what is it?

SŽ 342 is a series of single-system four-axle electric locomotives that make up the rolling stock of Slovenian Railways. Since it has "only" four axles compared to its six-axle contemporaries, the railwaymen somewhat mockingly called it a moped. As the locomotive proved to be one of the most reliable, the nickname "Tsar" became established for it.
