TOKYO - A magnetically levitated Japanese train raced to a new record Tuesday, topping its own record set just last month. The experimental maglev set the world's top speed for a train, clocking 361 mph in a test run in Yamanashi Prefecture (state), west of Tokyo, Central Japan Railway Co., which is carrying out the experiments, said in a statement. Maglev trains differ from conventional trains in that magnets lift them slightly off the track, eliminating speed-reducing friction and reducing noise. (they also cost about 100 times as much) The maglev is part of a government-financed project to develop faster...
