As a generic IM designated Royal Saxon State Railways narrow gauge - steam locomotives of the type Fairlie , specifically for the meter gauge dolly track had been built (Reichenbach Oberheinsdorf). The Deutsche Reichsbahn classified the locomotives in the 99.16 series from 1925 .
history
For the Rollbockbahn near Reichenbach in Vogtland , the Sächsische Maschinenfabrik in Chemnitz supplied three Fairlie locomotives with the serial numbers 2647 to 2649 in 1902. The Kgl. Saxon State Railways gave the vehicles the numbers 251 to 253.
The number 253 (later 99 163) was in use from August 14, 1916 to May 1917 on the Klingenthal – Sachsenberg-Georgenthal narrow-gauge railway , where it was initially only supposed to carry out test drives. It was then also used there in front of scheduled freight trains until the railway's electrical systems were completed. In 1925 the three locomotives were given the numbers 99 161 to 99 163 from the Deutsche Reichsbahn. From April 1, 1939 to April 4, 1941, the locomotive 99 162 ran on the Mosbach – Mudau narrow-gauge railway in Baden . The 99 163 was confiscated for military service during World War II . In 1942 the machine was transported by ship via Greece to the Crimean peninsula , where it never arrived. The ship was sunk in the Black Sea by a torpedo hit .
The locomotives 99 161 and 99 162 were retired in 1963 (last day of operation was September 14, 1962 after an accident). The 99 161 was scrapped in 1963, but the 99 162 was brought to Klingenthal in March 1964 at the instigation of the Klingenthal district monument conservationist and placed under monument protection. As a technical monument at the Klingenthal train station, it was intended to commemorate the 1916/1917 loan use of the IM 253 on the Klingenthal narrow-gauge railway. In 1967, however, the Klingenthal city council decided against the project. The locomotive was then transported to Raw Görlitz-Schlauroth on July 25, 1968, where it was refurbished as a museum in 1970/1971 and returned to its original condition.
In 1971 it took over the Dresden Transport Museum as a non-operational museum locomotive. It was presented to the public for the first time at the MOROP Congress in Dresden in September 1971. In 1974 it was exhibited again at the Leipzig spring fair.
In the absence of suitable exhibition space, it was then placed behind for more than two decades in the Ilfeld locomotive shed on the Harzquerbahn . It was not until 1999 that it returned to its old home in Reichenbach, where it was given to the traditional Rollbockbahn eV association on October 30, 1999 as a permanent loan . Today the museum locomotive is in the museum station in Oberheinsdorf , which was built near the former end point of its main line.
technical features
The vehicles had a boiler with two separate fire boxes in the standing boiler . The flue gases flowed from the fire boxes through the heating pipes of the respective long boiler to the two smoke chambers at the ends of the boiler, from where they were released through the chimneys. The driver's cab enclosed the boiler in the middle. This separated the workplaces for the engine driver and the stoker. Originally the entire locomotive was roofed over, this roofing was removed in the 1920s and reassembled during the restoration of locomotive 252 to the museum locomotive 1970/71 in Raw Görlitz-Schlauroth.
In the two steam domes on the two long boilers there is a steam regulator through which the steam was directed to the bogie below. The controls could be operated from both ends of the locomotive and from the driver's cab. They are permanently connected with a rod.
Next to the two long boilers there are four storage tanks for the boiler water. In the tanks on the heater side there is also the coal supply in a separate area.
The locomotive has a lever brake to brake the train . However, this does not affect the locomotive itself. The locomotive can be braked with a vapor brake , which the driver operates, or with a throw lever brake , the lever of which is located near the stoker. The throw lever brake only acts on the two axles in the rear bogie, while the vapor barrier only acts on the two axles in the front bogie. Later the locomotives were also equipped with an air brake. The air pump required for this was placed in the front right next to the smoke chamber and the associated air tanks were attached to the circulation next to the water tank. This equipment was removed from the museum locomotive.
The engines of the locomotives were, because of the roads planum laid track body, as with steam tramway locomotives usual, fully dressed. This served to protect the engine on the one hand and passers-by on the other.
