China’s \”sky train\”, which uses magnets and artificial intelligence, floats beneath an elevated track.

Southern China is home to the 2,600-foot long experimental rail. A maglev train is typically propelled by a liner motor and glides above the track. It’s supported by magnetic repulsion. This train, on the other hand, travels at 50 mph under its track. It is about 32 feet high and does not make physical contact with rails.

Local authorities have said that after some tests, the line can even be increased to 4.7 miles with a top speed of 75 mph.
