Electric locomotive series 1043 of the Austrian Federal Railways. To meet the ÖBB's request for a quick delivery of new locomotives for freight transport on the Tauernbahn, four locomotives were diverted from a series of the Swedish type Rc 2 that was under construction. The locomotives equipped with thyristor technology performed well, and a total of ten machines were delivered by 1974. Hardly any other series of the ÖBB had such a wide variety of labeling variants throughout its operational period.
