Key takeaways
- MH 05 is a manufacturer's type designation from Krauss-Maffei, not a state-railway class number.
- The letters mark the type series and drive type, the number the size tier within the programme – only the builder's plate is binding.
- Radio remote control is widespread on shunting locomotives: it allows single-person operation, because one person both steers and watches the shunting path at the same time.
- The UIC type code 98 marks diesel shunting and light locomotives, as opposed to 92 for diesel main-line locomotives.
- Keeper, livery and location change constantly – note every detail with a date.

Updated: August 2026 – A small shunting locomotive starts moving, no one sits in the cab, and next to it walks a person with a box in front of their stomach: that’s exactly what modern shunting operation looks like. The Krauss-Maffei MH 05 stands for the vehicle size where this happens particularly often. This page explains the type name, radio remote control and its consequences for observation and safety.

What is the Krauss-Maffei MH 05?
The Krauss-Maffei MH 05 is a small diesel shunting locomotive, or light locomotive, from the Munich manufacturer’s type programme. It belongs to the vehicle group with UIC type code 98 – diesel shunting and light locomotives – clearly 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 type name follows the manufacturer’s own logic: the letters place the vehicle in a type series and, as with many German locomotive builders, also indicate the type of power transmission at the same time, while the number stands for the size tier within the programme. The electrically transmitting sister variant carries the designation ME 05 – the difference lies in the drivetrain, not in the vehicle’s size.
Radio remote control: what has changed in shunting work
Classic shunting operation needed at least two people: one in the cab, one at the train giving signals. With radio remote control, both roles merge. The person in control walks alongside the wagon group, sees the shunting path directly and operates the locomotive via a portable device.
Control unit instead of a driving cab
Power notch, direction of travel and brake all run through an operating device that's slung over the shoulder or worn in a harness. The cab often stays empty as a result.
Line of sight instead of signalling
Because the person in control stands directly at the shunting path, shouted instructions and hand signals over longer distances become unnecessary. That reduces misunderstandings.
Visible retrofits on the vehicle
Radio aerials on the roof, additional flashing lights and warning markings are the typical outward traces of remote-control equipment.
| Feature | Classic shunting operation | Radio remote-controlled operation |
|---|---|---|
| Cab occupied | permanently | often empty |
| Signalling | hand signals or radio between two people | largely unnecessary |
| Visible equipment | nothing unusual | roof aerials, extra lights, markings |
| Recognisability for outsiders | movement is announced by staff | movement looks self-triggered |
| Photographic consequence | crew visible in the cab | person with control unit next to the vehicle |
An empty cab doesn't mean it's standing still
A remote-controlled locomotive can start moving at any time without anyone sitting in the driving cab. In shunting areas, vehicles are moved unannounced, pushed and without a signal anyway; parked wagons can start rolling. Entering track areas is out of the question, and works and private siding railways are private property. The basic rules are set out in the article on safe distance from the track.
Document remote-controlled locomotives
Aerials, extra lights, markings – note such details too, they indirectly help date a sighting.
Identification in the field: the short checklist
Do you have enough for a solid sighting?
- I identified the axle count and frame type.
- I know whether coupling rods are present.
- I read or photographed the builder's plate.
- I noted the date and location.
- I recorded whether radio aerials are present.
Comparable small shunting vehicles can be found in the Henschel DH 240 B and the Gmeinder 250 hp. How to pass on observations of this kind in a structured way is described in the guide to reporting a sighting.
Where and how to observe such locomotives
Small shunting locomotives work at close range: loading points, works entrances, transfer sidings. They run briefly, often change direction, and stand for long stretches in between. For observers that means: patience beats a timetable.
A vantage point with a clear view of a transfer siding from a public road or bridge is usually the best solution. The guide to marshalling yard spotting describes how to find such locations and what’s allowed there. For comparison, it’s also worth looking at similar types like the O&K MV 6 a. Once you’ve observed when loading and handovers happen, you can plan your next visit far more precisely – recognising patterns is more valuable for this vehicle group than any timetable research, because there simply is no timetable.
Shunting radio: what you hear when you can’t see anything
Alongside remote control, there’s a second radio application in shunting work: shunting radio for communication between the people involved. The two are technically different but leave similar traces on the vehicle – aerials, mounts, extra equipment in the cab.
For observers, one thing is especially relevant: communication doesn’t replace visibility. Even when work is coordinated, a shunting movement remains unpredictable for outsiders. You don’t know which move has just been agreed, and as a rule you won’t hear it either.
