Class 89.3

Updated: August 2026 – The designation Class 89.3 looks at first glance like a class of its own, but it’s something else: a sub-class. Anyone who understands how such numbers are built up can place any historic steam locomotive from its markings alone – and knows straight away whether they’re looking at a shunter, a main-line machine or an express locomotive. This page explains the system and places 89.3 within it.

What is Class 89.3?

Class 89.3 is a sub-class within Class 89 – that is, within the group of three-coupled tender locomotives that the Deutsche Reichsbahn-Gesellschaft ran for shunting and light freight duties. Everything that applies to Class 89 as a whole therefore applies technically here too: wheel arrangement C, no carrying axles, supplies carried on the vehicle rather than in a separate tender, short wheelbase, low speed.

The addition “.3” marks its own design group. It arose from the plain necessity of telling apart several technically different designs grouped under one shared class number. When the DRG unified the vehicle fleets of the former state railways in the 1920s, machines of very different origin ended up under each type number.

There has been no regular service for decades. This area is a subject for archives, specialist literature and museum collections – not the platform. Where a small tender locomotive of this size still runs at all, a heritage society keeps it going – such as the Delmenhorst-Harpstedter Eisenbahn-Freunde, who run their train on summer Sundays over a line otherwise used purely for freight.

How to read a steam locomotive number correctly

The most important point first: the notation with a point doesn’t appear on the locomotive. On the vehicle you’ll find a number like 89 3xx. The sub-class follows from which number block the running number falls into.

You’ll find the same logic – type first, then subgroup, then individual vehicle – in a modernised form in today’s European numbering system. How that works in detail is explained in the article on the UIC number and its check digit.

What the number band reveals about the intended use

The class number of a German steam locomotive isn’t a running count but a statement about its intended use. That’s what makes it so useful.

Number band	Type	Design	What that means in service
01–19	Express passenger locomotives	Tender (separate)	large driving wheels, high speed
20–39	Passenger locomotives	Tender (separate)	medium-sized wheels, main-line service
40–59	Freight locomotives	Tender (separate)	many coupled axles, high tractive effort
60–79	Passenger tender locomotives	Tender locomotive	local services, push-pull operation without running round
80–96	Freight and shunting tender locomotives	Tender locomotive	short distances, shunting and transfer duties
97	Rack locomotives	Special design	steep gradients with a rack rail
98	Local railway locomotives	mostly tender locomotives	branch lines with low axle load

89.3 clearly sits in the shunting bracket. Anyone wanting to see the same task carried out with more coupled axles will find it in Class 92 with four, and in Class 94 with five coupled axles.

Research routes: how to get to grips with such an old group

Without regular service, the work shifts from the photo spot to source research. These four routes are reliable:

• Forum archives and historic sections. These hold posts, photo series and discussions on state-railway designs that don’t turn up anywhere else. The overview of the Historic Railway section shows how to search collections like these.
• Society and museum registers. If a vehicle has survived, the route goes via its operator. Their information is more up to date than any general list.
• Printed vehicle registers. For renumbering plans and design groups, specialist literature is still the most accurate source.
• Monument and depot locations. Many early shunting locomotives now stand immobile – as a monument, in a depot, or as a source of spare parts.

One point that’s easy to overlook with old numbers: vehicles were renumbered several times over their lives. A machine might have started out as a state-railway locomotive with a class mark, received a Reichsbahn number in the 1920s, later been handed over to a private or industrial railway and relabelled there again – and in the museum it may end up carrying its oldest livery once more. For research this means one and the same vehicle can be documented under several designations. Anyone tracing a lead should therefore search for all known numbers in parallel and note in their own archive which marking was actually on the vehicle at the time a photograph was taken.

Photography: documenting vehicles rather than staging them

With machines in this category, the documentary value usually outweighs the artistic one. If you get a vehicle from this area in front of your lens, think in terms of evidence:

A clean side view shows the wheel arrangement in full and makes the shot usable for reference later. A close-up of the number plate confirms the identity. A three-quarter view from a low viewpoint delivers the shot you’ll actually want to show. Anyone with all three won’t have to guess later which locomotive it actually was.

If steam is actually involved, the priorities change: backlighting, exhaust beats and the steam plume become the subject. The technique for that – exposure, viewpoint, timing – is covered in the guide to steam train photography. On society premises, the owner’s house rules apply throughout: barriers are binding, tracks and workshop areas are off-limits.

Common mix-ups

Conclusion

Class 89.3 is less a vehicle than an example of just how precisely the German steam locomotive numbering system works. Two digits state the type and design, the running-number block separates the design groups, and the rest identifies the individual vehicle. Once you’ve got that down, you can read any historic locomotive number like a sentence – and that’s the real value of this number range, because you won’t encounter it in service any more.
