Defining high-Speed Rail
Stephen Mattingly: Conventional rail typically operates at speeds under 80 mph (129 kph).Higher-speed rail falls between 90 and 125 mph (144 to 201 kph). High-speed rail is defined as 150 mph (241 kph) or faster, and requires different infrastructure than slower rail lines.
Current High-Speed rail in the U.S.
As of December 26, 2023, there are limited sections of true high-speed rail currently operating in the United States. The Acela Express, running along the Northeast Corridor between Boston and Washington D.C., reaches speeds up to 150 mph on certain segments, but average speeds are lower due to track sharing with freight and regional trains.
