Thruway Motorcoach is Amtrak's system of Amtrak-owned intercity coaches, locally contracted transit buses, through-ticketed local bus routes and taxi services to connect Amtrak train stations to areas not served by its railroads. Train and Thruway Motorcoach tickets are purchased together from Amtrak for the length of a passenger's journey, and the connections are timed for convenient dedicated and guaranteed-reliable transfers between the two services. In addition to providing connecting service to unserved areas, some Thruway Motorcoaches operate as redundant service along well-established passenger rail corridors to add extra capacity.
California has the most extensive network of Thruway Motorcoaches in the nation.
Amtrak establishes temporary thruway motorcoach service when normal rail service encounters disruptions.
