A magnetic levitation (maglev) train in Japan has broken the world speed record by hitting 366mphi on 16th April. It beat the previous record of 361mph set in 2003 – but the new record could be smashed within days. Another test run is scheduled during which the train’s speed could reach 373mph.Maglev trains use a magnetic charge to lift and move the train cars above a guide way. Japan is hoping to export the technology to the US and has even offered to part-cover the costs of a new line between New York and Washington DC.
