Acela Express
Amtrak intercity rail to Boston is provided through four stations: South Station, North Station, Back Bay, and Route 128. South Station is a major intermodal transportation hub and is the terminus of Amtrak's "Northeast Regional", "Acela Express", and "Lake Shore Limited" routes, in addition to multiple MBTA services. Back Bay is also served by MBTA and those three Amtrak routes, while Route 128, in the southwestern suburbs of Boston, is only served by the "Acela Express" and "Northeast Regional". Meanwhile, Amtrak's "Downeaster" to Brunswick, Maine terminates in North Station, and is the only Amtrak route to do so.
