To meet the ÖBB's request for the rapid 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 displayed such a variety of labeling options throughout 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 affixed as adhesive digits on the frame.
