Portland Transportation Center is a bus and train station in Portland, Maine, United States, served and run primarily by Concord Coach Lines (18 round-trips a day)[2] and AmtrakDowneaster passenger trains (five round-trips a day).[3] It is also served by Megabus (via Concord Coach Lines), as well as the Greater Portland Metro route 1 and BREEZ bus services.[4] The station is open from 4:30 AM to 12:15 AM and from 2:45 AM to 3:15 AM.[5]
In 2019, the NNERPA Board (which governs the Downeaster service) supported a proposal to relocate the station to the mainline to avoid time-consuming backup moves.[7] A two-year study by the Maine Department of Transportation endorsed moving Amtrak service from this station to a location near Portland's original Union Station, on St. John Street.[8] A 2024 Amtrak study identified three potential locations: between Congress Street and Park Avenue, the Union Station site, and near Mercy Hospital south of the Mountain Branch junction.[9]
