Prussian P 6
class of 275 German 2-6-0 locomotive
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 and the unusual position of the boiler. As a result, and in spite of the relatively small, 1,600 mm (62.99 in) diameter, driving wheels (on the prototype they were only 1,500 mm or 59.06 in), the locomotives were authorised to travel at up to 90 km/h (56 mph), 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: 44 to Poland (PKP Oi1), 24 to Belgium, 19 to France (16 to the Nord (3.1551–3.1566), 3 to Alsace-Lorraine), 9 to Italy (FS 626), 6 to Lithuania, 4 to Latvia and 4 to the Territory of the Saar Basin (2101–2104). 163 locomotives were taken over by the Deutsche Reichsbahn as DRG Class 37.0-1, where they were allocated the running numbers 37 001 to 37 163. In 1935 the four Saar locomotives were incorporated into the DRG fleet as 37 164 to 37 167.

Why this record matters
The phrase “class of 275 German 2-6-0 locomotive” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Sep 6, 2025. The linked authority identifier is Q454903. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1902, 1910, 1551 and 1566.
A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
