Key takeaways
- Light locomotives are their own vehicle category – not simply small shunting locomotives, but a class with its own system and its own operating rules.
- The German light-locomotive system works with power groups and letters for engine type and power transmission.
- Manufacturer keys like ME 05 follow their own logic: letters for the type series and drive type, number for the size tier.
- The UIC type code 98 covers diesel shunting and light locomotives, as opposed to 92 for diesel main-line locomotives.
- Keeper, livery and location change constantly – only the builder's plate provides a stable identity.

Updated: August 2026 – Light locomotives are the least conspicuous traction vehicles of all: small, slow, mostly away from platforms – and often in service for decades. The Krauss-Maffei ME 05 belongs in this category. This page explains the German light-locomotive system, shows how manufacturer keys fit into it, and how you can reliably identify such vehicles in the field.
Spotted a light locomotive? Note it straight away.
Light locomotives often stand unnoticed for years – your dated sighting is often the only record.
What is the Krauss-Maffei ME 05?
The Krauss-Maffei ME 05 is a diesel light locomotive for shunting service from the Munich manufacturer’s type programme. It therefore belongs to the vehicle group that carries type code 98 in the European numbering system – diesel shunting and light locomotives, distinct from main-line machines with code 92. Krauss-Maffei’s rolling stock business passed to Siemens Mobility in the late 1990s – vehicles from the old industrial locomotive programme therefore carry the plate of a manufacturer that no longer exists in that form.
The name follows the manufacturer’s own logic, not the state-railway system: the letters place the vehicle in a type series and, as with many German locomotive builders, also indicate the power transmission at the same time, while the number denotes the size tier. For identification in the field that means: the name gives you a direction, the builder’s plate gives you certainty.
Understanding the German light-locomotive system
Anyone wanting to classify light locomotives should know the classic German system. It explains why designations like Köf or Kb look the way they do – and it provides the vocabulary that also describes manufacturer types.
| Component | Meaning | Example logic |
|---|---|---|
| K | light locomotive (Kleinlokomotive) | always comes first |
| second letter | engine type | ö for oil engine (diesel), b for petrol engine |
| third letter | power transmission | f for hydraulic transmission, e for electric |
| no third letter | mechanical power transmission | gearbox as in a commercial vehicle |
| power group | ranking by engine strength | roman numerals, ascending by power |
This system comes from the state-railway sector; it was not adopted by private works railways. Even so, it’s worth knowing: it describes exactly the features that also decide manufacturer types – engine type, power transmission and size class.
Assess the size
Light locomotives are noticeably lower and shorter than shunting locomotives. If the cab barely rises above the wagon buffers, you're in this category.
Count the axles
Two axles in a rigid frame are the norm for light locomotives. Three axles already point to a larger shunting locomotive.
Classify the drive
Coupling rods visible? Then the power runs via a jackshaft. No rods and one drive per axle point to electric transmission.
Comparable small vehicles can be found in the LKM V 10 C from East German locomotive building and the Gmeinder 190 hp / D 35 B. The hydraulic sister variant in the Krauss-Maffei programme is the MH 05. The general approach to identification is described in the guide identifying classes.
Light locomotives are collector's pieces
Because they're rarely photographed, every clean sighting with a works number is especially valuable.
Where light locomotives sit in railway operations
Light locomotives work wherever a large shunting locomotive would be oversized: at loading ramps, in workshops, on short private sidings. They rarely run far and usually only for a few minutes at a time – which makes them hard for observers to plan around.
You find light locomotives standing still, not running
Don't plan a sighting around a timetable. Instead, keep an eye out at motive power depots, heritage sites and works entrances – such vehicles often stand there clearly visible for hours.
Because many light locomotives have been preserved at heritage and society railways, event days are a realistic opportunity to photograph them up close and legally. What to note down while doing so is described in the guide to a sighting log.
The typical tasks such vehicles take on can be summed up well: positioning single wagons at a loading ramp, repositioning parked vehicles within a site, serving workshop tracks and occasionally running a short transfer to a private siding. None of that needs a big machine, just an agile vehicle with a good all-round view and a short wheelbase.
That also explains why light locomotives are so inconspicuous out in the field: they rarely work where passengers go, and their duties last minutes rather than hours. Anyone wanting to see one either has to be at the right place at the right time by chance – or seek out locations where such vehicles are permanently parked and remain visible from publicly accessible paths.
Safety around shunting areas
Small locomotive, same danger
Even a light locomotive moves wagons with dozens of tonnes of mass – and it does so unannounced, without a signal and often pushed. Parked vehicles can start rolling at any time. Works, port and private siding railways are private property; entering them is not permitted even without a fence. The basic rules are summarised in the article on safe distance from the track.
