The same locomotive can run for several clients within a few days.
  • Light engine moves, assisting locomotives and double-heading are important clues to service workings.
  • Contracts, fleets and lease arrangements change constantly – sightings therefore need a date.

Frequently asked questions

What does Cargo Rail Solutions do?

The company name points to a railway operator in freight traffic with a focus on services. "Cargo Rail" names the segment, "Solutions" the character of a solutions provider for others. Which services currently take priority depends on contracts and changes continually.

What is a traction service?

A company provides a locomotive and driver and hauls a train that another company has sold. This happens for cover duties, replacement services, staff shortages, or missing licences. For observers that means: the locomotive doesn't necessarily belong, operationally, to the train it's pulling.

What is a light engine move?

A run with one or more locomotives and no wagons – often referred to as "Lz". Such positioning runs happen when vehicles need to be brought to wherever they're needed next. Light engine moves are especially common with traction service providers, because their vehicles move between jobs.

What does an assisting locomotive mean?

A second locomotive is placed ahead of the actual train locomotive, either to get more tractive effort or simply to bring a locomotive along. When vehicles from different companies come together this way, it makes for an especially interesting sight – and a sign that several companies are involved.

How do I tell who a locomotive is running for?

Usually not from the vehicle at all. The data panel names the keeper, the lettering at best the operator. The client never appears anywhere. The context helps: fleet, load, direction of travel, and the question of which routes are even typical at this location.

Why are such companies' workings hard to predict?

Because they follow contracts. A replacement service can arise at short notice and a cover job can end again after two weeks. Unlike companies with fixed routes, there's no stable pattern – which makes every sighting a piece of documentary added value.

Which locomotives are used for traction services?

Preferably modern platform locomotives with broad licensing, because they can be deployed flexibly. Used main-line locomotives are added for tasks with no special requirements. Which machine actually runs is decided by availability on the day of the job.

Where's the best place to observe workings like this?

At major hub stations and along the main freight corridors, because positioning runs and cover jobs converge there. Stick to platforms, bridges and public paths; shunting areas, storage sidings and operational land are off-limits and cordoned off for good reason.
