There is no true metro in Croatia, though many residents refer to the local commuter railway as "the Metro". The Zagreb - Rijeka line also resembles a metro. There also appears to be a plan for a new metro, but nothing has yet been done.
According to the LRTA's system list, Zagreb operates 51.4 km of tram track.
The following photo and stats were graciously offered by Dejan Vuletic of Zagreb.
