North Station

North Station is a commuter rail and intercity rail terminal station in Boston, Massachusetts. It is served by four MBTA Commuter Rail lines - the Fitchburg Line, Haverhill Line, Lowell Line, and Newburyport/Rockport Line - and the Amtrak Downeaster intercity service. The concourse is located under the TD Garden arena, with the platforms extending north towards drawbridges over the Charles River. The eponymous subway station, served by the Green Line and Orange Line, is connected to the concourse with an underground passageway.

The concourse of the station, named for longtime Boston Celtics coach Red Auerbach, is located under the TD Garden arena, with two entrances from Causeway Street, as well as entrances from Nashua Street to the west. Five island platforms serving ten tracks run north from the concourse. Just north of the platforms, a pair of two-track drawbridges cross the Charles River. Eight commuter rail lines and three Amtrak services terminate at South Station about 1 mile to the south, with no direct rail link between the two stations. The proposed North–South Rail Link would link the two halves of the commuter rail system, with new underground platforms at both stations.
