Key takeaways
- The 44 is the heavy freight locomotive of the standard-design classes: around 1,989 built, with five coupled axles.
- The decisive feature is the three-cylinder engine – it distinguishes it from the two-cylinder Classes 50 and 52.
- 043 and 044 are the same class: the Bundesbahn split it after 1968 between oil- and coal-fired locomotives.
- The nickname Jumbo came from the crews and describes the size and power of the locomotives.
- No regular service any more: whatever runs today runs as a heritage or preserved locomotive.

Updated: August 2026 – Five coupled axles, a high-mounted boiler and a third cylinder working between the frame plates: the Class 44 was the strongest standard freight locomotive among Germany’s standard-design classes. Around 1,989 locomotives were built from 1926, or from 1937 in the main series. This page shows you how to recognise them, what the three-cylinder engine means, and how to find a preserved locomotive today.

What is the Class 44?
The Class 44 is a heavy freight tender locomotive with the wheel arrangement 1’E and three cylinders. The first locomotives were built in 1926, the large series ran between 1937 and 1949; a total of around 1,989 locomotives were built. Maximum speed was 80 km/h, with early versions limited to 70 km/h.
Crews simply called it the Jumbo. It hauled the heaviest freight trains on the main lines and remained in service right up to the end of steam traction in Germany. After the 1968 computer renumbering, the Deutsche Bundesbahn classified the coal-fired locomotives as 044 and the oil-fired ones as 043. Today there’s no scheduled service left – preserved locomotives are heritage vehicles, including some at the Deutsches Dampflokmuseum Neuenmarkt-Wirsberg.
The three-cylinder engine: the feature that settles it
Classes 50 and 52 also have five coupled axles. What makes the 44 unambiguous is the engine.
Count the cylinders
Two cylinders sit visibly outside on the frame plates. On the 44, a third is added between them, working on a cranked driving axle.
Listen to the exhaust beat
A two-cylinder engine produces four exhaust beats per wheel revolution, a three-cylinder one produces six. The sound is therefore more even and less pounding.
Keep the front in view
Viewed from the front, you can often spot the additional smokebox door arrangement and the differing layout beneath the buffer beam.
The advantage of the three-cylinder design lies in smoother running: the force is distributed more evenly over the wheel rotation, which is easier on the track. The disadvantage is higher maintenance effort – one reason why the more simply built Class 50 was built in greater numbers. How to work through such features systematically is explained in the guide to identifying classes.
The order for identification
Count the coupled axles first, then the carrying axles, then the cylinders. The first two steps work from a great distance, the third needs proximity or a telephoto lens – but it's what decides between the 44 and its two-cylinder sister classes.
Placing it in service: the family of 1’E freight locomotives
Germany had several five-coupled freight classes that differed in build complexity and operating profile. This overview places them.
| Class | Cylinders | Character | Typical use back then |
|---|---|---|---|
| 44 | three | elaborate build, high tractive effort | heaviest freight trains on main lines |
| 50 | two | low axle load, universal | freight and passenger trains down to branch lines |
| 52 | two | wartime design, simplified | mass traffic under wartime conditions |
| 42 | two | heavy wartime design | heavy trains on lines that could bear them |
| 41 | two, 1’D1’ | faster, four coupled axles | express and parcels traffic |
The table shows the actual thinking behind the class scheme: it’s not size that decides the number range, but the purpose. All the classes named fall between 40 and 59 – the range for tender freight locomotives. The faster variant with four coupled axles is the Class 41, the most numerous wartime design the Class 52.

