A history spanning over 100 years
the transport company ATM (Azienda Tranvie Municipali) inaugurates its first commercial connection from the central Piazza Colonna to the working-class district of Santa Croce in Gerusalemme. With the opening of line III (as it was called to distinguish it from the SRTO lines, company that managed most of the urban network under an almost monopoly regime), the Municipal Council, led by the mayor Ernesto Nathan, launches the “Municipal tram network project” which gradually managed to redeem the entire existing network.
