Public transport in Milan and Lombardy
The public transportation system in Milan includes:
- four subway lines (#1 - red, #2 - green, #3 - yellow, #5 - purple );
- one (mostly underground) suburban rail link (AKA "Passante");
- about 70 surface lines operated with tramsand buses.
The entire network is operated by Azienda Trasporti Milanesi, more commonly known as ATM.
Their website provides complete information on lines, schedules, fares, etc.:

The subway operates roughly from 6 AM to midnight every day (lines #1, 2, and 3 are operated by bus throughout the night 7 days a week). Trams and buses start about an hour earlier and run until an hour or so later; #90 and 91 buses operate 24 hours a day, 7 days a week. 'Night bus' lines run on Friday and Saturday nights.
A few tram lines (including #1, which runs through most of the city center and near the central train station) are still operated with vintage trams built in the 1920's; ten of those vehicles were shipped to the USA and are now in use on San Francisco's 'F' streetcar line: http://www.streetcar.org/streetcars/1811/
A trip on one of those trams is an attraction in and of itself!
To find out connections throughout the Lombardy region (bus, rail, etc..), check the Lombardy regional government's journey planner.
Tickets must always be bought before boarding, and must be promptly stamped every time you board a bus or tram, or at subway/train turnstiles. The standard urban ticket is € 1.50 and is valid 90 minutes from stamping.
In March 2014, the Municipality of Milan, together with ATM, published a call for free of charge ATM travel cards for Ph.D. students; this initiative may be repeated in future, and updated information (in Italian) may be found in this area of the ATM website (Path: Home > Services > Subscription > ATM 2019 unemployed).
Also, a public bike sharing service is available: bikeMi
