Linate Airport and downtown Milan are connected in just 12 minutes thanks to the opening of two new M4 subway stops, "Tricolore" and "San Babila."
The blue line will be in service from Monday through Sunday from 6:00 AM to 12:30 AM.
M4 intermediate stops at: Tricolore, Dateo, Susa, Argonne, Forlanini Station and Repetti.
Thanks to the interchange with the rail link at the Dateo and Forlanini stops, Linate can thus also be reached by train, integrating into the regional rail transport network.
The NM4 line replaces the M4 during the night from the airport to San Babila from 00.30am to 5.30am from Monday to Friday and on public holidays. Same times also from San Babila to the airport.
On Saturday the service runs from Linate between 12:30 a.m and 5:30 a.m, whereas from San Babila between 01:00 a.m and 5:30 a.m.
In the coming months there will be technical tests on the entire infrastructure and circulation requested by the Ministry of Transport. During the test days, which can only be carried out in the absence of passengers, M4 will be closed and the trains will be replaced by buses. M4 will be closed and replaced by BM4 buses on the following days: 8, 9 and 10 March, 3, 4, 5, 6, 7, 8 and 9 April. More info here
