Maglev has a major drawback, its carriages not orbit, unlike the train track from a railroad track with the turnout into other tracks. Thus, if the two tracks of two-way traffic, the train on a track only from a starting point towards the end, to the end, backtrack.

There is a magnetic levitation, and the shortcomings of the car it should not be changed, do not like a track from one of you can train tracks with trains depart to another track. In this way, if you are two tracks, two-way traffic on the A train tracks can only be driven from a starting point, to t

Magnetism aerosol has a big shortcoming, its compartment cannot change the axle, does not look like the orbital train to be possible to enter another railway rail from a railway rail with the aid of the rail switch.As the matter stands, if is two tracks bidirectional passes through, on an orbital tr

Maglev has a major shortcoming in its interior cannot orbit, unlike the train track from one track to another track with turnouts. In this way, if it is a two track bi-directional passage, a train on the tracks can only be moved from a starting point to the finish, after to the end, backtrack.
