Metrosassari
Metrosassari, also called Sassari tramway, Sassari tram-train or Sassari metro-tramway is the commercial name of a tram-train line in Sassari, Italy, operated by the regional public transport company ARST (Azienda Regionale Sarda Trasporti).
Despite having been built in the early 2000s, in the urban section the line was built with single track and narrow gauge, to connect with the same gauge used in the secondary railway lines in the island.
