The electric locomotives of the 342 series were built in the 1960s by the Italian machine manufacturer Ansaldo for the Yugoslav Railways ( ).

They were designed for use on the Slovenian railway network and are considered a scaled-down version of the 362 . With the independence of Slovenia in 1991, the locomotives were taken over by the Slovenian State Railways .

After the commissioning of more modern series, some vehicles were sold to two Italian railway companies in the 2000s, where they can be used with the identical traction current system: eight came to Ferrovie Nord Milano (FNM) in 2002 , six to Ferrovie Emilia Romagna (FER) in 2005 . Both placed them in group E.640 and used them in front of freight trains on the RFI . The locomotives have now been replaced by more modern locomotives and only serve as a reserve.

ÖBB wants to buy five SŽ class 342 locomotives for its subsidiary Rail Cargo Hungaria for traffic in Croatia.
