To meet the ÖBB's desire for a quick delivery of new locomotives for freight transport on the Tauern Railway, 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 diverse range of lettering variations during its service life. The 1043 002, one of the locomotives in the "ÖBB-Jaffa-Design," was in service in the 1990s with an umber-gray roof, frame, and chassis. The upper decorative stripe was placed above the front windows. The locomotive plates were removed, and the locomotive numbers were applied as adhesive digits on the frame.
