As one of four classes in the German Federal Railway product range for standard electric locomotives, the E 40 was also developed as a locomotive for pulling freight trains on flat terrain. For gradients, 31 locomotives were delivered with resistance brakes independent of the contact wire and designated as substructure class E 40.11. This multi-purpose locomotive was used on the Höllentalbahn railway, among others. From 1968, the class designation of these locomotives was changed to 139 (ex E 40.11) in line with computer technology. To this day, a few of these locomotives are still in service with private railway companies.
