Amtrak Network Amtrak operates a nationwide rail network, serving more than 500 destinations in 46 states, the District of Columbia and three Canadian provinces, on more than 21,400 miles of routes. It is the nation's only high-speed intercity passenger rail provider, operating at speeds up to 150 mph (241 kph).

As of early 2026, Amtrak operates a vast national rail network that covers approximately 21,400 route miles. This extensive system serves more than 500 destinations across 46 states, the District of Columbia, and three Canadian provinces. While Amtrak owns and maintains about 363 miles of the Northeast Corridor (NEC)—the high-traffic line between Boston and Washington, D.C.—the majority of its mileage (roughly 97%) is operated over tracks owned by "host" freight railroads like BNSF, Union Pacific, and CSX. The network is categorized into three main service types: the high-speed Northeast Corridor, various State-Supported short-distance corridor routes (under 750 miles), and the iconic Long-Distance routes such as the California Zephyr and the Empire Builder. For 2026 travelers, these 21,400 miles represent the "arteries" of American passenger rail, providing a high-value alternative to domestic flights.
