The Baureihe E 40 is a German Standard electric locomotive (German: ''Einheits-Elektrolokomotive'') commissioned by the Deutsche Bundesbahn in 1955, designed for freight trains. Since the 1968 renumbering, it is listed as Class 140 and Class 139. ==Development== In 1950, the Deutsche Bundesbahn introduced two general types of electric locomotives with standardised components: A twelve-wheel (UIC: Co'Co') freight train locomotive as successor for the class E 94 and an eight-wheel (UIC: Bo'Bo') general purpose electric locomotive as successor for the class E 44. A new feature was that the driver was seated, whereas formerly they had to stand. During the construction period the speed requirement for a general purpose locomotive (working title E 46, then changed to class E 10) was increased to that point that the layout was one for an express train locomotive. Two types were not found sufficient to cover all needs, so the Einheits-Elektrolokomotiven program was changed to four general types: Light passenger train locomotive (class E 41), express train locomotive (class E 10), freight train locomotive class E 40 and heavy freight train locomotive (class E 50). All four classes were designed to share as many components as possible.
