Key takeaways
- The Eurolight is a genuine main-line locomotive: cabs at both ends, carbody design, built for passenger and freight trains.
- Diesel-electric: generator and traction motors instead of a hydraulic transmission – unlike the Kiel G types.
- Best known as the British Class 68, developed and built in Valencia, Spain.
- Don't confuse it with shunting locomotives: there is no centre cab and there are no end hoods at all.
- Deployment, keeper and livery change – always check the current situation.

Updated: August 2026 – Among the vehicles with a Vossloh label, the Eurolight stands out. It has no centre cab and no end hoods, and it was not built in Kiel but in Valencia. It became known as the British Class 68. This page places the platform, shows its identifying features and explains why it differs so clearly from the other Vossloh diesel locomotives.

What is the Vossloh Eurolight?
The Vossloh Eurolight is a four-axle diesel-electric main-line locomotive, developed and built at Vossloh España in Valencia, Spain. The site later passed to Stadler Rail, which is why the same platform appears under different company names depending on when it was built. Its best-known version is the British Class 68.
It is conceived as a multi-purpose locomotive for mixed traffic: passenger trains and freight trains with the same machine. That requires a higher top speed than pure freight diesel locomotives and at the same time enough tractive effort for heavy loads – a design target that many types do not aim for in this way. The Bo’Bo’ wheel arrangement with four individually driven axles is the fitting technical framework for it.
The silhouette makes the difference
Within the Vossloh world, the Eurolight is visually the clear exception, and that is exactly what makes identification easy.
Count the cabs
Two cabs, one at each end. The Kiel shunting and trip locomotives have a single cab in the middle instead.
Check the body
A continuous enclosed carbody without separate end hoods. The cooling system and exhaust ducting are integrated into the roof section.
Look at the running gear
Four axles in two bogies, each axle individually driven by a traction motor – the typical Bo'Bo' arrangement of diesel-electric main-line locomotives.
Read the number
The twelve-digit vehicle number begins with 92 for a diesel locomotive. In the British version, the Class 68 running number appears as well.
If you want to internalise the order of these checks in general, you will find it in the guide to identifying classes. The structure of the twelve-digit number is explained in the article on the UIC number.
Placing it: an all-rounder rather than a specialist
| Criterion | Vossloh Eurolight | Kiel G/DE types |
|---|---|---|
| Design | Carbody, two cabs | Centre cab, two end hoods |
| Power transmission | diesel-electric | hydraulic (G) or diesel-electric (DE) |
| Main task | Passenger and freight trains on main-line duties | Shunting, trip workings, light line duties |
| Main market | Great Britain (Class 68) | Germany and neighbouring countries |
| Chance of a sighting in Germany | very low | high |
The table makes it clear why the two concepts do not get in each other’s way: they solve different tasks. A German counterpart with a similar aim – a main-line diesel locomotive for mixed traffic – is the Siemens ER 20. Within the Vossloh world, the diesel-electric Vossloh DE 18 is technically the closest relative, albeit with a completely different design.

