BZA Munich, Kraus-Maffei and SSW developed class E 40, which largely corresponds to the E 10.1 in terms of its technical design, for hauling heavy freight trains on main lines in the lowlands. Only the gear ratio was changed and an electric brake was not fitted as standard. Over 800 of the 110 km/h machines were put into service from 1957. Their power output was 3,260 kW. In 1968, it was redesignated class 140. For a long time, it carried the main load of freight trains on electrified lines, but was also used to pull passenger trains. It was decommissioned at the end of 2016 after almost 60 years of service with DB.
