Prussian P 6
Encyclopedia
The Prussian Class P 6s were passenger locomotives operated by the Prussian state railways
with a leading axle and three coupled axles.
The P 6 was conceived as a so-called universal locomotive. The first vehicle was manufactured in 1902 at Düsseldorf
by the firm of Hohenzollern
. This engine has a number of features that are characteristic of its designer, Robert Garbe
: a narrow chimney located well forward, the unusual position of the boiler
and, not least, insufficient weight balancing. As a result, and in spite of the relatively small, 1,600 mm diameter, driving wheels (on the prototype they were only 1,500 mm), the locomotives were authorised to travel at up to 90 km/h, a speed which could not be attained in practice due to its poor riding qualities.
The smokebox
superheater installed on the first machines was soon replaced by a smoke tube superheater
. In all, 275 engines of this class were built up to 1910. 110 examples had to be handed over after the First World War as reparations
. 163 locomotives were taken over by the Deutsche Reichsbahn
as DRG Class 37.0-1, where they were allocated the running numbers 37 001–163. The locomotives with numbers 37 201–206 were, by contrast, G 6 and P 6 class engines respectively of Lübeck-Büchen Railway (LBE), that had a different design from the Prussian locomotives.
The Prussian P 6s were retired by about 1950. The few engines left after the Second World War were no longer employed by the Deutsche Bundesbahn
and the Reichsbahn.
The locomotives taken over by the Polish State Railways
(PKP) were given the designation Oi1.
One of them has been preserved and can be viewed in the Warsaw Railway Museum
.
The engines were equipped with Prussian tenders of class pr 2'2' T 16.

The smokebox
Smokebox
A smokebox is one of the major basic parts of a Steam locomotive exhaust system. Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler. The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney .To assist...
