Invention and Engineering
The steam locomotives of DR Class 99.77–79 were ordered by the Deutsche Reichsbahn in East Germany after the Second World War. They were narrow gauge locomotives with a 750 mm rail gauge and were built for the narrow gauge lines in Saxony. The locomotives were largely identical to the DRG Class 99.73–76 standard locomotives (Einheitslokomotiven) built in the 1930s. To differentiate them from their predecessors they were described as Neubaulokomotiven or newly designed engines.
