World Power: China launched the fastest train in the world

The Chinese launched the world’s fastest passenger train with a design speed of 620 km / h. Today it is a record among land transport: the previous champion from Japan, the Seriel L0 (A07) train, produced 603 km / h.

True, so far this is all a battle of prototypes: in real conditions, trains of this type travel slower. The fastest train in normal operation runs from Shanghai to Shanghai airport, and for safety reasons it accelerates to no more than 431 km / h.

This is what a train that has already been in operation in China looks like:

And this is the new record holder:

They created it quickly: development began at the end of 2016, and in the summer of 2020, the first line-up was already being tested. The train is built on the principle of magnetic levitation (for which it received the abbreviated name maglev ).

Instead of the usual rails, a concrete base is used here, on which a T-shaped metal sheet is laid. The train does not have wheels, and its body wraps around the canvas on both sides (therefore, it does not fly off it). It moves along the tracks due to the powerful force of the electromagnetic field, hovering above the monorail at a height of 1-2 cm.

Specifically, this train will be able to connect up to 10 carriages with up to 100 passengers in each.

Electromagnetic transport is good because:

  • Has a higher KDP due to the absence of mechanical friction. Energy in maglev is used 3 times more efficiently than in a car.
  • Allows you to develop a higher speed than conventional trains (in theory, today’s technology can be improved, and speeds of 6000-8000 km / h can be achieved);
  • Creates less noise;
  • Has half the turning radius, which means it allows you to create more flexible routes.

There is also a minus: the infrastructure for the Maglev must be built separately, which China is already actively engaged in. At the end of 2020, there were almost 38 thousand km of high-speed rail lines in the country. The investment should pay off: Maglevs are considered the best transport for short and medium-haul destinations. At distances of up to 1000 km, they can be a real competitor to civil aviation.
