Tremont Street Subway The Tremont Street Subway in Boston's MBTA Subway system is the oldest subway tunnel in North America and the third oldest worldwide to exclusively use electric traction (after the City and South London Railway in 1890, and the Budapest Metro's Line 1 in 1896), opening on September 1, 1897.[2][3] It was originally built to get streetcar lines off the traffic-clogged streets, instead of as a true rapid transit line. It now forms the central part of the Green Line, connecting Boylston Street to Park Street and Government Center stations.
