Roco 70434 H0 E-Loc 104401 of Swiss Federal Railways
At the beginning of the 1970er, the Austrian locomotive industry had constantly increasing performance requirements to develop a completely new high-performance electric motor vehicle in thyristor technology. SGP, responsible for the mechanical part, and BBC (now ABB), Elin and Siemens for electrical equipment, handed over two prototype machines (1044.01 in December 1974 and 1044.02 in February 1975) to Austrian Federal Railways for testing in the mid-1970er on their own account. These universally applicable marginal power locomotives with an output of 5,280 kW and a maximum permissible speed of 160 km/h were able to convince in essence during their testing on the South Railway and the West Railway, between Vienna and Salzburg. In April of 1976, a first series order was already placed.This text is machine translated.
