What are the advantages of maglev train compared with ordinary train?

Compared with ordinary wheel-rail trains, maglev trains have the advantages of high speed, low noise, stability and comfort. Disadvantages: high cost.

Maglev train has the advantages of high speed, low consumption, environmental protection and safety, and its prospect is very broad. The normal guided maglev train can reach 400-500 km/h and the superconducting maglev train can reach 500-600 km/h, and its high speed makes it superior to flying in the travel distance of 1000 to 1500 km. Because there are no wheels, no friction and other factors, it saves electricity by 30% compared with the most advanced high-speed train at present. At the speed of 500 km/h, the energy consumption per seat /km is only 1/3 to 1/2 of an airplane, which is 30% less than that of an automobile. Because there is no wheel-rail contact, the vibration is small and the comfort is good, and the maintenance cost of vehicles and tracks is also greatly reduced. The maglev train does not rub against the track when running, so the noise is very low. Its magnetic field intensity is very low, equivalent to the earth's magnetic field, far lower than household appliances. Because it is driven by electricity, the pollution caused by burning coal and oil along the way is avoided. Maglev trains generally pass through flat ground or climb hills over 4.5 meters overhead, which avoids the damage to the ecological environment caused by digging trenches.
