The vehicles of the Grand Ducal Oldenburg State Railways of the class P 4.1 were passenger locomotives with the 2'B wheel arrangement. After the takeover by the Deutsche Reichsbahn, the locomotives were classified in the 36.12 series.
history
After the locomotives of the class P 3.2 were no longer sufficient for operation, the Oldenburg State Railways procured vehicles with the wheel arrangement 2'B based on the model of Prussian locomotives from 1896 to 1902. The locomotives were given the track numbers 107–111, 116, 129–134, 139–144, 150 and were named after birds. The locomotives were used in passenger and express train service on the Oldenburg main lines. With a pulling power of 368 tons at 68 km / h, the power was sufficient for the flat stretches. After the takeover of all locomotives by the Deutsche Reichsbahn, they were re-designated as 36 1201 to 36 1219 and retired by 1931.
Constructive features
The locomotives had a sheet metal frame with a thickness of 25 mm. The riveted long shell consisted of three shots. The rear boiler with a copper fire box was drawn in between the frame sheets. The safety valve was of the Ramsbottom type. Compared to the Prussian model, the boiler was almost a meter shorter, and the steam dome was dispensed with and the steam collecting pipe was placed in the long boiler. The regulator was located in the smoke chamber. Due to the smaller boiler, a smaller grate area was sufficient.
The frame was supported at four points. The two coupled wheel sets were firmly mounted in the frame, and the springs were connected to one another by means of compensating levers.
The horizontally arranged two-cylinder wet steam engine worked on the first coupled axle. The Heusinger control was on the outside. The simple flat slide valves originally used were replaced by relieved flat slide valves.
The Westinghouse air brake worked on both coupling axles. The sand spreader sanded the first coupled wheel set from the front. The gas lighting was of the Pinsch type. The locomotives also had a steam heating system. They were coupled to a 3 T 12 tender.