Why a Spanish locomotive carries a Vossloh label
A regular source of confusion is the question of why a locomotive built in Valencia runs under the same brand name as the Kiel shunting locomotives. The reason is corporate history, not technology.
In the late 1990s, Vossloh took over locomotive building in Kiel, with its MaK tradition, and later built up a second pillar in Spain. Both sites developed independent product lines – Kiel the shunting and trip locomotives with a centre cab, Valencia the main-line locomotives with a carbody. Later the sites went separate ways: Valencia to Stadler, Kiel into other hands.
For spotters this means: the brand name says little about the design. If you want to identify a locomotive from Vossloh, you first have to establish which product line it comes from. The silhouette usually answers that immediately – a centre cab means Kiel, a carbody with two cabs means Valencia.
Memory aid for the first glance
Two cabs plus a carbody equals a main-line locomotive. One cab in the middle plus two end hoods equals a shunting and trip locomotive. This distinction works across all manufacturers and is the quickest way into any identification.
Main-line or shunting locomotive – the most important basic distinction
The Eurolight is ideal for practising a distinction that applies first with every diesel locomotive: is this a main-line locomotive or a shunting and trip locomotive?
A main-line locomotive is designed for running. It has cabs at both ends so that it can run in either direction without running round, an enclosed body for aerodynamics and weather protection, and a top speed that suits line services. The UIC type code is 92.
A shunting or trip locomotive is designed for work at a standstill and at walking pace. It has a cab in the middle so that the view of both ends of the vehicle and of the shunting staff remains clear, plus walkways, handrails and steps. Pure shunting and small locomotives carry the type code 98.
In between lies a large grey area where most Kiel types sit: shaped like a shunting locomotive, approved like a main-line locomotive, type code 92. The Vossloh G 2000 BB is a good example – it looks like a large shunting machine and still hauls main-line freight trains.
The Eurolight, by contrast, clearly belongs in the first camp. If you make this assignment first, you have already halved the field of possible types before checking the first detail. That is exactly why it comes right at the start of every good identification routine.
Spotting and archiving
Because the Eurolight is not an everyday vehicle in Germany, the spotting task shifts: it is less about the good location and more about the right information at the right time. Delivery runs, trade fair appearances and special workings are the realistic opportunities, and they are usually announced only at short notice.
That makes it all the more important that the few pictures you get remain easy to find later. A cleanly structured archive with date, location, vehicle number and type is worth more for rare vehicles than for any everyday subject – how to build one is described in the guide to the photo archive for spotters.
Safety and changing information
Track areas, operational railway land, stabling sidings and depots are off-limits or private property – even for a rare visiting vehicle. Take photos from publicly accessible locations. The keeper, livery and area of operation of such locomotives also change regularly; treat any older information as a snapshot.
Common mix-ups
It points to the Eurolight if …
- the locomotive has cabs at both ends
- the body is an enclosed box without end hoods
- four axles run in two bogies
- British Class 68 numbers are marked on it
Take a closer look if …
- you are looking at another modern four-axle main-line diesel locomotive
- the locomotive is in a neutral livery with no reference to the manufacturer
- you only see it from a long way off or at an angle from behind
It is not a Eurolight if …
- the locomotive has a centre cab between two end hoods
- you count six axles
- the vehicle number begins with 91 – then it is an electric locomotive
Verdict
The Vossloh Eurolight shows how little a brand name reveals about a design. It shares only the label with the Kiel shunting locomotives, nothing else: different design, different task, different market, different site. If you start identification with the silhouette rather than the logo, you will get there in a few seconds with this one.
In short
Carbody, two cabs, four individually driven axles, diesel-electric: that is the Eurolight. A rare visitor in Germany, at home in Great Britain as the Class 68 – and visually impossible to confuse with any Kiel locomotive.
Summary
- The Eurolight was created at Vossloh España in Valencia, a site that later passed to Stadler.
- It is designed as a multi-purpose main-line locomotive and covers both passenger and freight duties.
- In Germany it is a rare visitor; its home is the British market with the Class 68.
- Its design with cabs at both ends sets it clearly apart from the Kiel shunting and trip locomotives.
Frequently asked questions
What is the Vossloh Eurolight?
A four-axle diesel-electric main-line locomotive, developed and built at Vossloh España in Valencia. It is designed as a multi-purpose locomotive for passenger and freight trains and became known above all as the British Class 68. The Valencia site belongs to Stadler today.
How do I recognise the Eurolight?
By its design: cabs at both ends, an enclosed carbody without end hoods and four individually driven axles in two bogies. That makes it fundamentally different from the Kiel shunting and trip locomotives with their centre cab.
What does the Eurolight have to do with the Class 68?
The Class 68 is the British version of the Eurolight platform, adapted to the loading gauge there and to British approval requirements. If you know the Class 68, you know the Eurolight – the platform and basic concept are the same.
Is the Eurolight diesel-hydraulic or diesel-electric?
Diesel-electric. The diesel engine drives a generator whose current feeds the traction motors. That clearly distinguishes it from the hydraulic G types from Kiel, where a hydrodynamic transmission transfers the power.
Can you see the Eurolight in Germany?
Only as an exception. Its main market is Great Britain. In Germany it is not an everyday vehicle – if you are looking for one here, you are reliant on special cases, delivery runs or trade fair appearances. So check current sighting reports rather than hoping for regular service.
Why does it carry the UIC type code 92?
Because it is a diesel locomotive fit for main-line service. The first two digits of the twelve-digit vehicle number form the UIC type code: 92 for diesel locomotives, 91 for electric locomotives, 93 for high-speed multiple units, 98 for diesel shunting and small locomotives.
What is a multi-purpose locomotive like this built for?
For networks with mixed traffic, where the same machine is expected to haul a passenger train in the morning and a freight train in the afternoon. That requires a higher top speed than pure freight locomotives and sufficient tractive effort at the same time – a compromise not every design makes.
How do I tell it apart from a Kiel G or DE locomotive?
By the basic shape. The Kiel types have a centre cab between two end hoods and are tailored to shunting and trip duties. The Eurolight has a continuous carbody with cabs at both ends. These two silhouettes are hard to confuse.