Why light locomotives survive so long
Light locomotives are among the longest-lived rail vehicles of all. There are solid reasons for that, and they also explain why you still encounter such vehicles today.
- Simple construction. Little electronics, robust mechanics, a manageable number of parts – much of it can be repaired in an ordinary workshop.
- Low mileage. A vehicle that covers a few hundred metres a day wears out slowly. Operating hours pile up, kilometres hardly do.
- No need for replacement. As long as the task stays the same – repositioning wagons, serving a ramp – there’s no operational reason for new procurement.
- Cheap to acquire. Retired light locomotives are affordable for societies and small businesses, giving them a second and third life.
For documentation, an important point follows from this: a vehicle can stand in the same place for decades and still be recorded nowhere. Anyone who discovers a light locomotive on a private siding or in a workshop corner has a good chance of owning the only dated photo of it.
Stationary vehicles count too
For this vehicle group, the parked state is the norm, not the exception. Note such finds just as carefully as a moving train – with date, location, works number and visible condition.
Common mix-ups
It suggests a light locomotive if …
- the vehicle is noticeably smaller than a freight wagon next to it
- two axles run in a rigid frame
- the cab is designed for one or two people
- the builder's plate shows a manufacturer's type name rather than a class number
Look more closely if …
- the vehicle has three axles but looks very compact
- a rebuild with a new cab has taken place
- only a painted-on operating number without a manufacturer's information is visible
It's not a light locomotive if …
- the vehicle has two full driving cabs and main-line equipment
- it runs on two bogies
- the vehicle number begins with 92 – that marks a diesel main-line locomotive
Conclusion
The Krauss-Maffei ME 05 is a typical representative of a vehicle class about which there’s hardly any public data – but which can be classified very well with some systemic knowledge. Size, axle count and drive type lead to the category, the light-locomotive system provides the vocabulary, and the builder’s plate the identity. That’s all it takes for a clean sighting.
In short
Light locomotive rather than shunting locomotive: compact frame, two axles, close-range use. Classify by size, axle count and drive type, and secure the identity via the builder's plate.
Keep a record of your light-locomotive finds
Type, works number, location and date in one place – that pays off especially for rarely documented vehicles.
Summary
- Light locomotives form the lowest tier of traction vehicles: small, agile, built for short-range work, and kept in service for decades.
- The classic German light-locomotive system explains why designations like Köf or Kb look the way they do.
- Manufacturer types like the ME 05 can be read with the same logic: letters for the technology, number for the size.
- Observe only from publicly accessible locations – works railways and private sidings are private property.
Frequently asked questions
What is a light locomotive?
A light locomotive is a lightweight traction vehicle for close-range shunting work. It is smaller and less powerful than a shunting locomotive and was classed in Germany as its own vehicle category, among other things with simplified requirements for operating staff. Typical tasks are repositioning individual wagons and serving loading points.
How is the German light-locomotive system structured?
The classic designation begins with K for Kleinlokomotive (light locomotive). The second letter marks the engine type – ö for oil engine, i.e. diesel, b for petrol engine. A third letter stands for the power transmission, for instance f for hydraulic transmission or e for electric transmission. If it's missing, the transmission is mechanical. In addition, there are power groups that rank the vehicles by engine strength.
What does the designation ME 05 mean?
It comes from Krauss-Maffei's type programme, not from the state-railway system. The letters place the vehicle in a manufacturer's type series and, as with many German locomotive builders, also indicate the power transmission at the same time; the number denotes the size or power tier. In the end, the information on the builder's plate is what's binding.
What's the difference between a light locomotive and a shunting locomotive?
The difference lies in mass, power and purpose. A shunting locomotive moves whole wagon groups and is driven by trained locomotive drivers. A light locomotive is meant for single wagons and short distances. In the European numbering system, both are grouped under type code 98.
Why do light locomotives carry the type code 98?
The twelve-digit European vehicle number begins with a type code for traction vehicles. 98 stands for diesel shunting and light locomotives, 92 for diesel main-line locomotives. The classification depends on purpose and registration, not on build year or design.
Where can you still see light locomotives today?
On works railways, private sidings, in motive power depots and very often at heritage and society railways. Light locomotives are often used for particularly long periods because they are simply built and cheap to maintain. Locations and keepers change constantly, though – check the current status before planning a trip.
How do I recognise the power transmission from the outside?
Coupling rods between the axles indicate mechanical or hydraulic transmission with a jackshaft. If they're absent and each axle has its own drive, that points to electric transmission. A reliable classification only comes with the builder's plate or a photo of the drivetrain.
Am I allowed to photograph light locomotives on works premises?
Works, port and private siding railways are private property. Photography there is only permitted with the operator's permission, and entering track areas is out of the question. From a public path the situation is different, but it depends on the individual case – ask beforehand if in doubt.
