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?

Tick off everything that applies to the vehicle you are looking at.

  • 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.
