HŽ series 6111
The HŽ series 6111 is an electric multiple unit used by Croatian Railways (Croatian: hrvatske željeznice, HŽ), formerly the class JŽ 411 during the Yugoslav period. The vehicles were built by Ganz, Hungary. There were a few subseries of this class. A first class only (blue) series existed also at the time of the Sarajevo Winter Olympics. Today, only the white/blue coloured units exist, and are used for the Zagreb Commuter Rail and for some regional electrified railway lines in short to medium distance from Zagreb.
