High-speed rail (HSR) is a type of rail transport network utilising trains that run significantly faster than those of traditional rail, using an integrated system of specialised rolling stock and dedicated tracks.

Under the most common international definition of high-speed rail (speeds above 155 mph (250 km/h) on newly built lines and speeds above 124 mph (200 km/h) on upgraded lines), Amtrak's Acela is the United States' only true high-speed rail service, reaching 150 mph (240 km/h) over 49.9 miles (80.3 km) of track along the Northeast Corridor.

High-speed trains are lightweight and aero-dynamic, able to accelerate quickly. Inside, the ride is quiet and smooth. The smallest trains have twice the seats as the largest planes, but offer greater comfort and legroom. In many countries, high-speed trains operate on both high-speed and conventional track in a single journey.
