Henschel DHG 500 C

Updated: August 2026 – Anyone getting into shunting locomotives quickly runs into a jumble of letters and numbers: DHG, MG, ML, MB, DG. The Henschel DHG 500 C is a good vehicle for cracking this system, because part of its code works the same way at every German works.

What is the Henschel DHG 500 C?

The Henschel DHG 500 C is a three-axle, diesel-hydraulic shunting and works locomotive with cardan-shaft drive from the type programme of Henschel & Sohn in Kassel. DHG names the power path, 500 the engine output in horsepower, C the three coupled driving axles in a rigid frame.

Operationally, it’s classed by the type code 98 in the twelve-digit European vehicle number: diesel shunting and light locomotive. Its counterpart is 92 for diesel main-line locomotives. For spotters, these two digits are the single most valuable organising feature there is, because they’re readable without specialist knowledge and immediately halve the search space.

The type code: what works the same everywhere

Manufacturer codes look arbitrary, but that’s only partly true. Break them into three building blocks and it becomes clear which part transfers and which doesn’t.

Building block	Example DHG 500 C	Applies across manufacturers?	What it tells you
Leading letters	DHG	no, works-specific	drive and power transmission per the works’ own logic
Number in the middle	500	yes, usually	engine output in PS, i.e. the output class
Capital letter at the end	C	yes	number of coupled axles and running-gear type
Doubled letter	BB, CC	yes	two bogies, each with that many axles
Lower-case suffix letter	a, b	no, works-specific	variant within the family

That gives a very practical rule: you can read the number and the final letter directly on almost every German industrial locomotive. The leading letters you have to look up per manufacturer, and you must never carry them over from one works to another. A G doesn’t mean the same thing everywhere, and an M certainly doesn’t.

Why the wheel arrangement is the most robust feature

Of all the components, the final letter is the only one you can check in the field without reading a plate. It follows the general wheel-arrangement notation that also applies to main-line locomotives.

The systematic order for identification – from coarse to fine feature – is described generally in the guide to identifying locomotive classes; it works just as well for industrial locomotives as for state-railway classes.

The neighbours in the same output class

Almost every German works had a type in this size bracket in its programme – each with its own code, its own frame and its own gearbox. None of them is identical, but plenty are comparable. Individual examples of these machines survive at heritage railways such as the Hespertalbahn in the Ruhr area.

The MaK G 500 C represents the Kiel tradition with its own G series, the Krauss-Maffei M 500 C the Munich approach with an entirely differently structured code, and the Gmeinder D 500 C the Mosbach approach. All three carry the same number and the same final letter – and that’s exactly what shows how far the transferable part of the code reaches, and where it stops.

For your sighting, that means: always note the manufacturer’s name too. “500 C” alone isn’t an identification, it’s a class. How to write up sightings so others can follow them is covered in the guide to reporting sightings.

Tackling an unfamiliar manufacturer code

Sooner or later you’ll be standing in front of a locomotive whose code you don’t recognise. Instead of guessing, work through the code back to front – the transferable part first.

The decisive point: you look up the leading letters, you don’t infer them. It’s perfectly fine to close out a sighting with “three-axle shunting locomotive, type line photographed, manufacturer X” and add the answer later. A wrong guess is worse than an open question – especially because manufacturer codes weren’t always kept consistent over the decades, even within a single works.

Observing: location, safety, number

Three-axle shunting locomotives work wherever groups of wagons are moved – on works sites, in ports and on private sidings. The shunting staff for this are often supplied by service providers such as KSV Kompetenz für Schienengebundene Verkehre. For observers, the interesting moment is the handover to the public network, because the vehicle then briefly becomes visible from outside.

If a vehicle number is legible, a second look pays off: besides the type code, it also contains the country code, serial number and check digit. How the twelve digits are structured is explained in the article on reading the UIC number and its check digit.

Common mix-ups

Verdict

The Henschel DHG 500 C is less a single vehicle than a key: once you can break down its type name, you’ll read the codes of MaK, Krauss-Maffei, Gmeinder and O&K a lot faster too. The number and final letter transfer, the leading letters don’t – and the type code 98 tells you where to even start looking.
