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".

Production

Deutsche Bundesbahn E 194 in 1985

146 units were built until the end of the Second World War, as it was considered important for the war effort. They were classified as KEL 2 during that time period.

After World War II, a further 49 units were ordered by the Deutsche Bundesbahn and delivered as late as 1957. The final 23 units had their power rating increased to 4,680 kW (6,280 hp). From 1968, the top speed of these locomotives was raised to 100 km/h (62 mph), and were reclassified as E 94.2, later Class 194.5, due to several technical differences.

Transfers to ÖBB and DR

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.

Deutsche Reichsbahn refurbished 23 of the E 94 locomotives they retrieved from the Soviet occupation zone, and were put to work on heavy freight trains and occasionally express trains.
