The Acela is Amtrak's flagship passenger train service along the Northeast Corridor (NEC) in the Northeastern United States between Washington, D.C., and Boston via 13 intermediate stops, including Baltimore, Philadelphia, and New York City. Acela trains are the fastest in the Americas, reaching 150–160 miles per hour (240–260 km/h), qualifying as high-speed rail, but only for approximately 40 miles (64 km) of the 457-mile (735 km) route.
