Key takeaways
- The 01 is the original standard locomotive: it began the Deutsche Reichsbahn-Gesellschaft's standardisation programme for steam locomotives in 1925.
- Identification feature number one is the wheel arrangement 2'C1' combined with a tender and only two outside cylinders.
- The number 01 itself is the information: the range 01 to 19 in the class scheme was reserved for express locomotives.
- 130 km/h and a high axle load restricted its use to well-built main lines.
- No vehicle remains in scheduled service: surviving 01s are museum locomotives, and their operational status changes with inspections and overhauls.

Identifying features
Is this really the class in front of you?
- Wheel arrangement 2'C1': two small leading axles at the front in a bogie, three large driving axles, one trailing axle at the rear
- Tender behind the locomotive – no side water tanks on the boiler
- Only two outside cylinders, one each on the left and right – no third one sits between the frame plates
- Large driving wheels, noticeably taller than the leading wheels – a hallmark of an express locomotive
- Class number starts with 01, followed by a three-digit running number
- Seen exclusively at special workings, museum operators and events
Updated: August 2026 – When people talk about “the 01”, almost everyone pictures the same thing: large driving wheels, tender, two outside cylinders, two small leading axles at the front. The Class 01 was the first standard locomotive of the Deutsche Reichsbahn and so the starting point for everything built afterwards in German steam locomotives. This page explains the numbering system behind it, the identification features, and how to catch a sighting today.

What is the Class 01?
The Class 01 is an express steam locomotive with a tender, built between 1925 and 1938 and numbered from 01 001 to 01 232. It has the wheel arrangement 2’C1’, works with two outside cylinders on superheated steam, and was rated for 130 km/h.
Its historical significance lies less in its technology than in its concept. After the founding of the Deutsche Reichsbahn-Gesellschaft, vehicles from eight different former state railways stood side by side – each with its own components, its own spare-parts stock, its own training. The 01 was the first answer to that: a deliberately standardised machine whose components matched those of other standard locomotives. Today no 01 remains in scheduled service; surviving engines are museum and special-train vehicles, whose boiler certificates are renewed at the Meiningen Steam Locomotive Works.
Understanding the class scheme
The number 01 is not a random label but a statement. The scheme introduced in 1925 assigned every steam locomotive class a fixed number range – anyone who knows it can roughly place any German steam locomotive.
| Number range | Class | Design |
|---|---|---|
| 01–19 | Express locomotives | Tender |
| 20–39 | Passenger locomotives | Tender |
| 40–59 | Freight locomotives | Tender |
| 60–79 | Passenger locomotives | Tank engine |
| 80–96 | Freight and shunting locomotives | Tank engine |
| 97 | Rack locomotives | Tank and tender engines |
| 98 | Branch-line locomotives | Mostly tank engines |
| 99 | Narrow-gauge locomotives | Mostly tank engines |
There are also sub-classes with a decimal, such as 01.10 or 01.5. These group together engines that differ significantly in technology from the base type – derived from the hundreds digit of their running numbers. The Class 01.10 is the three-cylinder further development, the Class 01.5 a later reconstruction by the Deutsche Reichsbahn in the East.
If you want to apply this principle to any vehicle, the guide to identifying locomotive classes helps with a fixed order in which to work through features.
How to identify a 01 in the field
Check the tender
If a separate tender with coal and water runs behind the locomotive, it's a tender locomotive. Water tanks on the sides of the boiler would instead indicate a tank engine – and that belongs in a completely different number range.
Count the axles
Two small leading axles at the front, three large driving axles in the middle, one trailing axle at the rear. That's 2'C1' – the signature of the express locomotive.
Count the cylinders
One cylinder each on the outside left and right, no third one in between: that's what separates the Class 01 from its three-cylinder sisters. A view from slightly ahead onto the frame shows it best.
Read the number
The number plate on the cab or the smokebox door settles it. 01 plus a three-digit running number up to 232 – then it checks out.
Driving wheel size as a shortcut
Express locomotives have strikingly large driving wheels, freight locomotives smaller but more numerous ones. If the wheels look noticeably taller than hip height and you count only three coupled axles, you're almost certainly looking at an express locomotive.
Keep an eye on special workings
Historic vehicles run rarely and at short notice – community reports are often the fastest source.
