There are only three countries in the world that currently have operational Maglev Trains: China, Japan, and Korea. Maglev trains are much more efficient than traditional trains and hold the speed record for trains (603km/h).

Due to the huge cost of running a maglev over very long distances, the hovering trains have been ruled out for the planned HS2 line connecting Manchester with London and Birmingham by 2033.
Maglev trains are hard and expensive to build. They don't have a good safety record. There isn't established infrastructure to maintain the trains, or people who know how.
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.
Cost: Maglev train technology is significantly more expensive than conventional high-speed rail. HS2 is already a highly expensive project, and adopting Maglev technology would further increase the cost.
There are several disadvantages to maglev trains: - Maglev guide paths are more costly than conventional steel railway tracks. Because the magnetic coils and material used in this setup are very costly. - Maglev trains require an all-new set up right from the scratch.
High-speed rail in the United Kingdom is provided on five upgraded railway lines running at top speeds of 125 mph (200 km/h) and one purpose-built high-speed line reaching 186 mph (300 km/h).
Automation of London Underground rolling stock has been partially implemented since the introduction of automatic train operation on the Hainault to Woodford section of the Central line in 1964. It is currently in use on six lines. Transport for London plans to extend this to remaining lines by 2023.
Maglev trains require very straight and level tracks to maintain high speeds. This necessitates extensive viaducts and tunneling, making construction costly.
In fact, you are floating! This dreamlike experience is will soon be a reality thanks to Japan's famous Maglev bullet trains, the fastest train in the world. Japan is already well known for its extensive Shinkansen train system, which has been in operation since 1964.
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.
Project developers claim that Maglev would benefit clean air and climate change due to the number of cars it would remove from the road. However, the draft environmental impact statement shows that Maglev would actually increase regional transportation energy consumption by 39% — enough energy to power 88,900 homes.
Even if the power goes out, levitation forces keeps the train in the air while it is traveling at high speed. The vehicle comes safely to a stop rather than suddenly falling onto the track.
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.
It is a maglev (magnetic levitation) line using partly evacuated tubes or tunnels. Reduced air resistance could permit vactrains to travel at very high (hypersonic) speeds with relatively little power—up to 6,400–8,000 km/h (4,000–5,000 mph). This is 5–6 times the speed of sound in Earth's atmosphere at sea level.
Transrapid (German: [t?ans??a'pi?t]) is a German-developed high-speed monorail train using magnetic levitation. Planning for the Transrapid system started in 1969 with a test facility for the system in Emsland, Germany completed in 1987.
Cost concerns over innovative railThe primary challenge facing maglev trains has always been cost. While all large-scale transportation systems are expensive, maglev requires a dedicated infrastructure including substations and power supplies and cannot be integrated directly into an existing transportation system.
