The BLEAG 5 to 8 were four-axle Mallet locomotives for the meter-gauge Albtalbahn .
history
The Badische local railways (BLEAG) represent the Albtalbahn Karlsruhe to Herrenalb together with branch route Brötzingen and Ettlinger side panel , procured 1897/1898 at the Society Mechanical Engineering Karlsruhe three steam locomotives to the system Mallet with the operation numbers 5 kb to 7 kb . In 1900 a fourth locomotive with the number 8 kk was added. The superscript letters kk stood for Malletlok, 1000 millimeter gauge .
The locomotives were intended for traffic south of Ettlingen , as only box locomotives were permitted in the city of Karlsruhe .
After the electrification of the route from Ettlingen to Herrenalb and Brötzingen in 1911, they were used in freight traffic and for heavy trains in rush hour traffic. Locomotive 6 came to the Heeresfeldbahn in France in 1915 and did not return after the war. From 1932 the other locomotives were numbered 5 s , 7 s and 8 s , from then on the s stood for narrow gauge.
Locomotive 8 was retired in 1956. From 1957 to 1961 the route from Karlsruhe to Bad Herrenalb was re-gauged to 1,435 millimeters. Until 1966, locomotives 5 and 7 were kept for the Busenbach – Ittersbach line, which was later re-tracked, and then decommissioned.
Locomotive 7 was set up on a playground in Karlsruhe's Rappenwört lido in 1966. In 1995 it was acquired by the German Railway Association (DEV) from the Albtal-Verkehrs-Gesellschaft and brought to Bruchhausen-Vilsen . Since then, the refurbishment has been carried out in small steps, since the maintenance of the operational locomotives at DEV is in the foreground.
technical features
The locomotive has two drive axles in the main frame and two more in a bogie. The frame is designed as an inner frame. The long boiler has three boiler sections. The water was supplied through Friedmann injectors. The locomotives have two-stage steam expansion, the fresh steam is first used in the rear cylinders and then in the front cylinders on the bogie. The locomotives have an external Heusinger control with flat slide. On top of the boiler was a steam dome and at first only a sand dome at the rear, later a second sand dome was retrofitted for the front pair of axles. As a brake was Riggenbach - counter-pressure brake and a Hardy vacuum brake available. The counter pressure brake was removed before 1930. A compressed air brake was retrofitted for the trolley operation .
