Intro
Since 1804, The first full-scale working railway steam locomotive was built in the United Kingdom invented by Richard Trevithick, a British engineer born in Cornwall. Then on September 27, 1825, Locomotion No. 1 became the world’s first steam locomotive to carry passengers on a public line invented by George Stephenson at his son Robert’s company, the Robert Stephenson and Company. Today, technology is rising and there is a new way of making trains fast and efficient like the Maglev Train. It is a system of train transportation that uses two sets of magnets: one set to repel and push the train up off the track which is called Levitation and Propulsion. Levitation is the action of rising or causing something to rise and hover in the air. There are several techniques in levitating a maglev train, there is Electrodynamic, Electromagnetic, and Inductrack. Electrodynamic is the technique used to interact electric currents with magnetic fields or with other electric currents. Electromagnetic is relating to the interrelation of electric currents or fields and magnetic fields. And Inductrack uses only unpowered loops of wire in the track and perslide magnets on the vehicle to achieve magnetic levitation. Magnetic Levitation has various uses. The common point in all applications is the lack of contact and thus no wear and friction. This increases efficiency, reduces maintenance costs, and increases the useful life of the system. Levitation is also used for maglev trains, contactless melting, magnetic bearings and for product display purposes. You can create a simple levitation by putting 2 same poles of a magnet. 2 same poles means to repel while 2 opposite poles means to attract. While Propulsion is the action of driving or pushing forward. It is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields. The electrical current is used to either create an opposing magnetic field, or to charge a field, which can then be repelled. You can create a simple magnetic propulsion by putting a battery (with 2 magnets in between) in a suspension spring/coil/wire. Also, the word maglev comes from the combination of magnet and levitation hence the named maglev train because of magnetic levitation. There are advantages and disadvantages of a maglev train. These advantages are high level of safety. Synchronized propulsion makes collisions between maglevs unimaginable. There are also no derailments either. They have also incredible speed which is about 500 kph faster than a bullet train for about 320 kph. Maglev Trains are eco-friendly which means they can use elevated guideways to minimize the disturbance to the natural environment, including wildlife. They are also the most quietest transportation system than other traditional transportation systems that produces noise. They are also disadvantages like Maglev guide paths are bound to be more costly than conventional steel railways. Because the magnetic coils and material used in this setup are very costly. The other main disadvantage is the lack of existing infrastructure. Construction estimates for the maglev line, which would require carving out an entire new right of way, range between $10 billion and $12 billion for the 40-mile Washington-Baltimore stretch. 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. They can be considered expensive because they can’t use the hundreds of thousands of miles of traditional rail track that crisscross the world. The trains used to change tracks in a ‘pinched loop’ system. Six commercial maglev systems are currently in operation around the world. One is located in Japan, two in South Korea, and three in China. Japan’s L0 Series Maglev is the fastest train in the world, with a speed record of 374 mph or 602 km/h. It’s 34 times faster than the slowest passenger train, Barkakana–Sidhwar Passenger in India for about 18 km/h (11 mph). It could go the distance from New York City to Montreal in less than an hour. Maglev trains sometimes cause accidents like the Lathen Train Collision. It occurred on 22 September 2006, killing 23 people. Thanks to English inventor Eric Laithwaite who invented first commercial maglev train in 1984 in Birmingham. But for future generations, Hyperloop trains will be a success surpasses Maglev train. But still, Maglev trains can be considered as our futuristic train because of it’s features. This is the next era of evolution of trains.
