Key takeaways
- The 88 sits in the tank-locomotive band: the DRG reserved numbers 80 to 96 for tank locomotives in freight and shunting service.
- A collective number, not a standard design: under 88 the DRG grouped together inherited state-railway machines, not a new design of its own.
- How to recognise it: first tank or tender locomotive, then wheel arrangement, then the number.
- No longer in regular service: machines in this number group are historic vehicles, not working locomotives.
- The sub-class after the point separates the different design groups sharing the same number.

Identifying features
Is this really the class in front of you?
- Tank locomotive: no separate tender attached, supplies carried in side water tanks and a coal bunker by the cab
- Small, stocky build – markedly shorter than an express locomotive with a tender
- Number starts with 88, followed by a sub-class (88.0, 88.1 and so on)
- State-railway styling: riveted boilers, an open or minimal cab
- Runs equally well in both directions – typical for shunting and transfer duties
Updated: August 2026 – Class 88 isn’t a single vehicle but an organisational number from the early days of the Deutsche Reichsbahn-Gesellschaft. Understand it, and you understand the whole steam locomotive numbering system at once – and can then place any museum locomotive in seconds. This page explains what the 88 stands for, how to recognise tank locomotives, and how to research this area sensibly.

What is Class 88?
Class 88 is a collective number of the Deutsche Reichsbahn-Gesellschaft for tank locomotives in freight and shunting service. It wasn’t created at the drawing board but at the desk: when the DRG brought the very varied fleets of the former state railways into a shared system in the 1920s, it needed a number band for every vehicle category – and the 88 was one of the slots for smaller tank locomotives.
Operationally that means: this isn’t where you find express machines or big main-line locomotives, but workhorses for short distances. Shunting in stations, transfer runs between sidings and marshalling yards, branch-line duties. That’s exactly what tank locomotives are built for: short, agile, equally good in both directions, with no need to run round at the terminus.
Regular service ended decades ago. Today this number group is a subject for archives, specialist literature and vehicle collections – not the platform.
The DRG’s numbering system – and why the 88 sits where it does
The German steam locomotive numbering system is remarkably strictly organised. The class number tells you two things at a glance: what the locomotive was meant for and how it carries its supplies. That’s the key to everything else.
| Number band | Vehicle category | Design |
|---|---|---|
| 01–19 | Express passenger locomotives | Tender locomotive |
| 20–39 | Passenger locomotives | Tender locomotive |
| 40–59 | Freight locomotives | Tender locomotive |
| 60–79 | Passenger tank locomotives | Tank locomotive |
| 80–96 | Freight and shunting tank locomotives | Tank locomotive |
| 97 | Rack locomotives | Special design |
| 98 | Local-railway locomotives | Mostly tank locomotive |
| 99 | Narrow-gauge locomotives | Mostly tank locomotive |
The 88 sits in the tank-engine band for freight and shunting service, and at its lower end – where the smaller, lighter machines were placed. The further the number climbs within this band, the larger and heavier the machines tend to become: Class 92 gives you four-coupled shunting locomotives, and Class 94 five-coupled machines for heavy loads.
Directly above, at Class 89, sit the three-coupled shunting locomotives – the group where this principle shows most clearly.
The digit after the point – 88.0, 88.1 and so on – separates the sub-classes. That was necessary because half a dozen quite different state-railway designs often ended up under a single number. How to approach an unfamiliar locomotive systematically is described in the guide to identifying classes.
Recognising a tank locomotive: three looks are enough
Even without prior knowledge you can confidently place a locomotive in this category. The order matters – coarse features first, then fine detail.
Tender or no tender?
If a separate wagon with coal and water hangs behind the locomotive, it's a tender locomotive. If the water tanks sit at the sides of the boiler and the coal bunker is behind the cab, you're looking at a tank locomotive – and the band 60 to 99.
Count the axles
Count the large driving wheels linked by rods, and separately the smaller carrying axles. Three coupled axles are a C, four a D, five an E. Carrying axles ahead of or behind them are given as digits.
Infer the purpose
Large driving wheels point to passenger and express service, small wheels with many coupled axles to freight and shunting service. That almost always matches the number band.
A rule of thumb for the field
Design first, then wheel arrangement, then number. Anyone who starts with the number is stuck in poor light or from 100 metres away – design and wheel arrangement, by contrast, you can almost always see.
Learn to place wheel arrangements confidently
Log your observations directly in Traintrack and compare them later, at your leisure, with the class database.
Research instead of spotting: how to reach this area
For a number group with no regular service, the work shifts from the photo spot to research. These routes work:
- Photo archives and forum archives. Historic photographs are often the only source for classes withdrawn early. The overview of the Historic Railway section shows how to search large archive holdings sensibly.
- Museum depots and plinthed locomotives. Many early tank locomotives now stand as monuments or in depots; large collections such as the Deutsches Technikmuseum Berlin hold such state-railway designs in their fleets. You’ll learn the operator and location from the relevant societies, not from general lists.
- Events with vehicle displays. Museum festivals occasionally show vehicles otherwise kept behind closed doors. The guide to heritage railways and special services explains how to find dates like this.
- Specialist literature. For state-railway designs, printed material is often more accurate than anything freely available online.
The owner's house rules apply on museum grounds
Depots, engine sheds and storage sidings are operational railway land. Barriers are binding and track areas are off limits, even where a locomotive looks as if it hasn't moved in years. Ask at the entrance what's allowed instead of trying it yourself.
Photographically: what works with old tank locomotives
Static shots dominate in this area, because the vehicles are usually standing still. That’s no drawback if you approach it deliberately: a three-quarter view from a slightly lower viewpoint makes the stocky build look more powerful than a straight-on shot. Make sure the wheel arrangement and vehicle number stay legible in the frame – that’s what makes the photo identifiable later.
If a machine actually is under steam, different rules apply: backlight, the steam plume and the exhaust beat then become the real subjects. How to handle that technically is covered in the guide to steam-train photography.
Common mix-ups
It points to this number band if …
- the locomotive has no tender wagon behind it
- the water tanks sit at the sides of the boiler
- the wheels are small and the locomotive looks stocky
- the number begins with 8 or 9
Look more closely if …
- the locomotive has been rebuilt or carries markings from a later numbering scheme
- you only see one side and can't count the wheel arrangement fully
- the lettering comes from a museum operation and doesn't match the original condition
It doesn't belong in this band if …
- a separate tender wagon is attached – then you're in the range 01 to 59
- the locomotive has large driving wheels for high speed
- it's a narrow-gauge machine – the 99 was reserved for that
Verdict
Class 88 is a good example of a class number being more of an organisational term than a vehicle description on German steam locomotives. It reliably tells you that a tank locomotive for freight and shunting service is meant – and that logic is exactly what’s worth remembering. No regular service exists any more; anyone interested in this area works with archives, museum fleets and a good eye for design and wheel arrangement.
In brief
88 means: tank locomotive, freight and shunting service, a collective number for state-railway designs. No current vehicle, but the key to understanding the entire steam locomotive numbering system.

