The locomotives No. 1 and 2 of the Kleinbahn Klockow – Pasewalk were built in 1908 by Orenstein & Koppel . The triple-coupled narrow-gauge tank locomotives were in use on the Kleinbahn route throughout their service life up to 1963. The locomotives were given the road numbers 99 4612 and 99 4613 by the Deutsche Reichsbahn in 1949 .
history
With the commissioning of the line between Klockow and Pasewalk, Orenstein & Koppel's Kleinbahn acquired two triple-coupled wet steam tank locomotives. When the Deutsche Reichsbahn took over management of the Kleinbahn on April 1, 1949, the locomotives were given the road numbers 99 4612 and 99 4613. In the years that followed, the two machines were the only traction vehicles on the route. In the course of 1963 the inspection deadline for the locomotives expired. So it was finally the 99 4501 that carried the last train between Klockow and Pasewalk on October 4, 1963. 99 4612 was retired on December 6, 1966 and 99 4613 on June 18, 1966. One of the locomotives was used as a heating locomotive for a while.
Constructive features
The locomotives had a sheet metal inner frame. The front and rear buffer beams were used for transverse stiffening.
The boiler was fed by two steam jet pumps. The kettle was two-shot. The round steam dome sat on the front part of the boiler and had two pop safety valves. The control linkage to the valve regulator in the steam dome was guided freely above the boiler. The boiler feed valves were located in the front part of the long boiler. The angular sandpit sat behind the steam dome.
The horizontally lying two-cylinder wet steam engine with flat slides worked on the third wheel set and had an Allan trick control.
The conical chimney had a two-part spark arrester. The two front wheel sets were sanded by hand.
The steam whistle was on the cab roof. The Latowski steam flare was originally attached to the chimney. It was later moved to the standing boiler to make room for the turbo generator for the electrical lighting.
The locomotive had a handbrake. The water boxes reached on both sides of the long boiler up to the level of the steam dome. The coal supply was placed on the water boxes.
