The Series N700 is billed by Japan Railways as the world's fastest bullet train in service (France's faster TGV train has been used only to break speed records), with a top speed of 186 mph.
It's the first bullet train to be equipped with an air spring-powered active tilting system, allowing it to whip around corners without slowing down. Special fabric hoods cover the gaps between cars, turning the train into one long, seamless, aerodynamic unit.
Despite all these improvements, the 5-hour trip to Fukuoka will be shortened by a mere 10 minutes. More important, though, the journey will be quieter and more comfortable, and it will use 19 percent less energy than current bullet trains.
World's Fastest Train Specs
Fast Corners:
The N700 leans into curves, tilting 1 degree more than the angle of the track. This lets it maintain a speed of 168 mph on a curve with a 1.6-mile radius, up from 156 mph for existing trains.
Power Saver:
Like another emblem of Japanese green design, the Prius, the N700 uses regenerative braking to save power. More cars have motors than on older trains, helping the N700 recover as much energy as possible.
Up to Speed:
The N700's acceleration is 30 percent greater than its predecessor's, the Series 700. The train goes from 0 to 60 mph in 37 seconds — not bad, considering that the vehicle weighs 700 tons.
