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!
