DRG Class E 93

The DRG Class E93 is an electric heavy freight locomotive built by AEG for Deutsche Reichsbahn in 1933. Its development was triggered by the electrification of the Geislinger Steige, a steep grade of the mainline railroad between Stuttgart and Ulm, which had been electrified in 1933 and required powerful new freight locomotives to overcome it with heavy freight trains.
