7
The 7 City Point - Otis & Summer Streets via Summer Street & South Station leaves the City Point area by heading north on L Street, which becomes Summer Street to South Station. Past South Station, it turns around in a loop via Otis Street, Franklin Street, Federal Street and High Street. Some trips use East First Street and Pappas Way instead of Summer Street over the Reserved Channel to serve the Harbor Industrial Park.
Streetcars last ran on the 7 on June 19, 1953, between City Point and South Station. Very few changes have been made to the route since then, most related to closures in Summer Street.
