US-5381309 Amtrax serving 46 American States and 3 Canadian Provinces

The American National Railroad Passenger Corporation, doing business as Amtrak is a passenger railroad service that provides medium- and long-distance intercity service in 46 contiguous United States (lacking Wyoming and South Dakota) and to three Canadian cities. It serves more than 500 destinations and operates more than 300 trains daily. Amtrax was founded 47 years ago in 1971 as a quasi-public corporation to operate many U.S. passenger rail services. 

Amtrak is no longer required by law to operate a national route system, but it is encouraged to do so. Amtrak services fall into three groups: short-haul service on the Northeast Corridor, state-supported short haul service outside the Northeast Corridor, and long-distance service known within Amtrak as the National Network. Amtrak receives federal funding for the vast majority of its operations including the central spine of the Northeast Corridor between Boston and Washington DC as well as for its National long distance routes. In addition to the federally funded routes, Amtrak partners with transportation agencies in 18 states to operate other short and medium haul routes outside of the Northeast Corridor, some of which connect to it or are extensions off of it. In addition to its inter-city services, Amtrak also operates commuter services for three state agencies including MARC in Maryland, Shore Line East in Connecticut, and Metrolink in California.
