The 3 was delivered as an 0-6-2T in 1899 (Locobase 12578) along with two sisters. Decades later, according to Wikipedia, the 3 was rebuilt by East Germany's DDR at their Gorlitz Works as an 0-6-0T on a new frame with a new boiler, axles, and cab.
Retired on 5 November 1976, the 3 was immediately placed in museum service at the Holiday Park in Hassloch. It moved to IG Pre+nitztalbahn in Jÿhstadt in 1998.