From the museum locomotive to the modern electric: with Traintrack you document every encounter neatly and find it again later.
Summary
- Class 88 belongs to the number groups the Deutsche Reichsbahn-Gesellschaft assigned to tank locomotives in freight and shunting service.
- It isn't a single, uniform design but an organisational number for very different machines inherited from the state railways.
- In the field you can recognise the vehicle type from its tank-engine design, wheel arrangement and stocky silhouette.
- Anyone wanting to understand this number range works with archives, museum fleets and specialist literature rather than timetables.
Frequently asked questions
What is Class 88?
Class 88 is a number group in the classification system of the Deutsche Reichsbahn-Gesellschaft. It sits in the band 80 to 96, reserved for tank locomotives in freight and shunting service. Grouped under it were machines inherited from the state railways – not a shared new design.
What does the number 88 mean in the DRG system?
The first digit roughly assigns the locomotive to a category, the second refines it. The groups of twenty are clearly divided: 01 to 19 express passenger locomotives, 20 to 39 passenger locomotives, 40 to 59 freight locomotives with a tender, 60 to 79 passenger tank locomotives, and 80 to 96 freight tank locomotives. The 88 sits firmly among the tank locomotives.
What's the difference between a tank locomotive and a tender locomotive?
A tank locomotive carries its coal and water on the vehicle itself – in side water tanks and a coal bunker behind the cab. A tender locomotive instead pulls its own tender wagon behind it. Tank locomotives are shorter, run equally well in both directions, and are therefore typical for shunting and branch-line service.
Do locomotives of Class 88 still run?
No, not in regular service. This number group belongs to the early fleets of the Deutsche Reichsbahn-Gesellschaft; scheduled service ended decades ago. Whatever still exists in this range at all is museum and collection stock, or only documented in photo archives.
What does the digit after the point mean, such as 88.0?
It denotes the sub-class. Because a single number often grouped together several quite different designs, the DRG separated them by the decimal and by the allocated number range. Two machines with the same class number can therefore differ substantially in technical terms.
How do I read the wheel arrangement of a steam locomotive?
Count from the front: carrying axles are given as digits, coupled driving axles as capital letters. C means three coupled axles, D four, E five. An apostrophe shows that the axle group is mounted movably in a bogie or truck. So 1'C1' means: one carrying axle, three coupled axles, one carrying axle.
Where can I find material on such old classes?
In photo archives, society collections and the archive sections of the big railway forums. Anyone who comes across a vehicle from this group finds it most likely as a plinthed monument, in a museum depot, or in historic photographs. Current sightings are the absolute exception here.
Is this number range worth anything to spotters?
As knowledge, yes; as a target to chase, hardly. Anyone who has once understood the DRG's numbering system can place, in seconds, any steam locomotive they come across at a heritage railway – that's the real benefit. You won't encounter Class 88 itself in operation.
