The surface public transport system in the city of Milan comprises 17 tram lines, 4 trolley lines, 80 urban bus lines (of which 3 run at night to substitute for the subway lines during their closing hours), and 33 long distance bus lines, in addition to 1 people-mover linking the Cascina Gobba subway station to the San Raffaele Hospital and various regional railway lines managed by Trenord. The "Area urbana" public road transport network is managed by Azienda Trasporti Milanese S.p.a together with other companies under subcontracting agreements: AGI, AIRPULLMAN, AMP, MOVIBUS, STIE and STAR.
The Milan subway system comprises four lines: M1 (red line), M2 (green line), M3 (yellow line), and M5 (lilac line). These colours are used on subway maps and in the outfitting of trains and stations. The Milan subway system is the largest in Italy, with an extension of 87.6 km. The network, which is managed by Azienda Trasporti Milanesi ATM S.p.A, was built by Metropolitana Milanese S.p.a and Metro 5 S.p.a.
The M1 line runs from north-east to west, where it splits into two, one running towards the north-west and another towards the south-west. Its terminuses are Sesto FS (in the municipality of Sesto San Giovanni), Rho Fiera (in the municipality of Rho) and Bisceglie. The M1 line intersects the M2 line at the Loreto and Cadorna interchange stations, the M3 line at the Duomo interchange station, and with the passante railway at the Porta Venezia interchange station. It will intersect the new M5 line at the Lotto station.
The M2 line runs from north-east to south. Its northern terminuses are Gessate (in the municipality of Gessate) and Cologno Nord (in the municipality of Cologno Monzese). Its southern terminuses are Abbiategrasso and Assago Milanofiori Forum, the latter in the municipality of Assago. The M2 line intersects the M1 line at the Loreto and Cadorna interchange stations, the M3 line at the Centrale interchange station, and the passante railway at the Porta Garibaldi interchange station. It will intersect the new M5 line at the Garibaldi station.
The M3 runs from north to south in a single line. Its terminuses are Comasina and San Donato, the latter in the municipality of San Donato Milanese. It intersects the other lines as follows: M1 at the Duomo interchange station, M2 at the Centrale interchange station, M5 at the Zara interchange station, and the passante railway at the Repubblica interchange station.
The M5 line, identified by the colour lilac, is the first subway line in Milan to be fullyautomated and driverless. Its terminuses are Bignami and San Siro Stadio. It is also a light subway line, with shorter trains and platforms measuring 50 meters instead of the 110 meter standard size in the M1, M2, and M3 lines. It intersects the other lines as follows: M1 at the Lotto interchange station, M2 at the Garibaldi interchange station, M3 at the Zara interchange station.
The Meneghino train, manufactured by AnsaldoBreda/Firema, is the new-generation train currently in use in the Milan subway together with traditional and refurbished trains. Its comfort and low noise levels make it the flagship train of the three subway lines. The first Meneghino trains began service in July 2009 and March 2010, respectively on the M2 line
between the stations of Gessate and Abbiategrasso, and the M3 line between the stations of Maciachini and San Donato.
Subway lines under construction
The M4 line, currently under construction, will be identified by the colour blue and will run across Milan from west to east for about 15 km, linking Linate Airport with S.Cristoforo FS and passing through the historic city centre. It will have 21 stations with various interchanges: M1 at San Babila, M2 at S.Ambrogio and with the passante railway at S.Cristoforo, Dateo, and Forlanini (new Passante di Milano subway station)
Like the M5 line, it will be light and highly technological, fully automated, and driverless.
The Milan public transport network is the largest in Italy, extending for almost 1,600 km and with a maximum capacity of 3,750,000 passengers per kilometre. With its 103 stations and 95 km of rail, the Milan subway is about as large as all other Italian subways put together (Rome, Naples, Turin, Brescia, Genoa, and Catania). It has been estimated that each one of Milan's inhabitants travels an average of 83km per year using the city's public transport. This is another Italian record.
