Fastest trains in the world

​

​

There are a few countries in the 21st century that use efficient electromagnets, or Maglev Trains, to create high-speed trains. Using the fundamental ideas of magnets to substitute the old steel wheel and track trains, these trains float over guideways. There is no rail friction, which means these trains can reach speeds of up to hundreds of miles an hour.   

 

 

Advantages and disadvantages of Maglev Trains
   

​

High velocity, however, is just one main advantage of maglev trains. There is much less noise, turbulence than typical, earth-shaking trains since trains barely (if ever) hit the track. Less turbulence and pressure results in fewer mechanical breakdowns, ensuring that weather-related disruptions are less likely to occur in maglev trains. Unlike traditional trains, maglevs have several other advantages. They are less expensive to operate and maintain because components do not wear out easily, and there is no rolling friction. It ensures that the train uses fewer components as parts do not need to be replaced regularly. Derailment is very unlikely due to the design of the wagons and maglevs, and the maglev wagons can be wider than traditional wagons, allowing more space inside and making them more comfortable to ride. Since no fuel is consumed, maglev trains emit little or no emissions, and the lack of friction makes the trains very quiet (both inside and outside the cars) and offers a very smooth ride for passengers. Finally, unlike conventional railroads, maglev systems can run on higher ascending grades, eliminating the need to excavate tunnels or level the terrain to accommodate them. The greatest impediment to maglev construction is the need for completely new infrastructure that cannot be combined with existing railroads and will clash with existing highways, railroads, and air routes. One thing to remember in designing maglev rail systems, apart from construction costs, is that they require the use of rare-earth elements, which may be quite expensive to recover and refine ​[1] such as:
 

• ​scandium

• yttrium

• 15 lanthanides

   
 

History of the uprising

​

 

The French-born American engineer Emile Bachelet filed the first patents for magnetic levitation (maglev) technologies all the way back in the early 1910s. In 1904, an American professor and inventor, Robert Goddard had invented a paper outlining the idea of maglev levitation even before that. Based on this futuristic vision, it was not long before engineers began planning train systems. Soon, they believed, passengers would board magnetically propelled cars and zip at high speed from place to place, and without many of the traditional railroads' maintenance and safety concerns. The colossal distinction between a maglev train and a conventional train is that there is no engine for maglev trains, partially not the type of motor used to pull typical train cars along steel tracks. The engine is inconspicuous for Maglev trains. The magnetic field created by the electrified coils in the walls of the guideway and the track combines to propel the train instead of using fossil fuels [2].

   

Quick connections between cities

​

On a cushion of air, Maglev trains float, eliminating friction. This lack of friction and the aerodynamic designs of the trains enable these trains to achieve unprecedented ground transport speeds of more than 500 kph (310 mph), or twice as fast as the fastest Amtrak commuter train.
A Boeing-777 commercial aircraft used for long-haul flights can, in comparison, reach a top speed of about 562 mph (905 kph). Developers say that cities up to 1,000 miles (1,609 kilometres) apart will eventually be linked by maglev trains. At 310 mph, in just over two hours, you could travel from Paris to Rome.   
Some maglev trains can run at even faster rates. In October 2016, during a short run, a Japan Railway maglev bullet train blazed all the way to 374 mph (601 kph). These speeds give engineers hope that the technology will be functional for routes that are hundreds of miles long.  
Only Germany and Japan developed maglev train technology and tested their train prototypes so far. By 2027, Japan plans to develop the Chuo Shinkansen, a long-distance high-speed maglev line that will link Nagoya ----> Tokyoover a distance of 286 kilometres (178 miles), with an extension to Osaka (514 kilometres [319 miles] from Tokyo) planned for 2037. The Chuo Shinkansen is scheduled to run at 500 kilometres per hour (310 miles per hour) and take 67 minutes to travel from Tokyo to Osaka [3].
