ATM - Azienda Trasporti Milanesi is a company 100% owned by the Municipality of Milan. Historical operator of public transport in the capital of Lombardy and in the metro area, the Group is also present in Denmark and Greece.

Committed to the transformation of Milan

In Milan we manage the entire system of lines, trams, trolleybuses and buses together with integrated mobility services: bike sharing, parking at the public transport network, parking and access to limited traffic areas.

The future of public transport in Milan is electric

Our transition plan includes the renewal of the bus fleet with electric vehicles, charging infrastructure, self-production of energy and the conversion of depots and maintenance processes.

Technological innovation, operational excellence and consolidated know-how

From the different modes of public transport (traditional and automatic metros, trams, buses, trolleybuses, cableways, bike sharing) to the engineering of means and infrastructures, from the digitization of the travel experience to smart mobility solutions with a strong innovative component: ATM's experience and expertise cover the entire value chain of mobility services, with solutions capable of making public transport an increasingly reliable alternative, efficient and attractive.

Italian roots with a strong vocation for internationalization

We are among the first operators in Europe in the management of automatic metros. In addition to the M4 and M5 lines in Milan, since 2008 we have been managing the entire Copenhagen metro network, and from 2024 the first driverless metro in Greece, in the city of Thessaloniki. The ability to compete also on international markets represents the value on which we want to continue to build our growth.
