which Amtrak's flagship service along the Northeast Corridor is  currently the only services in the country
High-speed rail in the United States Plans for high-speed rail in the United States date back to the High Speed Ground Transportation Act of 1965. Various state and federal proposals have followed. Despite being one of the world's first countries to get high-speed trains (the Metroliner service in 1969), it failed to spread. Definitions of what constitutes high-speed rail vary, including a range of speeds over 110 miles per hour and dedicated rail lines. Inter-city rail in the United States with top speeds of 90 mph or more but below 125 mph is sometimes referred to as higher-speed rail. The Acela Express (reaching 150 mph) and the Northeast Regional (reaching 125 mph) are currently the only services in the country (the Metroliner was discontinued in 2006).
