Maglev Train (1x5)

:

Experts analyse the work of engineers including Sir Nigel Gresley, who engineered the world's fastest steam train in 1938 and Eric Laithwaite, whose linear motor made frictionless travel a possibility. These innovators influenced the engineering of the Shanghai Maglev, the fastest passenger train in operation on Earth, which broke numerous engineering boundaries in its construction. Held in place by a series of electromagnets, it levitates on an air gap of 10mm and is able to reach a top speed of 431kms per hour.
