The locomotives No. 1 to 7 (2nd occupation) of the Mecklenburg-Pomerania Schmalspurbahn AG were manufactured from 1906 to 1913 by the Arnold Jung Lokomotivfabrik . Three locomotives were taken over by the Deutsche Reichsbahn on April 1, 1949 and were given the road numbers 99 3351 to 99 3353. These three locomotives are still in existence today.
history
In 1906, the MPSB purchased two C1 'n2t locomotives for the first time. The machines were given road numbers 1 and 2 in a second occupation. They were also given the names JAKOBI and REUSS . 1907 followed with the BARON VON TROSCHKE and the KAYSER the locomotives with the road numbers 3 II and 4 II . GRAF SCHWERIN LÖWITZ (5 II ) followed in 1908, KATTER (6 II ) in 1911 and RAT VOSS (7 II ) in 1913 . To extend the range, the locomotives were equipped with two-axle water tenders manufactured by MPSB itself. This could also carry coal if necessary. The locomotives were rebuilt and adapted in the course of operation, especially in the area of the chimney and the driver's cab.
After the end of the Second World War, locomotives 2, 3, 6 and 7 had to be given to the Soviet Union as reparations . In 1949 the Mecklenburg-Pomerania narrow-gauge railway was taken over by the Deutsche Reichsbahn. According to the numbering scheme, locomotives 1, 4 and 5 were assigned to the 99.335 series. The machines were in use until the MPSB ceased operations in September 1969.
The 99 3351 was sold to a dealer in Lauenburg / Elbe in 1970 . In 1973 the locomotive came to the Georg Mohun Outdoor Steam Museum near San Francisco. From 1985 she was owned by the La Porte Country Historial Society near Chicago and from 1995 on the Edaville Railroad , South Carver. In 1998, the Frankfurt Feldbahnmuseum acquired the locomotive. The completely restored locomotive has been used for museum trips since 2006.
The 99 3352 was refurbished until 1973 and exhibited as a memorial in Friedland together with some passenger cars. In 1994 the locomotive was moved to an exhibition hall at the former station.
The 99 3353 was acquired by the Llanberis Lake Railway in Wales in 1972 . The locomotive has been in service on the Brecon Mountain Railway since 1977 .
Constructive features
The vehicles had an outer frame and a trailing axle in the Bissel frame . The wheelsets with a running circle diameter of 630 mm had a center distance of 700 mm. The drive took place on the third axis.
The two-cylinder wet steam engine was slightly inclined and had a Heusinger control.
The steam dome was behind the chimney and had two safety valves. The round sandpit was also sitting on the boiler and manually operated the third set of wheels from the front. The two jet pumps fed the boiler at the height of the steam dome.
The locomotives themselves carried 0.6 m³ of water and 0.55 tons of coal each. To increase the range, there was also an auxiliary tender with a larger water supply of approx. 3.0 m³. With some machines a coal box was built behind the driver's cab. In the original version, the locomotives had a Kobel chimney.
The locomotives had a handbrake. On delivery, locomotive No. 6 was equipped with a Körting type suction air brake on a trial basis.
The Deutsche Reichsbahn is retrofitting the locomotives with a turbo generator for electrical lighting.
