The DRG Class E94 is an electric heavy freight locomotive built for Deutsche Reichsbahn from 1940, with the bulk of deliveries taking place in that year. It was a major evolution of the DRG Class E 93. Railway aficionados still call the type "Grünes Krokodil" (Green Crocodile) because of the resemblance to the Swiss locomotive nicknamed "Crocodile".
After World War II, new units were ordered and delivered as late as 1957.
After the war, 44 units were placed under the authority of the Austrian Federal Railways (ÖBB). In 1952, the ÖBB ordered three complementary locos. In 1954, they were classified as class 1020.
