Three different types of German electric goods train locomotive belonged to the Deutsche Reichsbahn's DRG Class E 91.

The front and rear sections each had a driver's cab and an engine room and were fixed to the bogies.

The gangways between the individual sections of the engine room were protected by bellows; there were no dividing walls.

The Bavarian locomotives could be easily told from their Silesian counterparts by the additional front door between the two cab windows (see photograph, right, of the Bavarian E 91 11, parked up in AW Frankfurt as a stationary transformer for the test shop.

In the DRG, the south German engines remained permanently in Bavaria at Munich main station, Regensburg, Rosenheim and Freilassing locomotive depots.

A new lease of life on the Rübeland Railway did not come to fruition, because it soon became apparent that this line would be electrified for 25 kV, 50 Hz.

After further retirements, 17 locomotives remained in the DB fleet in 1950 (numbers E 91 01 - 03, 07 - 11, 13, 15, 16, 18, 20, 81, 88, 89 and 94) and they were modernised between 1958 and 1960, all the electrical equipment being renewed.

In their final years the engines were not only deployed in south German locomotive depots, but also at Oberhausen in the Ruhrgebiet.

The locomotives were to be equipped with an electric brake for hauling heavy trains on long inclines.

Locomotive E 91 96 was retired as early as 1943 after an accident, but not dismantled in southern Germany until after the war.

Number E 91 104 found itself in the Dessau repair shop (Reichsbahnausbesserungswerk or RAW) with bomb damage.
