I wonder how fault tolerant maglev systems are. The tracks must have to be incredible straight and precise to have a train hovering over it at 600km/hr over those kinds of distances. With traditional rail it's relatively simple to fix up parts of a track or have areas where trains need to slow down to accommodate tricky sections of track. Must be a lot more difficult to repair a maglev track section?