Spotting and photography: what matters with the 44
The 44 is a rewarding subject, because its length and five coupled axles work well in a side-on view. Three practical points:
- Side view rather than a frontal shot. The engine with five coupled axles is the unique selling point. An angle of 30 to 45 degrees shows the front and the engine at once.
- A dark background for the steam plume. Against a bright sky, the steam disappears. Wooded slopes, cuttings or buildings behind the locomotive bring it back into the picture.
- Make the most of cold air. In low temperatures, the steam condenses more strongly. Winter special trips therefore regularly produce the more striking photos.
The full technique is covered in the guide how to photograph steam trains. To find out about running dates at all, the overview on heritage railway research helps – running days and events surface there early. And because encounters with this class are rare, it’s worth keeping a properly maintained sightings logbook with number, date and occasion.
Museum grounds are not public space
House rules and barriers apply at heritage railway stations and during special trips. Tracks, engine sheds, turntables and workshop areas must not be entered, and staff instructions are binding. Stick to designated viewing points or publicly accessible areas; the basic rules are set out in the article on the safety distance at the track.
What the 1968 computer renumbering means
Anyone comparing older and newer sources on the Class 44 inevitably stumbles across two numbering worlds. The reason is a pure administrative decision.
Until 1968, the Deutsche Bundesbahn classified its steam locomotives with a two-digit class number and a separate running number – for example 44 1234. With the switch to electronic data processing, a fully machine-readable scheme was needed. The two-digit class number became a three-digit class number, with the leading digit coding the vehicle type as well. Steam locomotives were given a leading zero.
Since renumbering was happening anyway, the Bundesbahn used the opportunity to separate build states that had previously sat within a single class:
- 044 became the number for the coal-fired locomotives.
- 043 became the number for the locomotives converted to oil-firing.
Nothing changed technically as a result of the renumbering. In practice, that means a locomotive appearing in a 1965 book as 44 xxx may be labelled 043 or 044 in a 1972 photo – it’s the same vehicle. With preserved heritage locomotives, there’s the added factor that societies deliberately restore their locomotives to a particular period condition. So always note the number that’s actually on the vehicle, not the one you expect.
Common mix-ups
It's the 44 if …
- you count five coupled axles with a single carrying axle ahead
- a third cylinder sits between the frame plates
- the locomotive looks especially long and powerful
- the number starts with 44, 043 or 044
Look more closely if …
- you can't judge the cylinder count from your viewing angle
- the tender has no coal bunker structure – then it's an oil-fired locomotive
- the locomotive is running with foreign markings or without number plates
It's not a 44 if …
- only two cylinders are present – then 50, 52 or 42 are more likely
- you count only four coupled axles and see a carrying axle at the rear
- the vehicle has side water tanks instead of a tender
Conclusion
The Class 44 can be reliably identified in two steps: count five coupled axles, then look for the third cylinder. That three-cylinder engine alone separates it from its two-cylinder sister classes and at the same time explains why it was more powerful, but also more complex. In regular service it’s long since history – as a heritage locomotive, it remains one of the most impressive German steam locomotives.
Quick verdict
Five coupled axles plus three cylinders: that's the Class 44, the Jumbo. Numbers with 043 and 044 belong to the same family and only distinguish the type of firing. Sightings today are purely heritage events.
Summary
- The Class 44 was the backbone of heavy freight traffic in Germany for decades.
- Its three-cylinder engine is a feature you can verify in the field and reliably separates it from similarly large freight classes.
- The designations 043 and 044 come from the 1968 computer renumbering and distinguish oil-firing from coal-firing.
- Anyone wanting to see a 44 should research heritage railways, preservation societies and special-trip calendars.
Frequently asked questions
How do I reliably recognise the Class 44?
By two things: the wheel arrangement 1'E with five coupled driving axles and one carrying axle ahead – and the three-cylinder engine. Look under the boiler: if a third cylinder works there between the frame plates, the locomotive is unambiguously identified against the two-cylinder Classes 50 and 52.
What does three-cylinder mean on a steam locomotive?
A three-cylinder locomotive has three cylinders: two outside on the frame plates and one inside between them. That distributes the force more evenly over the wheel rotation, runs more smoothly and reduces impacts on the track. The price is a more complex, more maintenance-intensive engine.
How many Class 44 locomotives were built?
Around 1,989 locomotives were built. The first arrived as early as 1926, with the large series following from 1937 to 1949. After 1945, the fleet was split across several railway administrations, with the largest share going to the Deutsche Bundesbahn.
What's the difference between Class 043 and 044?
Both designate Class 44 locomotives after the Deutsche Bundesbahn's 1968 computer renumbering. The 044 were coal-fired, the 043 oil-fired. Visually, you can spot the difference at the tender: oil-fired locomotives lack the open coal bunker structure, replaced instead by a closed tank.
Why is the Class 44 called Jumbo?
The nickname came from the operating crews and refers to the size and tractive effort of the locomotives. With five coupled axles and three cylinders, the 44 was the strongest standard freight locomotive of its time and hauled trains that would otherwise have needed two locomotives.
What does the 44 number range indicate?
The Deutsche Reichsbahn-Gesellschaft's class scheme is organised by purpose: 01 to 19 express passenger locomotives with tender, 20 to 39 passenger locomotives, 40 to 59 freight locomotives, 60 to 96 tank locomotives, 97 to 99 rack, branch-line and narrow-gauge locomotives. So the 44 is already identifiable as a heavy freight locomotive from its number alone.
Does the Class 44 still run today?
Not in regular service. Several locomotives are preserved, some of them operational – some abroad. Runs take place exclusively as special trips or in heritage railway operation and depend on boiler certificates and workshop capacity.
How do I find out where a 44 is located?
Via the vehicle lists of railway museums, the pages of operating societies, and the historical sections of major railway forums. Fleets change through sales, overhauls and loans – so always check the current status directly with the operator rather than an older list found online.
