Class Details by Steve Llanso of Sweat House Media

Class BR 99 4511 (Locobase 6540)

Data from Alfred Gieseler, "Baureihe 99 4511" on his Dampfmaschinen und Lokomotiven website at [link], last accessed 4 November 2020. See also [link], last accessed 14 May 2011.

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.
