The narrow-gauge tank locomotives No. 6 to No. 10 of the small railways of the Jerichow I (KJI) district were supplied by the Christian Hagans machine works between 1902 and 1910 . In 1949, two locomotives were added to the Deutsche Reichsbahn with the road numbers 99 4614 and 99 4615. None of the locomotives have survived.
history
From 1902 the small railways of the district Jerichow I procured a second series of triple- coupled tank locomotives . The Hagans machine works supplied three locomotives in 1902. Another machine followed in 1909 and 1910.
Locomotives 6 to 8 were retired between 1926 and 1939. Nos. 9 and 10 were given road numbers 99 4614 and 99 4615 after the Deutsche Reichsbahn took over the circular railways.
The locomotive 99 4614 was parked and taken out of service in 1963 due to the closure of its main line Loburg - Gommern . It was scrapped in 1966. The 99 4615 was retired in 1951.
Constructive features
The locomotives had an outer frame. The wheel sets were cushioned by overhead leaf spring packages. The springs of the two rear wheel sets were connected by a compensating lever .
The large steam dome sat right in front on the long boiler, directly behind the chimney. The flat slide control was housed in the cathedral. The two boiler feed valves were also located at the front end of the boiler, and they were fed by two steam jet pumps. The angular sandpit was arranged between the driver's cab and the steam dome. The Ramsbottom safety valves were right in front of the cab . The original Prüssmann chimney was later replaced by a slightly conical sheet metal chimney.
The horizontally arranged two-cylinder wet steam engine worked on the third wheel set and had a Stephenson control with flat slide. The wheel sets had Hall cranks.
The front and rear wheel sets were sanded by hand. The steam whistle and steam flute mechanism were housed on the driver's cab roof.
The water boxes reached on both sides of the long boiler up to the height of the steam dome. The coal supplies were stored on the left water tank.
The Deutsche Reichsbahn retrofitted a turbo generator for the electrical lighting. A throw lever handbrake served as the brake.
