Milan has an extensive internal transport network and is also an important transportation node in Italy, being one of the country's biggest hubs for air, rail and road networks. Internal public transport network includes the Metro, the Suburban Railway, the tram and bus network, as well as taxi, car and bike sharing services.
Early public transport service in Milan dates back to 1801, operated with horse-drawn carriages. After the relocation of the Capital of the Italian Kingdom in Milan in 1805, national and international transport services were inaugurated, all operated with carriages, to Vienna, Marseille and several Italian cities. Transport via the Navigli canals was also an important transport mode in that period.
The first bus line was opened in 1827, connecting Milan to Lodi. The first railway, to Monza, was inaugurated in 1840.
The Milan Metro is a rapid transit system, running mainly underground, serving Milan and other surrounding cities. The network consists of 4 lines, identified by different colors and numbers:
Milan Metro has a total length of 100 km (62 mi), serving 113 stations, making it the longest metro network in Italy. The system carries about 1.15 million passengers per day. A new line, Line 4, is currently under construction.
The suburban railway service consists of 12 lines connecting Milan to the greater metropolitan area:
The system was brought together from existing lines and the construction of the new Passante, an underground railway line passing through the city. The service began operation in 2004 and now comprises 125 stations. Several extensions are planned.
The Tram network comprises 17 urban lines and 1 interurban line (Milan - Limbiate). The system is more than 170 km long and is the biggest network in Italy.
