Local train, bus, tram and metro services were hit on Monday by a nationwide strike proclaimed by several unions representing workers in the sector, according to ANSA.
Rome transport company Atac said five metro stations were closed, Cornelia, Baldo degli Ubaldi, Repubblica, Vittorio Emanuele and Ponte Lungo, but added that the three lines of the underground remained operational.
Likewise, Milan's ATM said all five metro lines were running there.
The impact of the strike on commuters in Naples was limited, while in Bologna it led to an increase in road traffic.