Where you can see a Class 01 today
Not on a route, but at an event. Scheduled steam operation is history; what’s left is run by societies, museum operators and foundations such as the Bavarian Railway Museum. Research therefore always runs through people and organisations, never through a timetable.
This order has proven effective: first the operator pages of heritage railways and societies, because that’s where it says which locomotive is actually operational. Then the events calendars – station festivals, anniversaries, vehicle shows and museum days are the typical occasions. Finally the forums and sighting channels, where short-notice cancellations, locomotive swaps and diversions appear first. A practical starting point is provided by the guide to finding special trains and special workings and the overview of heritage railways and their dates.
House rules apply on museum sites
At events and at museum operators, the operator decides which areas are accessible. Barriers are binding and non-negotiable. Tracks, turntables, engine sheds and stabling areas stay off-limits – even when an engine seems to be standing still. Shunting moves with steam locomotives happen slowly, but without warning.
Photo tips for express steam locomotives
Steam is its own subject photographically. Unlike with an electric locomotive, it’s not just the light that decides the shot, but also the weather and wind direction.
- Cold weather produces a lot of steam. It looks dramatic, but it can completely obscure the locomotive. In still, cold air it’s worth taking a viewpoint further ahead.
- A crosswind is your friend. It carries the plume out of the shot and leaves the boiler and motion gear visible.
- A short shutter speed for sharp connecting rods – or deliberately a longer one if you want to show motion. Either is a choice, not chance.
- The motion gear is the subject. A slightly angled shot shows cylinders, rods and wheels – exactly what a head-on shot loses.
The details, from equipment to choosing a location, are covered in the guide to photographing steam trains.
Common mix-ups
It points to the Class 01 when …
- you count the wheel arrangement 2'C1'
- a tender runs behind the locomotive
- only two outside cylinders are present
- the number plate starts with 01 and a running number up to 232
Look more closely when …
- the number suggests a decimal – then it could be a sub-class
- the boiler looks noticeably more modern than the rest of the engine
- you only see the motion gear from the side and can't check the cylinder count
It's not a 01 when …
- you count four or five coupled driving axles – those are freight classes
- there are water tanks on the sides of the boiler – then it's a tank engine
- the driving wheels are small and numerous
Its closest relatives are the lighter Class 03 with the same wheel arrangement but a lower axle load, and the three-cylinder further developments. From the freight side comes the five-coupled Class 44, which you can hardly confuse with a 01 once you’ve counted the axles.
Verdict
The Class 01 is the best entry point into German steam locomotive classes, because it makes the whole system visible: the number tells you the purpose, the wheel arrangement tells you the design, the cylinder count separates the sub-classes. Once you understand these three levels, you can place unfamiliar engines too. You can still see them only at special workings and museum operators such as the German Steam Locomotive Museum Neuenmarkt-Wirsberg – usually with an audience, in that case.
In short
2'C1', tender, two outside cylinders, number 01: that's the first German standard express locomotive. There's no scheduled service any more – you go looking via societies, museum operators and events calendars.
Summary
- The Class 01 began the standardisation of German steam locomotive construction from 1925 – before that, every former state railway ran something different.
- It is a 2'C1' tender locomotive with two cylinders, built for fast passenger trains on main lines.
- It differs from its sister classes mainly in cylinder count and the lack of a streamlined past.
- Today the 01 is a purely historic vehicle; anyone wanting to see it researches special workings and museum operators.
Frequently asked questions
What is the Class 01?
The Class 01 is an express steam locomotive with a tender and the wheel arrangement 2'C1'. It was the first so-called standard locomotive of the Deutsche Reichsbahn-Gesellschaft and was built between 1925 and 1938. It was rated for 130 km/h and so for the fastest passenger trains of its time.
What does the number 01 mean in the class scheme?
The scheme introduced in 1925 divided steam locomotives into number ranges by purpose. 01 to 19 were express locomotives with a tender, 20 to 39 were passenger locomotives, 40 to 59 were freight locomotives. Tank locomotives started at 60. So the class number reveals the intended use before you've even seen the vehicle.
How do I tell the Class 01 apart from the 01.10?
