How many kilometers per hour does the Shanghai maglev train run?

The speed of 80% sections can exceed100 km/h; 60% of the road speed can exceed 300 km/h; In addition, there is an ultra-high-speed section of 10 km, with a speed of over 400 km/h.

The suspension distance of the track from the ground can reach 12~ 13 meters, and the train runs on the Shanghai maglev train for about 8 minutes. The model of Shanghai maglev train is basically the same as that of Germany TR08 maglev train. There are four trains that can be put into operation, divided into 4/5 sections, of which 1 is a domestic train.

merits and demerits

Maglev train has a very broad prospect because of its advantages of high speed, low energy consumption, environmental protection and safety. 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 trains. 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, but due to bumps, the maintenance cost of vehicles and tracks is also extremely high.

The maglev train will not rub against the track when it is running, so the noise is very low. Maglev trains generally pass through the flat ground or climb over the overhead hills more than 5 meters, digging mountains and ditching, which inevitably causes damage to the ecological environment. The maglev train runs on the track and is configured according to the fire protection standard of the aircraft.

Even if there are means to solve the above technical problems, it also involves another problem-money. The design investment of about 30 kilometers in Shanghai is 654.38+000 billion yuan, while the two lines in Germany, one of which is 36.8 kilometers long, will cost about 2.6 billion euros. The other section, 78.9 kilometers long, will cost 3.2 billion euros (1 euro is about equal to 8 yuan RMB). ?

In actual construction, according to the different terrain, road surface and designed transportation capacity, the cost will of course vary greatly. But in any case, a kilometer line needs at least 800 million yuan of investment, which means that the line of 1 cm will cost 8000 yuan to build.
