The Milan Metro Line 3, (Linea Tre in Italian, also known as M3) is a subway line serving Milan, Italy. The line is part of the Milan Metro and is operated by ATM. Construction began in 1981 in order to be ready for the 1990 Football World Cup. It is also called the Yellow Line (Linea Gialla) as it is identified by yellow signage.
The line connects the south-eastern suburb of San Donato Milanese to the north-western area of the city passing through the city centre. It is 17.1 km long with 21 stations.
A proposed south extension to Paullo is currently on hold due to lack of funds.
The proposal for a third metro line was approved by Milan municipality in 1977. The route was chosen based on a study of main traffic routes in previous years. The final project was presented in early 1981 and works on the new line began on 8 September of the same year. The first section, from Centrale to Duomo was opened on 3 May 1990, just before the beginning of the World Cup. However, only a shuttle service was active between the two terminus. The line was extended to Porta Romana at the end of the year.
New extensions to Sondrio on the north and to San Donato on the south opened on 12 May 1991.
Works on the new line slowed down during the following years. Zara station was inaugurated only on 16 December 1995 and Maciachini on 8 December 2003. The last extension (4 stations on the north) opened in early 2011.
There are 3 types of trains running on the line: the original 1989-1990 trains, revamped original trains and the new AnsaldoBreda Meneghino trains. Trains use an overhead line providing a voltage of 1,500 V DC. The track gauge is the 1,435 mm (4 ft 8 1⁄2 in) standard gauge.
