Young Black Haired Girl Travels In The Old Train

In most cases, high-speed rail travel is time- and cost-competitive with air travel when distances do not exceed 500 to 600 km (311 to 373 mi), as airport check-in and boarding procedures may add as many as two hours to the actual transit time. Also, rail operating costs over these distances may be lower when the amount of fuel consumed by an airliner during takeoff and climbout is considered. As travel distance increases, the latter consideration becomes less of the total cost of operating an airliner and air travel becomes more cost-competitive.
Some high speed rail equipment employs tilting technology to improve stability in curves. Examples of such equipment are the Advanced Passenger Train (APT), the Pendolino, the N700 Series Shinkansen, Amtrak's Acela Express and the Talgo. Tilting is a dynamic form of superelevation, allowing both low- and high-speed traffic to use the same trackage (though not simultaneously, of course), as well as producing a more comfortable ride for passengers.
• Maglev
In order to achieve much faster operation over 500 km/h (310 mph), innovative Maglev technology has been researched for years. The Shanghai Maglev Train, opened in 2003, is the fastest commercial train service of any kind, operating at speeds of up to 430 km/h (270 mph). So far, however, Maglev has not been used for inter-city mass transit routes.
