Mecklenburg P 3.1
The genus P 31 of the Prussian state railways were steam locomotives with the wheel arrangement 1B for quick and passenger trains. The locomotives were procured from the Mecklenburg Friedrich- Franz Railway and various private railways.
History
On the basis of the design of the Prussian P 2 and the experience gained to date in 1883 new pattern sheets were prepared by the Standards Commission. In particular, the boiler capacity should be increased in order to provide the necessary transport can. So it was necessary with the previous locomotives on certain routes that passenger trains had to be run 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 suited to the boiler.
The 1884 procured according to the pattern sheet III1 locomotives were designed primarily as a motive power of high-speed and passenger trains on main lines. The Prussian railways procured 1884-1897 597 locomotives. The locomotives were filed with the reorganization of the numbering system from 1905 in the number group from 1601 to 1700. The Hessian Ludwig Railway procured from 1890 to 1895 20 locomotives of this type of Henschel and Hanomag, but differed in several dimensions of 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 1895 acquired by the Royal Prussian military railway locomotives were taken over one of the state railway. The Holstein Marschbahn had nine, the Main-Neckar Railway six and the Dortmund -Gronau - Enschede railway seven locomotives. All was taken over by the Prussian State Railways. Of the Prussian locomotives 12 locomotives for renumbering in the train numbers were provided 34 7001-7012 in the provisional renumbering of 1923 yet. By 1925, all locomotives were retired. The Lübeck- Büchener Railway procured 1894/1896 three locomotives of the Berliner Maschinenbau AG. They were given the operating numbers 47, 48 and 51 ( 1917: 23'' to 25 ''). The machines were retired shortly thereafter.
13 machines came as a result of the First World War in 1918 to PKP after Poland. They got there, the type designation Oc1. All 13 were taken out of there until at least 1939.
The Mecklenburg Friedrich- Franz Railway acquired from 1888 to 1907 39 locomotives and strung them into the genus VI. The German - Nordic Lloyd acquired two locomotives with the track numbers 8 and 9 in 1895 received these locomotives railway locomotives were the numbers 101 to 141 Used inter alia in express train services on the route between Neustrelitz and Warnemünde. Of these locomotives were re-drawn in 1925 by the German Reichsbahn still 22. They were given the numbers 34 7301-7308 ( 12 t axle load ) and 34 7351-7364 ( 13 t axle load ). The locomotives were last only be found in the shunting.
The machines were able to carry a passenger train with 185 t in the plane at 80 km / hr. With a slope of 1:100, a 250 -tonne train with 24 km / h could be transported.
Design features
The locomotives possessed a sheet metal inner frame. The Crampton - boiler had a steeply sloping grate area. The steam dome sat on the rear boiler shot. The boiler feed valves were located on the middle of the first boiler boiler shot. In the 1890s, the locomotives were fitted with a longer smoke chamber.
The two-cylinder wet steam engine was placed horizontally in front of the wheel set. It worked on the first coupled axle. The Allan valve was inside.
The drive was not supported at four points. The wheelset was fixed in the frame and had overhead leaf springs. The Kuppelradsätze were mitigated below the axles by leaf springs. The feathers of the wheel set and the front Kuppelradsatzes were connected by a bell crank.
The locomotives possessed compressed air braking devices of the type Carpenter for the tender and the car. Some of the locomotives were also equipped with a Westinghouse air brake system. The delivered from the 1890s locomotives had a grinder quick brake that worked on the two coupling wheels from both sides. The gritters sanded the front coupled axle from the front. The sandbox was square.
Coupled were the locomotives with tenders of the Prussian type 3 T 3 T 10.5 or 12 with a fuel reserve of 4 tons of coal.
