There are both high-speed, intercity maglev systems (over 400 kilometres per hour or 250 miles per hour), and low-speed, urban maglev systems (80–200 kilometres per hour or 50–124 miles per hour) under development and being built.

The line uses the German Transrapid technology. The Shanghai maglev is the world's first commercial high-speed maglev and has a maximum cruising speed of 431 km/h (268 mph), making it the fastest train service in commercial operation. Shanghai Shentong Holdlings Co.,Ltd.
Using strong electromagnets, Transrapid's maglev technology allowed the train to levitate above the tracks, reducing friction and enabling the train to travel at very high speeds—eventually reaching speeds in excess of 300 mph (500 kph) in some cases.
As noted above the Maglev trains are capable of traveling at speeds nearly twice as fast as the bullet trains. However, the use of such extreme speeds in commercial travel seems unlikely. Whereas Maglev trains travel at speeds of up to 400 or 600kph, bullet trains travel at a modest 320kph.
Maglev trains are “driven” by the powered guideway. Any two trains traveling the same route cannot catch up and crash into one another because they're all being powered to move at the same speed. Similarly, traditional train derailments that occur because of cornering too quickly can't happen with Maglev.
Maintaining correct distance between train and guideway is not a concern (Lee, 2006). The drawbacks are that sufficient speed needs to be built up in order for the train to levitate at all. Additionally, this system is much more complex and costly to implement.
Because maglev trains require entirely new guideways, cars, and power specifications, they must be built from scratch. Despite their decades-long allure, implementation costs can be prohibitive relative to HSR. Today there are only six operational maglev trains—three in China, two in South Korea, and one in Japan.
Background on Maglev Train, Vactrain, HyperloopThey are even faster than regular maglev trains, but are even more expensive to build. Hyperloops are a proposed type of transportation that would use a low-pressure tube to send people or cargo through a tube at high speeds.
The new Acela will operate at top speeds of 160 mph vs. today's fleet, which operates at top speeds of 150 mph. Amtrak's new Acela fleet is scheduled to enter service on the NEC in 2024.
Their speed, however, will be limited by the complexities of the 457-mile route, which is old, curvy and carries a mix of freight, commuter and intercity trains. Most Amtrak trains travel between 110 mph to 145 mph in the corridor, depending on the track and proximity to stations.
On the train itself are superconducting electromagnets, called bogies. When stopped, the train rests on rubber wheels. To begin motion, the train moves forward slowly on these wheels, allowing the magnets beneath the train to interact with those of the guideway.
Present Maglev systems cost 30 million dollars or more per mile. Described is an advanced third generation Maglev system with technology improvements that will result in a cost of 10 million dollars per mile.
The Superconducting Maglev is equipped with a braking system capable of safely stopping a train traveling at 311mph. Regenerative braking is normally used for deceleration, but if it becomes unavailable, the Superconducting maglev also has wheel disc brakes and aerodynamic brakes.
Fastest Train in the World – 357.2 MPHThe current world speed record for a commercial train on steel wheels is held by the French TGV at 574.8 km/h (357.2 mph), achieved on 3 April 2007 on the new LGV Est. The trainset, the track and the cantenary were modified to test new designs.
Most Shinkansen currently operate at a maximum of 300 kph (186 mph), but some hit 320 kph (200 mph). The long noses are designed to reduce sonic booms in tunnels.
See China's first high-speed overwater bullet train lineThe new line in China's Fujian province goes along the west side of the Taiwan Strait, with the trains running as fast as 217 miles per hour. Why is Saudi Arabia signing so many soccer players?
Compared to highspeed passenger rail, maglev passenger rail consumes roughly twice the power per passenger kilometer. For commercial freight I found an efficiency figure of 520 ton-miles per gallon (660 kg-km/MJ).
How Maglev Trains Work. The magnetized coil running along thetrack, called a guideway, repels the large magnets on the train'sundercarriage, allowing the train tolevitate between 0.39 and 3.93 inches (1 to 10 centimeters) above the guideway. ... Maglev trains float on a cushion of air, eliminating friction.