By the cylinder count. The Class 01 is a two-cylinder engine with two outside cylinders, the 01.10 a three-cylinder engine with the third cylinder inside. From the outside you can tell by the additional valve gear and the altered frame structure at the front. The number plate settles it for good.
Does a Class 01 still run in scheduled service?
No. Scheduled steam operation ended in Germany long ago. Surviving Class 01 locomotives belong to museums, societies and heritage operators and run exclusively in front of special trains or stand on display. Which locomotive is currently operational changes with boiler inspections and overhauls.
Why couldn't the 01 run everywhere?
Because of its high axle load. Three driving axles had to carry the entire weight of the heavy machine, which required sturdy track. It wasn't cleared for branch lines with lighter track – lighter classes were used there instead.
How do I find out when a 01 is running?
Through the operators. Heritage railways, societies and heritage operators publish their own dates; add to that event calendars and community forums, where short-notice changes appear first. There are no fixed timetables – every working is a one-off event.
What's the best way to photograph a steam locomotive?
Differently from an electric locomotive. Wind direction and temperature are decisive, because the steam plume can dominate the shot or hide the locomotive. A slightly angled viewpoint with the sun behind you and a short shutter speed for the connecting rods are the usual starting point. On museum sites, house rules and barriers always apply.

Class 01.10
The Class 01.10 was the three-cylinder development of the 01: 55 engines, streamlined from the factory, rated for 150 km/h. Today only seen as a heritage vehicle.
Steam/specialDR Class 01.5
The Class 01.5 was created by rebuilding the old standard Class 01 at the Meiningen works: new boiler, modernised cab, some engines converted to oil firing – today they are museum vehicles only.
Steam/specialDRG Class 03
The Class 03 was the lighter sister of the 01: same wheel arrangement 2'C1', same top speed, but a lower axle load – so it could run on far more lines.
Steam/specialDB Class 41
Class 41 was the fast freight locomotive among the standard-design locomotives: 366 engines, wheel arrangement 1'D1', 90 km/h. Today it only runs as a museum and special-train locomotive.
Steam/specialDR Class 42
The Class 42 was the heavy war locomotive KDL 3: 1,061 built, 1'E wheel arrangement, constructed from 1943. Today it survives only as a preserved museum vehicle.
Steam/specialDR/DB Class 44
The Class 44 was the heavy freight locomotive of the standard-design classes: five coupled axles, three cylinders, around 1,989 built. The "Jumbo" now only runs in preservation.
Who is behind it
Groups, brands, manufacturers and operators – who owns whom and how to recognise them out in the field.
Bayerisches Eisenbahnmuseum
The Bayerisches Eisenbahnmuseum in Nördlingen combines two things that rarely go together: one of Germany's largest vehicle collections and its own line service. Its base is a preserved motive power depot with a roundhouse and turntable in the Nördlinger Ries.
ManufacturerDampflokwerk Meiningen
In Meiningen stands the works that operational steam in Germany depends on. Here complete steam locomotive boilers are built from scratch, here major overhauls are carried out – and here it's decided which historic machine will still be under steam in the years ahead.
Heritage railwayDeutsches Dampflokmuseum Neuenmarkt-Wirsberg
The Deutsches Dampflokmuseum sits in a former steam locomotive depot at the foot of the Schiefe Ebene incline. It doesn't run trains itself – it's a collection – but right outside the door lies one of Germany's best-known steep gradients, still carrying scheduled services today.
Heritage railwayStoom Stichting Nederland
The Stoom Stichting Nederland owns no heritage line of its own. It runs its steam trains over the normal Dutch network – among freight trains, Intercity services and Sprinters. That makes it the exception among the country's heritage operators, and it changes everything about how you photograph it.

Nürnberg Hauptbahnhof
Nuremberg is one of the few big German stations where high-speed traffic, regional services and heavy freight genuinely run side by side. Add a museum landscape within walking distance – and a marshalling yard that sorts half of southern Germany's freight traffic.
Mountain lineSchiefe Ebene near Marktschorgast
The Schiefe Ebene between Neuenmarkt-Wirsberg and Marktschorgast is Germany's best-known steep incline – and one of the few places where steam locomotives can still be seen regularly at full load. The German Steam Locomotive Museum stands at the foot of the ramp.
