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 Downeaster is a 145-mile (233 km) passenger train service operated by Amtrak and managed by the Northern New England Passenger Rail Authority (NNEPRA), an agency of the state of Maine. Named for the Down East region of Maine, the train operates five daily round trips between North Station in Boston, Massachusetts, and Brunswick, Maine, with ten intermediate stops.
