MaK 650 C

Updated: August 2026 – A shunting locomotive moves off, the cab is empty, and alongside the track walks an operator with a box strapped to their chest: this scene is now everyday reality at many industrial and private-siding railways. The MaK 650 C represents the generation of vehicles that went through this change. This page explains the type code and shows how to spot remote-control operation from the outside.

What is the MaK 650 C?

The MaK 650 C is a three-axle diesel locomotive for shunting and industrial railway service from Maschinenbau Kiel’s type programme. The type code follows the manufacturer’s own system: the number denotes engine power in metric horsepower, and the letter C denotes the three coupled driving axles in a rigid frame.

Within the UIC type codes it belongs to group 98 for diesel shunting and light locomotives, as distinct from 92 for diesel main-line locomotives. Vehicles in this group spend their working lives on industrial, port and siding tracks, such as those operated by RP Eisenbahn in the Rhineland – and have repeatedly been adapted to new operating patterns there over the decades. Radio remote control is the most striking of these adaptations.

Spotting remote-control operation in the field

Not every shunting locomotive is remote-controllable, and you can’t always tell at a glance. Four observations, though, reliably lead to the answer.

You’ll spot such details best with a telephoto lens from a safe distance – the guide to the best telephoto lens for railway photography covers which focal lengths make sense for this.

Where it fits into railway operations

Radio remote control has fundamentally changed the way shunting work is carried out. This comparison shows what’s different for spotters.

Feature	Classic shunting operation	Remote-control operation
Cab occupancy	Driver in the cab	Cab can remain empty
Communication	Hand signals and radio messages	Direct control by the shunter
Visible feature on the vehicle	No extra equipment needed	Aerials, indicator light, add-on cabinets
Movement sequence	Coordination between two people	One person controls and observes
Recognisable to onlookers	Driver visible in the window	Often no personnel visible in the vehicle

Comparable vehicles in the same programme are the MaK 450 C with the same wheel arrangement and the four-axle MaK 650 D. How MaK implemented the same wheel arrangement in the later G programme is shown by the MaK G 700 C.

Spotting: sequences rather than single shots

Shunting operations are more rewarding for photographers than main-line traffic, because they repeat and unfold slowly. Instead of waiting for the one moment a train passes, you can document a whole work sequence.

• Choose your position beforehand. A fixed viewpoint overlooking the transfer track yields more shots over an hour than constantly moving around.
• Series rather than single shots. Positioning wagons, coupling, running round – the sequence tells the story of the operation.
• Use a long focal length. It keeps you well away from the track while compressing the layout of the tracks in the frame.
• Secure the number. An extra telephoto shot of the data panel makes the sighting verifiable.

How to plan such sessions and which times of day are worthwhile is described in the guide to spotting at marshalling yards. Which distances to keep is explained in the article on safe distances at the track.

How a transfer working runs

Anyone wanting to understand what a shunting locomotive does all day should watch a transfer working from start to finish at least once. The sequence is similar at almost every private siding – and because it repeats daily, it can be planned for. Municipal operators such as Bahnen der Stadt Monheim work to exactly this pattern too.

Delivery. A train from the public network brings wagons to the transfer yard and sets them down on a designated track. The wagons stay there until the connecting operator collects them.

Handover. The works locomotive approaches the group of wagons, couples up and takes them over. Before departure a brake test and wagon inspection are required – this is the part that looks most like standstill from outside, yet is still active operation.

Delivery into the works. The group is hauled into the plant and distributed to the loading points there. This is where the real shunting work happens: setting wagons down, running round, and remarshalling.

Return. Loaded or unloaded wagons travel the same route back and are set out on the transfer track ready for the network.

For spotters the handover is the most interesting part, because it mostly takes place at the transfer track – the point where the site is most likely to be visible from public land. Once you know this rhythm, you know when a visit is worthwhile and don’t have to rely on luck.

This is exactly the phase where radio remote control comes into its own: the same operator can carry out coupling, the brake test and the shunting move. That’s why you often see a locomotive at modern private sidings that appears to move on its own – one more reason to treat any vehicle movement as possible at any time.

Common mix-ups

Conclusion

For your own documentation it’s worth noting equipment features separately from the type. The type describes what the vehicle is; aerials, indicator lights and add-ons describe how it’s used today. Together the two give a picture that goes well beyond a bare type designation – and one that can be checked again at a later encounter.

The MaK 650 C is a good example of how industrial locomotives are never static objects. The basic type stays recognisable for decades – three axles, rod drive, compact build – while its equipment and mode of operation change. Aerials and indicator lights aren’t just technical details here; they tell you how work is done at this location today.
