The D IV was a locomotive of the Bavarian Eastern Railway .
description
The vehicles with an inner frame and all-control system were delivered in three series, which differed in terms of dimensions. The original designation D was changed to D IV after the Ostbahn was taken over by the Royal Bavarian State Railways. Originally, all vehicles were to be taken over by the Deutsche Reichsbahn . However, only six copies that received the numbers 88 7021-7026 were redrawn. By the end of the 1920s, they were all retired or sold.
