Construction

Because Garbe was an advocate of the simplest possible designs, a straightforward, superheated steam

, two-cylinder driving gear was envisaged. The P 8 benefited especially from superheated steam technology, which had just been developed by Wilhelm Schmidt

 (nicknamed 'hot steam Schmidt'), that led to outstanding performance for those times. The P 8 was a very economical locomotive that did not make great demands on the ability of the engine driver. At the outset Garbe even designed the P 8 as an express train

 locomotive, with the expectation of attaining a top speed of 110 km/h (68.4 mph). As a result the first units were fitted with low wind-resistance, tapered driver's cabs.

The enthusiasm of crews for the new locomotive was at first muted. The boiler

 at the front end of the firebox), however against that there were numerous teething troubles, e.g. the driving rod bearings were too small, which continually led to overheating, and the loosely coupled Prussian box tender, which led to disturbing riding qualities when running tender-first. Its riding performance was never fully satisfactory. As a result of poor weight compensation the top speed estimated by Garbe was never achieved and it was eventually assessed at 110 km/h.

One characteristic feature of the P 8 is the large distance between the centre and rear coupled axles. At the outset the P 8 only had a steam dome

; later a forward feed dome was added. Further constructional changes affected, inter alia, the driver's cab roofs, the smoke deflectors

Smoke deflectors are vertical plates attached to the front of a steam locomotive on each side of the smokebox. They are designed to lift smoke away from the locomotive at speed so that the driver has better visibility unimpaired by drifting smoke....

 and various external assemblies.

There would appear to be been a number of boiler variations. The following combinations can be seen in photographs:

1/. boiler feeds on sides on boiler, steam dome in front of sandbox
2/. boiler feeds on sides of boiler, steam dome behind sandbox
3/. boiler feeds on top of boiler without feed dome, steam dome behind sandbox
4/. boiler feeds on top of boiler with feed dome, steam dome behind sandbox

At least some of very early engines (those with the "V" cabs) carried type (1) boilers and this type appears to have been the standard in the early years. Types (3) and (4) do not seem to have appeared until after WWI but ultimately became prevalent. See "100 Jahre Preussische P8" (Eisenbahn Kurier).

In order to be able to turn the locomotive even on small turntables, the Prussian state railways fitted the P 8 with tenders that originally held 21.5 m³ of water and 7 t of coal. Later the Deutsche Bundesbahn coupled the Class 38 with the tenders of withdrawn wartime locomotives the so-called 'Kriegslokomotive

n', especially the bathtub tenders (Wannentender), which could carry more fuel. In addition the top speed when running tender-first was increased from 50 km/h (31.1 mph) to 85 km/h (52.8 mph).

On the other hand, the Deutsche Reichsbahn also used tenders of DRG Class 17 steam locomotives that had been taken out of service. These were the so-called long-distance tenders.

Employment

The P 8 could haul 300 t at 100 km/h (62.1 mph) and 400 t at 90 km/h (55.9 mph) on the flat and, after the world wars, could be found in almost the whole of Europe. The order to build the first 10 machines was issued to the firm of Schwartzkopff (later the Berliner Maschinenbau

 with the designation "Coeln 2401".

The P 8 could be used for a variety of duties and was found in heavy express train and goods train services heading almost every train. Even the railway authorities were very pleased with these engines, because the last P 8 locomotives were not mustered out by the Deutsche Reichsbahn until 1972, and by Deutsche Bundesbahn
