Magnetic trains more annoyingly noisy than the old-fashioned kind. High-speed trains gliding along with magnetic levitation look as if they should be sleek and silent.

The maglev train produces high noise levels at speeds of more than 250 kph that may affect the health and well-being of residents near the line.
Maglev trains do not create direct pollution emissions and are always quieter in comparison to traditional systems when operating at the same speeds [6]. In the area of noise emissions, maglev trains are superior in every way to wheel/rail systems, not to mention airplanes.
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.
Disadvantages of Maglev TrainsComplications resulting in accidents will usually lead to high human fatalities. Maglev trains are much more expensive to construct than conventional trains because of the high number of superconducting electromagnets and permanent magnets required, which are usually very costly.
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.
Thanks to linear induction, there are no moving parts in the propulsion system, and the magnetic suspension means that maglev trains do not touch the ground.
The Maglev has significantly lower CO2 emissions compared too the traditional InterCity train at 300 kph, mainly due to its lower energy usage. At 400 kph the Maglev has almost half the CO2 emissions than an average motor car and a massive five and a third times less than a short haul airline flight.
Roughness and irregularities on the wheel and rail surfaces are a source of noise and vibration. Rail joints and squats on the rail cause a familiar clickety-clack sound as train wheels roll over them.
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.
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). Assuming 70kg for the average commuter passenger this gives us an efficiency of (116 kg-km/MJ) for maglev.
This reaction between the magnets creates a magnetic field. The field lifts the train off of the track. This lets air flow between the train and the guideway. The trains never touch the track; they hover just above the track.
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.
The MAGLEV train provides a sustainable and cleaner solution for train transportation by significantly reducing the energy usage and greenhouse gas emissions as compared to traditional train transportation systems.
