In 1906, an Elevated Light Rail was built for the World's Fair Exhibition. The line linked the two main areas of the Fair between the Piazza d'Armi and the Arena Stadium close to the city centre. The line was dismantled 8 years later. It can be considered the first Italian electric public transport line totally independent of other railway lines.
The first line (Line M1) of the subway was opened in Milan in 1964 after 7 years of work, from Lotto to Sesto Marelli (21 stations). In 1969 the second line (Line M2) from Caiazzo to Cascina Gobba (7 stations) was opened. In the 1960s and 1970s the network of 2 lines was completed, and both lines have 2 different spurs. Line M1 has a west branch from Pagano Station, and Line M2 has an east branch from Cascina Gobba to Gessate, running far away in the metropolitan area with 10 stations.
In 1990 the third line (Line M3) was opened, with 5 stations. The other 9 stations on Line M3 opened to the southeast in 1991, and northwest to Maciachini Station in 2004.
In 1997 opened the Passante Ferroviario, an underground railway line of 11 km, with 9 stations, where different trains run (Trenitalia and FNM).
Finally, in 1999 a shuttle line based on a people mover system opened between Cascina Gobba station and the San Raffaele Hospital, called Metrò San Raffaele (light green) with 2 stations.
In March 2005 the Line M2 station at Abbiategrasso (south branch from Famagosta) opened.
The Line M1 station of Rho-Fiera Milano also opened to passengers on 30 March 2005 (just before Regional Elections on 3-4 April), but it was closed again on 3 April, and re-opened in September 2005. The intermediate station of Pero (between Molino Dorino and Rho-Fiera) opened on December 2005.
Since Milan won the bid for the World Exposition in 2015, the city received special funds for the construction of the new lines, which are going to be completed between 2010 and 2012.
It will run from the western suburb of Lorenteggio to the eastern side of the city to Linate Airport. The line has been approved, but not funded, by Italian Government in March 2006. A south-eastern branch was projected running from Forlanini station to Santa Giulia new neighborhood. On the other side the line will be extended from San Cristoforo to Corsico, Cesano Boscone and Trezzano sul Naviglio suburbs. Excavations have not begun yet.
The first half of the line will run from Garibaldi station (links with Line M2 and "Passante Ferroviario") north to Monza city centre. The construction of the first part of the Line, from Garibaldi to Cà Granda, with intermediate stations at Isola, Zara, Marche, Istria, started in October 2007. The second part of Line M5, from Cà Granda to Bignami, will have an intermediate station at Bicocca Università II°. The second part of Line M5, from Bignami to Monza, will have stations at Sesto Parco Nord, Cinisello Valtellina, Monza Bettola, Monza Centro.
After the merge of the former plans for the lines M5 and M6, the new project for the line M6 will be planned as a separation from the northern branch of line M1, in order to relieve it of the expected amount of visitors travelling to the World Exposition pavilion. The line will be separated from Pagano station, going to Baggio on the west and Tibaldi on the south.
In the summer 2006 was presented the project about a monorail people-mover on the southern side of the city, running from the I..E.O. along Via Ripamonti to the district of Gratosoglio.
The Suburban Railway Service (called S) consists of 8 lines that connect Milan to the greater metropolitan area:
The FNM Network is over 300 Kilometers long, with 120 stations and 750 trains per day (frequency of 3 minutes in the morning and evening rush hours). In the year 2004 the FNM transported more than 51 millions of passengers.
Ferrovie Nord Milano (FNM) Lines:
The FNM has six stations in the city of Milan:
