He says?
He says:by the end of the tests in the maglev line at yamanashi in the year 2000,it is expected that the feasibility,reliability and service suitability of the system will make it a major contender for operation in the new Tokyo-osaka rail lin.Goodman says the most high-profile results from the tests at yamanashi are the speeds achieved.the trails began with a manned train recording a speed if 421kmm/h.this was gradually raised by increments of 20-3-km/h to reach 531km/h.a further unmanned test achieved a speed of 550km/h,a world record for maglevs,and representing the maximum design speed of the vehicles,top operational speed will be 500km/h.this would establish the feasibility of a one-hour journey time between Tokyo and Osaka.
