Maglev train
"Maglev" trains float on a magnetic cushion, which reduces friction.  The trains have an aerodynamic design. This allows them to reach speeds of more than 310 mph (500 kph), or twice as fast as Amtrak's fastest commuter train.  In comparison, an airliner used for long-range flights can reach a top speed of about 560 mph (900 kph).
