SCIENTISTS at Southwest Jiaotong University in China have reportedly built a maglev train that could reach 1800mph (2900km/h).
A vacuum is used to minimise air resistance.
Project lead Dr Deng Zigang claims it could be used for military or space launch systems.
Maglev trains use electromagnetism to lift the train off a track and to provide propulsion.
By removing the need for contact with a surface via wheels, friction is substantially reduced and speed can be increased.
They are also smoother to ride than surface-supported alternatives and are less affected by the weather.
The fastest passenger-carrying maglev train can travel at up to 268mph.
