The locomotives No. 21 and 22 in the third occupation were narrow -gauge locomotives that were taken over by the Mecklenburg-Pomerania narrow-gauge railway in 1945 . In 1949 the locomotives were classified by the Deutsche Reichsbahn in the class 99.365 .
history
After the end of the Second World War and the subsequent reparations payments to the Soviet Union , only seven locomotives out of more than 20 remained on the Mecklenburg-Pomerania narrow-gauge railway network.
The company therefore took over two construction locomotives found in Woldegk . Although the locomotives came from different manufacturers, they were largely identical.
A locomotive was designated as number 21, which Jung delivered in 1941 with the factory number 9296 to the construction company Erich Brangsch in Leipzig-Engelsdorf. The locomotive with the number 22 was built in 1940 with the factory number 15793 by Krauss-Maffei for E. Kirchhoff in Munich.
The reconditioning of the locomotives took several years. Number 21 was put back into service in 1947 and number 22 in 1949. After the MPSB was taken over by the Deutsche Reichsbahn in 1949, the 21 was given the new road number 99 3652 and the 22 the 99 3651.
Since the locomotives could not be used in the route service, the 99 3652 was rented to the Anklam sugar factory . In 1958, both locomotives were sold to VEB Kieswerke Doberlug-Kirchhain .
Constructive features
The locomotives had an inner frame. The steam dome was behind the chimney and had two safety valves. On 99 3652, the regulator bushing was located directly on the steam dome. From this, the inlet pipes on the outside of the boiler led to the cylinders.
The two-cylinder wet steam engine with Heusinger control was slightly inclined and worked on the rear wheel set. The cylinders had flat slide valves.
The sandpit sat behind the steam dome on the boiler and sanded both sets of wheels from the outside. The locomotives had a handbrake and a steam whistle on the cab front wall.
