AUTOMATED METRO
"As one of the main European operators of automated metros, we are willing to make this strong know-how and experience available for Authorities and Citizens".
Milan
In Italy, we run two automated metros in Milan: the M5, a 15-km line covering 21 stops with a capacity of 50 million passengers per year and the automated line M4. Inaugurated in November 2022, M4 connects the Linate Airport with the city centre in only 12 minutes and serves 86 million passengers per year.
Copenhagen
We have acquired a significant international experience by managing four automated metro lines in the city of Copenhagen through Metro Service A/S, with a transport capacity of 135 million passengers per year.
Since 2008 we have been managing the M1 and M2 lines, comprising 22 stations covering approximately 21 kilometres.
We also run the Cityringen M3, a circular underground line of 15.5 km inaugurated in 2019, with 17 stations.
In 2020 the automated line M4 was inaugurated, composed of 13 stations, spread over 12km.
Thessaloniki
We manage the Thessaloniki automated metro, the first driverless line in Greece.
The metro serves the second largest Greek city by population, with over one million inhabitants. It spans 10 kilometers along an east-west axis, featuring 13 stations and serves 313,000 passengers daily with train headways of about 3 minutes. By reducing road traffic by approximately 60,000 vehicles each day, it is estimated to prevent 212 tons of CO2 emissions per day, promoting clean urban mobility.
The construction of the Thessaloniki Metro uncovered remarkable archaeological discoveries that are showcased in the Stations and museums, with “Venizelou” Station standing out as the largest archaeological site integrated into a major technical project worldwide.
Future plans include an extension with five additional stations reaching Kalamaria, near the city’s airport.
International benchmark
We actively participate in the UITP Observatory of Automated metros, a body commissioned to disseminate and share the most current and relevant knowledge about automated metro lines.
METRO
"The metro lines are the backbone of a mass transit system, moving millions of people every day through the city. Our commitment is to offer a top-quality service, supported by technological innovation"
We manage the entire Milan metro network, covering approximately 114 km and representing almost half of the total metro networks in Italy.
To ensure high performance and safety service standards, our fleet is modernized through periodic renewal plans (the average fleet age is around 5 years), trains are subject to an accurate ordinary and extraordinary maintenance and our OCC, with "cutting-edge technology", is active 24/7 for the integrated management of the metro network.
Our key numbers
TRAM
"We run one of Europe's largest tramway networks, moving over 300,000 passengers every day. Through our six depots, we directly manage operations and maintenance of vehicles and infrastructure".
We manage 17 lines and 400 vehicles, reaching an overall network of over 157 km in the city of Milan. A modern and efficient service based on a historic network that has been serving the city centre since the early twentieth century.
The fleet, mainly composed by modern vehicles, is subject to a renewal process so that all new trams are accessible, equipped with cutting-edge technologies and all travel comforts.
The fleet also includes 125 “Carrelli” historical trams that are constantly maintained through a dedicated activity to preserve their charm together with the highest efficiency and to integrate them with all the needed technology.
BUS
“With our buses we serve the city of Milan and the surrounding municipalities. We have a significant experience in green vehicles management and we are converting more than 1,200 buses to electric”.
We run 160 lines and almost 1,200 urban and suburban buses in Milan, ensuring high standards of efficiency, maintenance and service. In 2025, ATM won 18 bus lines near Paris. Service starts March 2026.
Our buses circulate 24/7: at night they replace our metro system, which is under maintenance, ensuring the service for late- and early-workers and people that want to enjoy the city around the clock.
Sustainability is a comprehensive approach that we adopted to deliver our service through green vehicles, low-impact depots and charging infrastructures.
On-demand Transport
The ATM On-demand Transport service responds to the need for safe night travel in 15 Milan districts. It is operated with shuttle buses that connect several Milan neighbourhoods to the metro stations, circulating from10 pm to 2 am. Complete safeness, flexible stops and high frequency are the major added value to the service.
ATM is also experimenting with Demand-Responsive Transport (DRT) during daytime hours, serving three municipalities in the first suburban area.
TROLLEYBUS
“In our depots, technicians work with the utmost efficiency and accuracy to ensure that our trolleybus fleet can have the best performance”.
We serve the Milan area with 4 trolleybus lines and 133 vehicles. In particular, with our circle lines we connect the whole city, moving over 150,000 passengers every day.
Maintenance of vehicles and infrastructures is a key asset to support these important lines.
In order to meet our sustainability goals, a new generation of zero-emission and fully-accessible trolleybuses have been introduced in our fleet.
CABLE
“Cable transport systems are efficient and sustainable modes of transport that can fit perfectly into a public transport network, and a can bring added value to a tourist place”.
We manage the Como – Brunate cable railway which opened in 1894 and connects the city of Como with the village of Brunate, in Lombardy. It is a semi-automated cable system with a strong tourist appeal, as well as being the quickest way of travelling between these two towns.
During the 2013-2019 period, the annual number of passengers increased by 64% to over 1,2 million passengers.
We also manage a people mover connecting a metro station on the M2 line with the San Raffaele Hospital in Milan, an automated cable system on tyres, equipped with platform doors.
Since 2023, ATM manages the Varese Vellone–Santa Maria del Monte cable railway, inaugurated in 1911. Located within the municipality of Varese in Lombardy, this cable railway leads to the Sacro Monte (Holy Mount) of Varese, religious complexes standing on hilltops which are UNESCO World Heritage Sites that has been a popular destination for visitors and pilgrims for centuries.
Additionally, we operate the Cablecar Argegno–Pigra, which connects Argegno, a coastal location of Lake Como, with Pigra, a mountain village. This line, inaugurated in 1971, has been managed by ATM since 2024.
