The E 93 was developed to be able to increase the train weights on the Geislinger Steige to 1,200 tonnes. Like the E 44 it had nose-suspended motors but was designed as a crocodile with the main machinery room and driver's cabs on a bridge frame and large hoods mounted on the bogies. It formed the basis for the more well-known E 94. The use in regular service on the Bundesbahn ended in 1976 and the last locomotives were used as helper locomotives until 1984, still on the Geislinger Steige.