- Pushed movements are the norm. The locomotive pushes wagons, the driving position is at the rear end, and no one walks ahead giving a warning.
- Parked wagons aren’t reliably stationary. They can be drawn into a shunting movement without any advance sign.
- Starting off happens with no lead time. For a light locomotive, only a few seconds separate standstill from movement.
From this follows the approach that works well for this vehicle group: observe from a safe distance, work with focal length rather than proximity, and choose a vantage point that lets you overlook the scene rather than standing in the middle of it. Everything you need for a complete sighting – axle count, body shape, builder’s plate, markings – is available from a public path.
Common mix-ups
It suggests a small works locomotive if …
- the vehicle is noticeably smaller than the wagons it moves
- two axles run in a rigid frame
- shunting steps and an all-round handrail are present
- the builder's plate shows a manufacturer's type name
Look more closely if …
- the locomotive carries aerials and extra lights that look retrofitted
- a new cab sits on an old frame
- no manufacturer's details are visible, only an operating number
It's not a light locomotive if …
- the vehicle runs on two bogies
- it has two full driving positions and main-line equipment
- the vehicle number begins with 92 – then a main-line diesel locomotive is present
Conclusion
The Krauss-Maffei MH 05 is a vehicle you rarely see and even more rarely find documented. It can still be identified: by size, axle count, drive type and builder’s plate. And anyone observing in shunting areas should keep the most important consequence of radio remote control in mind – that an empty cab says nothing about whether a locomotive is moving.
Anyone regularly out and about near works and private siding railways develops a feel over time for what movements are coming: when staff turn up with a control unit, when points are switched, or when an engine revs up at idle. That instinct doesn’t replace a safe distance, though. It only helps you catch the right moment for a photo – from a public vantage point, with plenty of distance from the track.
In short
Small shunting locomotive with a manufacturer's type plate, type code 98, often remote-controllable. Identify via axle count and builder's plate – and never assume an unmanned vehicle is standing still.
Collect light locomotives systematically
Type, works number, location and date in one app – that's how an overview emerges that barely exists publicly.
Summary
- Small shunting locomotives like the MH 05 move single wagons and wagon groups at close range around works and private siding railways.
- Remote-control operation has substantially changed shunting work and leaves visible traces on the vehicles.
- For observers that means: an empty cab doesn't mean the locomotive is standing still.
- Works and private siding railways are private property; observe only from publicly accessible locations.
Frequently asked questions
What does the designation Krauss-Maffei MH 05 mean?
It comes from the Munich manufacturer's type programme. The letters in front place the vehicle in a 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. The binding information is on the builder's plate of the individual machine.
What is radio remote control in shunting work?
In remote-controlled shunting movements, one person operates the locomotive via a portable control unit while walking alongside or ahead of the wagon group. Driving, braking and reversing all run over radio. The advantage: the person in control sees the shunting path directly and doesn't have to rely on shouted instructions.
How do I recognise a remote-controlled shunting locomotive?
By radio aerials on the cab roof, by additional warning lights or flashing lights, and often by conspicuous stickers or markings referring to remote-control operation. The surest sign is a moving locomotive with an empty cab and a person with a control unit walking beside it.
Is a remote-controlled locomotive more dangerous for bystanders?
Shunting areas are inherently dangerous, regardless of the control method. What's important to know is: a locomotive can start moving without anyone sitting in the cab. Anyone who assumes an empty vehicle is standing still is mistaken. Always keep your distance and don't enter track areas.
Why do shunting locomotives carry the type code 98?
The twelve-digit European vehicle number begins with a type code for traction vehicles. 98 marks diesel shunting and light locomotives, 92 diesel main-line locomotives. What matters is the vehicle's purpose and registration, not its size or age.
Where do you encounter a Krauss-Maffei MH 05?
Most likely on works railways, private sidings and loading points, as well as at heritage and society railways. Such locations are almost always private property. Keeper and location also change regularly, because used light locomotives are traded and leased – check the current status before setting off.
What's the difference between hydraulic and electric power transmission?
With hydraulic transmission, a torque converter passes the engine's power on mechanically, often via a jackshaft and coupling rods. With electric transmission, a generator feeds traction motors on the axles. From the outside, the difference is mainly visible from the presence or absence of coupling rods.
How do I sensibly document such a locomotive?
Note works number, type, date, location and livery – in that order. Add a side-on photo for axle count and design, plus a detail shot of the builder's plate. Because keeper and livery change, the dated sighting is worth more than any undated type reference.
