The class P 3 1 of the Prussian State Railways were steam locomotives with the wheel arrangement 1B for express and passenger train traffic. The locomotives were also procured from the Mecklenburg Friedrich-Franz Railway and various private railways.
history
On the basis of the construction of the Prussian P 2 and the experience gained with it, new sample sheets were drawn up in 1883 by the Standard Parts Commission. In particular, the boiler output should be increased in order to be able to provide the necessary transport services. With the previous locomotives it was necessary on certain routes that the passenger trains had to be driven in double traction. This goal was achieved through a higher boiler pressure, a larger grate area and smaller cylinders. In addition, the steam engine was better matched to the boiler.
The locomotives procured from 1884 according to sample sheet III1 were primarily intended as train locomotives for express and passenger trains on main lines. The Prussian railways procured 597 locomotives from 1884 to 1897. With the reorganization of the numbering system from 1905, the locomotives were classified in the number group 1601 to 1700. The Hessian Ludwigsbahn procured 20 locomotives of this type from Henschel and Hanomag from 1890 to 1895, but these differed in some dimensions from the Prussian locomotives. These locomotives were given the track numbers 9, 12, 17, 18, 125, 194–201 and 207–213. All machines were taken over by the Prussian state railways. Of the two locomotives procured in 1895 by the Royal Prussian Military Railway , one was taken over by the State Railways. The Holstein Marschbahn had nine locomotives , the Main-Neckar Railway six and the Dortmund-Gronau-Enscheder Railway seven locomotives. All was taken over by the Prussian State Railways. Of the Prussian locomotives, the provisional re-drawing plan from 1923 provided 12 locomotives to be re-designated as train numbers 34 7001 to 7012. All locomotives were retired by 1925. In 1894/1896, the Lübeck-Büchener Railway procured three locomotives from Berliner Maschinenbau AG. They were given road numbers 47, 48 and 51 (from 1917: 23 "to 25"). The machines were taken out of service shortly afterwards.
13 machines came to the PKP in Poland as a result of the First World War in 1918. There they were given the type designation Oc1. All 13 were taken out of service there by 1939 at the latest.
The Mecklenburgische Friedrich-Franz-Eisenbahn acquired 39 locomotives from 1888 to 1907 and classified them in class VI. The German-Nordic Lloyd acquired two locomotives with the lane numbers 8 and 9, 1895, these locomotives were given the track numbers 101 to 141. employed were the locomotives among other things, the express train service on the route between Neustrelitz and Warnemünde. Of these locomotives, 22 were redrawn by the Deutsche Reichsbahn in 1925. They were given the numbers 34 7301 to 7308 (12 t axle load) and 34 7351 to 7364 (13 t axle load). In the end, the locomotives were only to be found in shunting service.
The machines were able to move a passenger train with 185 t on the plain at 80 km / h. With a gradient of 1: 100, a 250 t train could be transported at 24 km / h.
Constructive features
The locomotives had a sheet metal inner frame. The Crampton kettle had a steeply sloping grate surface. The steam dome sat on the rear boiler section. The boiler feed valves were located in the middle of the boiler of the first boiler section. In the 1890s, the locomotives were fitted with a longer smoke chamber .
The two-cylinder wet steam engine was arranged horizontally in front of the wheelset. It worked on the first coupled axle. The Allan controls were internal.
The drive was supported at four points. The wheelset was firmly mounted in the frame and had overhead leaf springs. The coupled wheel sets were cushioned below the axles by leaf springs. The springs of the wheel set and the front coupled wheel set were connected by an angle lever.
The locomotives had Carpenter- type air brakes for the tender and the wagons. Some of the locomotives were also equipped with a Westinghouse air brake. The locomotives delivered from the 1890s onwards had a quick drag brake that acted on the two coupling wheels from both sides. The sand spreader sanded the front coupling axle from the front. The sandpit was square.
The locomotives were coupled with tenders of the Prussian type 3 T 10.5 or 3 T 12 with a fuel supply of 4 tons of coal.
