Just look for the big red M . There are plans to construct a Metro in Turin. The fare structure is integrated between the various modes. Buy a flat-fare ticket or a weekly pass in advance from a roadside or station machine. Information is available from the ATAC booth in front of the Termini station.
Trolleybuses also run in a number of other towns.
In larger cities, fares are generally pre-purchased from machines or shops. Bus fares generally at a standard rate per run can be bought in packets of five or multiples and are fed into a stamping machine on boarding the bus. In Rome and Milan they are relatively expensive, with extra charges for night service, luggage and taxis called by telephone. All charges are listed on a rate card displayed in the cab with an English translation. Taxis can only be hailed at strategically located stands or by telephone.
