There are former Yugoslav diesel-electric class 661 locomotives built by General Motors, former NSB Di 3 locomotives ("NOHABs") imported from Norway (also a construction by General Motors, but build in Sweden by the NoHAB works), and a single Vossloh G1700-2 BB.
The initial locomotives (originally designated RENFE 1900) were single cab hood unit designs, built at General Motor's La Grange, Illinois factory, as an Iberian gauge variant of the EMD G16 locomotive type, using EMD 567 engines; the construction order was completed under license at the MACOSA factory in Spain, using the same components in a double cab design.
