The world's fastest train is one thing to experience once in your life. Maglev, also known as "magnetic levitation," is a transportation method using magnetic levitation to move the train without ever touching the ground. Basically, it levitates with the use of magnets making it faster that the usual trains that use cables and rollers. Another advantage of using magnetic levitation is it reduces friction with the railway which allows the train to move faster.

According to the BBC, Shanghai's Maglev Train connects from Pudong International Airport going to the metropolis with speeds up to 430 kilometers per hour making it a little bit faster than the speed of sound. With the technological advancement the train exhibits, indeed it is the fastest commercial train in the world.

The Maglev train is located in the middle of Pudong International Airport. Unlike other trains, it glides through the track eliminating friction to occur which can slow down the train. The science behind the engineering is simple as the train uses magnets to move.

Maglev trains are less expensive to operate that the traditional trains--this is because it does not use any rollers under its track but magnetic levitation or the use of magnets that cause the movement from point A to point B. Without the rolling friction the train is easier to maintain and manage.

Another advantage of the this train is there is no fuel involved making it cost efficient. Aside from that no fuel is burned making it a non contributor to pollution which causes climate change.

The Maglev train does not produce any sound like the other traditional trains. The answer to this is simple, Maglev is frictionless making the ride very smooth, fast and accomodation to the passengers.

According to India Today, the construction of the Maglev train involves a lot of money because it requires a lot of rare earth elements like the scandium, yttrium and 15 lanthanides. The construction might be expensive but it saves a lot of money in the end, and also helps by not adding pollution that causes climate change.
