Acela launch on the Northeast Corridor (2000)
Amtrak introduced Acela Express service between Boston and Washington, marketed as America's first high-speed train. The service used tilting trains capable of 150 mph but ran on existing tracks shared with commuter and freight rail.
Acela became Amtrak's most profitable service and the dominant air-shuttle alternative on the Boston-New York-Washington corridor.
Average speeds have stayed well below international high-speed rail because of curves, bridges, and shared track; even the new NextGen Acela tops out at 160 mph in short bursts.
Acela is the asterisk on every claim about U.S. high-speed rail. Brightline West, on a brand-new dedicated alignment with no freight sharing, is a direct test of what U.S. rail can do when it isn't constrained by century-old infrastructure.
