History

These engines, nickname the 'prairie horse' (Steppenpferd) were developed specially for the long, flat routes in West and East Prussia. 95 examples were built by the firms of Schichau, Linke-Hofmann and others. The two units with operating numbers 24 069 and 24 070 were supplied by Borsig with a medium pressure boiler. These locos ran with a boiler overpressure of 245.1 N/cm2 (355.5 psi), but were rebuilt in 1952.

The Deutsche Bundesbahn took over 38 locomotives and retired them by 1966. The last one with the DB was locomotive number 24 067, which was stabled in Rheydt and taken out of service there in August 1966. The engines were given operating numbers 24 001 to 24 095.

Engine numbers 24 002, 004, 009, 021 and 030 were left with the DR after the Second World War. They were all stabled in Jerichow shed in 1960 and their sphere of operations until 1968 was the branch line network of the Kleinbahn AG in Genthin. No. 24 009 was re-numbered in 1970 to 37 1009 and was used as a reserve breakdown engine in Güsten and Stendal. In 1972 it was sold to the West German railway magazine Eisenbahn-Kurier.

Thirty-four locomotive remained in Poland after the Second World War, where PKP classified them as Oi2. They served until the last one was withdrawn in 1976. One of the preserved locomotives in Germany, no. 24 083, had been in service in Poland.

The locomotives were equipped with 3 T 16 and 3 T 17 tenders.

Four Class 24 locomotives have been preserved: three in Germany (24 004, 24 009 and 24 083), and one in Poland (Oi2-29).

gollark: I can actually do a bit of code sharing between the client and server code which is neat.
gollark: Although I think it would be in python too because... python bad?
gollark: You see, in JS even something like "using an undefined variable" is a *runtime* ReferenceError.
gollark: I actually use TypeScript without even... writing types... the majority of the time, because it means I actually get working autocomplete, and my IÐE will detect errors which for some insane reason JS only notices at runtime.
gollark: TS has compilation anyway, it basically just involves removing the type annotations (this is actually separate from the typechecking).
