**Line 1** is the first underground [rapid transit](/source/Rapid_transit) line built in [Milan](/source/Milan), [Italy](/source/Italy). It is part of the [Milan Metro](/source/Milan_Metro) and it is operated by [ATM](/source/Azienda_Trasporti_Milanesi). Works on the line began in 1957, and the first part was opened on 1 November 1964,[4][5] running from Sesto Marelli to Lotto station. The line is also called **Red Line** (*Linea Rossa* in Italian), as it is visually identified by red signs. Due to its premiership, the line gave its red color to the Milan Metro logo.

## Route

The line runs underground from the northern suburb of [Sesto San Giovanni](/source/Sesto_San_Giovanni) to the city centre, then to the western district with two different branches, one northwest to [Rho](/source/Rho%2C_Lombardy), the other to the west to Bisceglie. It is 27 km (17 mi) long and serves 38 underground stations.[6]

Key points served by the line are *[Duomo](/source/Piazza_del_Duomo%2C_Milan)*, considered the center of Milan; [Castello Sforzesco](/source/Castello_Sforzesco) (with [Cairoli](/source/Cairoli_(Milan_Metro)) station); *[Cadorna](/source/Milano_Cadorna_railway_station)*, one of the busiest stations in Milan and in Italy; *[Corso Buenos Aires](/source/Corso_Buenos_Aires)* (with stations [Porta Venezia](/source/Porta_Venezia_(Milan_Metro)), [Lima](/source/Lima_(Milan_Metro)) and [Loreto](/source/Loreto_(Milan_Metro))), an important shopping street; and [Rho Fiera](/source/Fiera_Milano), one of the largest fairgrounds in the world.[7]

## History

The mezzanine floor of the [Amendola station](/source/Amendola_(Milan_Metro)) just before opening in 1964.

The [San Babila station](/source/San_Babila_(Milan_Metro))'s poster during the 1960s.

On 6 April 1952 the city administration asked for a project of a metro system and on 6 October 1955 a new company, Metropolitana Milanese, was created to manage the construction of the new infrastructure.[8] The project was funded with [₤](/source/Italian_lira) 500 million from the municipality and the rest from a loan. The construction site of the first line was opened in *viale Monte Rosa* on 4 May 1957.[8] Stations on the new line were designed by [Franco Albini](/source/Franco_Albini)-[Franca Helg](/source/Franca_Helg) architecture studio. [Bob Noorda](/source/Bob_Noorda) designed the famous wayfinding and signage system.[8]

At first, stations were designed without the mezzanine floor. However, these were added to the final design to allow street crossing and the use of gates to collect tickets.

The line from *Lotto* to *Sesto Marelli* (21 stations) opened on 1 November 1964, after seven years of construction works.[9]

## Rolling stock

There are 3 types of trains running on the line: revamped original trains, the ["Meneghino"](/source/AnsaldoBreda_Meneghino) trains, and the "[Leonardo](https://en.wikipedia.org/w/index.php?title=AnsaldoBreda_Leonardo&action=edit&redlink=1) [[it](https://it.wikipedia.org/wiki/Leonardo_(treno))]" trains.

The original first series trains were phased out between 2014 and 2015. The track gauge is the 1,435 mm (4 ft 8+1⁄2 in) [standard gauge](/source/Standard_gauge). The entire line is electrified by means of a [third](/source/Third_rail) or [fourth rail](/source/Railway_electrification_system#Fourth_rail) at 750 V DC.[10]

Among the 63 trains running on the line, 20 entered service between 1964 (opening of the line) and 1970. Those trains were replaced by the "Meneghino" trains,[2] and more were replaced by the "Leonardo" trains. Subsequently, the original first series trains were retired and dismantled.[11] These new trains fully replaced the older, non-upgraded series still operating on Line 1.

On November 17, 2024, the first of 21 "Galileo" trains produced by Hitachi Rail at the Reggio Calabria plant was delivered for Line 1.[12][13][14] These trains are set to completely replace the refurbished original sets. Their entry into service is scheduled for 2025.[12]

## Extension

An extension towards the north from [Sesto Primo Maggio](/source/Sesto_1%C2%B0_Maggio_(Milan_Metro)) to [Monza Bettola](https://en.wikipedia.org/w/index.php?title=Cinisello/Bettola_(Milan_Metro)&action=edit&redlink=1) is currently under construction. It is expected to be completed by 2023.[15] The new section will be 1.9 km (1.2 mi) long with 2 stations (*Sesto Restellone* and Monza *Bettola*), entirely underground. The total cost will be €206 million.[16]

An extension of the western branch from [Bisceglie](/source/Bisceglie_(Milan_Metro)) towards the city limits has been approved in 2019. The new stations will be located at [Baggio](/source/Baggio_(district_of_Milan)), via Valsesia and at Quartiere Olmi. The national government will provide €210 million, while the total cost is estimated at €350 million.[17] The public construction contract for a total of €362 million was awarded in June 2025. The construction work is planned to last 6 years 3 months.[18]
