Key takeaways

  • The P 8 is the most-built German passenger locomotive: around 3,900 examples, designed in 1906 by Robert Garbe.
  • Fastest way to identify it: two-axle bogie at the front, three coupled axles behind it, no trailing axle at the rear.
  • The Prussian P 8 and Class 38 are the same locomotive – the class designation only arrived with the Deutsche Reichsbahn-Gesellschaft from 1925.
  • Regular service ended in 1972 and 1974 respectively; today only preserved museum examples still run.
  • Most likely to be confused with other three-coupled-axle tender locomotives, such as the newly built Class 23.10.

Updated: August 2026 – Hardly any German steam locomotive has seen as many stations as the Prussian P 8, listed by the Deutsche Reichsbahn-Gesellschaft as Class 38.10–40. Around 3,900 examples, built from 1906, in service into the 1970s. This page shows you how to identify it beyond doubt, why it carries two names, and how you can still encounter one of the preserved examples today.

What is Class 38, or the Prussian P 8?

Class 38 is a passenger tender locomotive with the 2’C wheel arrangement, designed in 1906 by Robert Garbe for the Prussian state railway. A total of around 3,900 examples were built – putting it among the most-built passenger steam locomotives in the world. It was rated for 100 km/h and worked with superheated-steam technology, which made it unusually economical for its time.

Operationally, the P 8 was the all-purpose tool of passenger service: local trains on branch lines, semi-fast trains on main lines, and freight duties when needed. Regular scheduled service ended in 1972 with the Deutsche Reichsbahn and in 1974 with the Deutsche Bundesbahn. What still runs under steam today are individually preserved museum examples, such as those held by the DGEG Railway Museum Bochum-Dahlhausen.

From class letter to class number

The double name P 8 / Class 38 is no accident, but a piece of administrative history. Until 1920 every locomotive belonged to a state railway – Prussia, Bavaria, Saxony, Baden and others each assigned their own class letters. On the Prussian state railway, P stood for passenger locomotive, G for freight locomotive, S for express locomotive and T for tank locomotive. The number after it was a running design number, not a performance figure.

With the founding of the Deutsche Reichsbahn-Gesellschaft, a unified scheme emerged from 1925 that assigned every design a class number:

Purpose from the number range

01 to 19 are express locomotives with a tender, 20 to 39 are passenger locomotives, 40 to 59 freight locomotives. Everything from 60 upwards is tank locomotives.

Sub-class as a design distinction

The P 8 landed in the range 38.10 to 38.40. Other sub-classes of the 38 belonged to entirely different state-railway designs.

Wheel arrangement as a second layer

Letters stand for coupled driving axles, figures for trailing axles, and the apostrophe for a bogie. That describes 2'C unambiguously.

Anyone who knows this pattern can also roughly place unfamiliar steam locomotive numbers. The basic approach to identifying vehicles is explained in the guide to identifying classes.

The decisive look on a P 8

Check what comes behind the driving axles. On the P 8, nothing does – the cab sits right above the end of the frame. That immediately rules out locomotives with a trailing axle at the rear.

Where it fits into railway operations: what a 2’C passenger locomotive delivered

The design explains the deployment. Three coupled axles give enough tractive effort for medium-weight passenger trains, and the leading bogie allows higher speeds than a rigid leading axle. For heavy freight trains, though, it lacks adhesive weight – that’s what five-coupled classes were for.

Design feature What it means Consequence for deployment
Three coupled driving axles moderate tractive effort, moderate axle load passenger and semi-fast trains, even on weaker lines
Leading bogie (2’) smooth running at higher speed rated up to 100 km/h
No trailing axle compact frame, limited firebox sufficient for passenger trains, not for sustained maximum load
Tender large coal and water supply long runs without replenishing
Superheated-steam engine better efficiency economical in everyday service

This combination is why the P 8 lasted so long: it was best at nothing, but useful for almost everything. Equally versatile among the freight classes was the Prussian G 8.1 as Class 55, which applied the same principle to freight service.

How to find an operational P 8

The search doesn’t run through the timetable but through operators – from large museums to heritage railways such as the Hessencourrier. Three lines of research lead to the goal:

  • Railway museums and heritage railways. Where a P 8 is based is usually listed on the relevant museum’s vehicle roster. Whether it’s operational is a separate question – far from all preserved examples are under steam.
  • Event and special-train calendars. Large steam locomotives are announced for anniversaries, museum festivals and special trains. The guide to special trains and special services describes where these dates appear first.
  • Historic sections on railway forums and community reports. The overview on researching historic railways shows how to draw reliable information from forum posts. It’s also worth checking live community sightings if you’re planning at short notice.

Take the site's house rules seriously on museum grounds

Engine sheds, turntables, track fields and workshop areas are operational railway land, not public space. Barriers and staff instructions apply without exception, and walking on tracks is out of the question. What clearance to keep from the track in general is explained in the article on safety distance from the track.

