South Station (also signed as South Station Under) is a transfer station on the MBTA rapid transit Red Line and bus rapid transit Silver Line, located at Summer Street and Atlantic Avenue in downtown Boston, Massachusetts. It is a part of the South Station complex, the second busiest transportation center in New England. Eight MBTA Commuter Rail and three Amtrak intercity rail services terminate at South Station; many of those passengers then transfer to the subway to reach other destinations in the city. With 25,037 daily boardings by a 2013 passenger count, South Station is the busiest station on the MBTA subway system.

A station serving South Station was located on the Atlantic Avenue Elevated. Service on the Atlantic Avenue "El" was discontinued on September 20, 1938. The structure itself was torn down in the spring of 1942. Before stairs were added, passengers wishing to change lines from the underground station — itself opened on December 3, 1916 — had to use a paper transfer and go outside to change trains.

In 1957, the original fare lobby and the rounded top of the tunnel to the west were removed during construction of the Dewey Square Tunnel. The tunnel was rebuilt with a flat ceiling, while the fare lobby was moved to the east closer to the South Station headhouse.

A second renovation began around 1980 and consisted of the adding of a passageway to already existing stairs and escalators upstairs to the main terminal building. An entrance was also added to the Federal Archives Building as well as a passageway under Summer Street connecting the other street entrances. In 1985, the Red Line platforms were extended 60 feet on either end to allow 6-car trains.

The final renovation was triggered by the massive highway project known as the "Big Dig". Since the Red Line tunnel beneath Summer Street is perpendicular to Atlantic Avenue, where the new I-93 northbound tunnel was to be built, builders had to tunnel under the tracks. After the first tunnel was complete, another tunnel was added along with a station for the Silver Line. Since the new tunnel was built at the former fare level, another fare level was constructed a level above. This allowed combined access for the Silver and Red lines. The original lobby that was destroyed was replaced by stairways. This project was completed at a cost of 35 million dollars.
