Metro

The subway in Boston is the oldest in the US. It was opened shortly before the one in Chicago on September 1, 1897, as Tremont Street Subway. The former section is now part of the tram Green Line.

The red line was the last of the four original Boston subway lines (Green, Orange, and Blue) to be built. The section of the Harvard and Eliot Yard station connects Park Street and the Tremont Street Tunnel that opened on March 23, 1912. The Broadway station included the second floor and included its own tram tunnel, abandoned in 1919 because most of the lines truncated in Andrew. Currently, the second floor is part of the mezzanine.

During snowstorms, the MBTA runs an empty train during non-service hours to keep the railroad tracks clean.

The Red Line is connected with the Orange line in Downtown Crossing, the Blue Line in State and the Green Line in Haymarket and North Station. It connects with Amtrak and the Commuter service in Back Bay and North Station, and Ruggles in Roxbury and Forest Hills. The current name was assigned in the 1960s and comes from Calle Orange, an old name for a section of Washington Street that is south of downtown Boston where the Washington Street Tunnel passes.

The East Boston Tunnel, opened in 1904, was the first underground section in the world to operate under the ocean. The line changed its name to the Blue line on August 26, 19653 as part of the new nomenclature system of the Boston Metro based on colors.

The Silver line is the only line of the bus of rapid transit of the Metro of Boston. The line consists of 22 stops and is operated by the Massachusetts Bay Transportation Authority (MBTA). The Silver Line is composed of 4 routes: The SL1 functions between Logan Airport and South Station via Waterfront; the SL2 operates from Design Center to South Station via Waterfront; after Dudley to South Stations operates the SL4; between Dudley and Downtown operates the SL5 via Washington Street.

The Green line is a light rail and is part of one of the four rapid transit lines of the Boston Metro. The system consists of 12 stations and is operated by the Massachusetts Bay Transportation Authority or BMTA. It is the oldest line of the Boston Metro, known locally as the 'T'. The Green line operates underground under downtown Boston and at street level in other areas. With an average of 232,000 passengers a day it is also the most used light rail system in the country. The line gets the name "Green" because it goes through an area called Emerald Necklace in Boston. The main Green Line serves between Lechmere and Kenmore stations. There are also another 4 branches on the Green line: the B Branch runs from Blandford Street to Boston College station; the C Branch functions from St. Marys Street to Cleveland Circle station; the D Branch operates between Fenway station and Riverside, the E Branch functions between Prudential and Heath Street station.
