Hybrid and dual mode railway traction - Impact of new technologies

The concept of dual-mode machines, with thermal or electric traction, is an old one. Starting with a diesel-electric engine, which already has electric motors for traction power, it's easy enough to add electric power collection equipment. As early as 1936, Compagnie du Midi commissioned Alsthom (Tarbes) and Soulé (Bagnères-de-Bigorre) to build two "amphibious" railcars, powered by 1,500 V direct current, or by a diesel-electric generator (figure...