For the photo itself, steam locomotives follow their own logic: steam needs a dark background and cool air, the motion gear is more appealing with a slightly longer shutter speed than frozen solid, and the choice of vantage point matters more than the equipment. Details on this are in the guide on how to photograph steam trains.

One point that matters especially with the P 8: museum locomotives are regularly restored to a particular historical period, as shown for instance by the vehicles at the Bavarian Railway Museum in Leipzig. Because of this, the same locomotive can appear, depending on its restoration state, either as a Prussian P 8 with state-railway markings or as a Class 38 with Reichsbahn or Bundesbahn lettering. Anyone documenting a sighting should therefore note which lettering the vehicle actually carried – not the one given in an older book. It’s exactly this distinction that makes a photo placeable years later.

It’s also worth looking at the tender. Because tenders and locomotives were swapped repeatedly over the decades, the combination doesn’t always match the original as-delivered condition. That doesn’t matter for identifying the class – wheel arrangement and number decide that – but it does matter for clean documentation.

Common mix-ups

It points to a P 8 if …

  • a two-axle bogie runs at the front
  • three coupled driving axles follow, with no further trailing axle after them
  • the boiler and frame show visible rows of rivets
  • the running number begins with 38

Look more closely if …

  • the locomotive is standing at an angle from behind and you can't see the leading bogie
  • smoke deflectors have been retrofitted and change the silhouette
  • a vehicle abroad carries a similar design – there were many replica and reparations locomotives

It is not a P 8 if …

  • a further trailing axle sits behind the driving axles
  • you count four or five coupled axles
  • the locomotive has side tanks along the boiler instead of a tender

The most obvious mix-up is the Deutsche Reichsbahn’s Class 23.10: also three coupled axles, but with a single trailing axle at each end and a smooth, welded construction. With freight classes such as the Prussian G 10 as Class 57.10–35, the number of coupled axles settles it immediately.

Conclusion

The Prussian P 8 is the classic among German passenger steam locomotives – and, thanks to its clear wheel arrangement, one of the easiest to identify. Bogie at the front, three coupled axles, nothing behind them, number beginning with 38: that’s all it takes. That it carries two names is simply down to the switch from state-railway class letters to the Reichsbahn’s class scheme.

In short

Bogie at the front, three coupled axles, no trailing axle at the rear: that's the P 8, alias Class 38. Today it only runs in museum service – find dates via heritage railways, societies and special-train calendars.

Summary

  • The Prussian P 8 was, for decades, the backbone of German passenger service and ran on practically every railway administration in central Europe.
  • Spotting it in the field comes down to the leading bogie and the absence of a trailing axle.
  • The shift from the state-railway designation P 8 to Class 38.10–40 explains why the same locomotive carries two names in sources.
  • Anyone wanting to see a P 8 should plan around heritage railways and special trains – it doesn't appear in the regular timetable.

Frequently asked questions

How do I reliably identify a Prussian P 8?

By the wheel arrangement 2'C: a two-axle bogie at the front, followed by three coupled driving axles and no further trailing axle. Add to that the tender and the visible rows of rivets on boiler and frame. The running number begins with 38.

Why is the P 8 also called Class 38?

Until 1920 the locomotives belonged to the individual state railways, in this case the Prussian state railway, which assigned its own class designations such as P 8. From 1925 the Deutsche Reichsbahn-Gesellschaft introduced a unified class scheme and placed the P 8 in the range 38.10–40.

How many P 8s were built?

A total of around 3,900 examples were built, starting in 1906 in Germany and later abroad too. That makes the P 8 one of the most-built passenger steam locomotives ever. How many still exist today changes as restorations and society projects progress.

Does Class 38 still run to a regular timetable today?

No. Regular service ended in 1972 with the Deutsche Reichsbahn and in 1974 with the Deutsche Bundesbahn. Preserved locomotives today run exclusively in museum and special service, some operational, some as static exhibits not fit to run.

How fast did the Prussian P 8 run?

Maximum speed was 100 km/h forwards and 50 km/h in reverse. For a passenger locomotive of its era, that was a solid figure – it explains why the locomotives were also used ahead of light express trains.

What does the wheel arrangement 2'C mean?

The figure 2 stands for two trailing/leading axles, and the apostrophe shows they run in a bogie. The letter C stands for three coupled driving axles. So letters count powered axles, figures count free-running ones – a system that works for any European steam locomotive.

Why was the P 8 so successful?

It was simply built, robust, and economical thanks to superheated-steam technology. That made it equally useful for everyday duty on main and branch lines alike. After the First World War, many examples also went to foreign railways as reparations, which further increased its spread.

Where can I see a Class 38 today?

In railway museums and at heritage railways, occasionally hauling special trains. Fixed locations and dates change because locomotives get sold, overhauled or withdrawn for inspection deadlines. So always check the current situation with the relevant operator or via community sightings.
