13. A transportation system for a vehicle having an upper support structure with a plurality of upper wheels capable of riding
on the lower track and a lower support structure with a plurality of lower wheels capable of riding on the upper track, the
wheels having a pair of outer sides and an inner area, the transportation system comprising:
a support structure;
a first lower track having a pair of lower rails, the lower rails supported the support structure;
a first upper track having a pair of upper ails, the upper rails spaced above the lower rails, the upper rails supported by
the support structure;

a second lower track having a pair of lower rails, the lower rails supported by the support structure, the lower rails of
the second lower track intersect the first lower track by the crossing of rails and defining a transition section including
a concave auxiliary track portion having a pair of support grooves and defining an area cut out of the rails adapted for the
wheel of the vehicle moving from being supported by the tracks over the inner area of the wheel to support of the outer sides
of the wheel by the pair of support grooves over a distance cut in the track therein allowing for the crossing of the first
lower track; and

a second upper track having a pair of upper rails, the upper rails spaced above the lower rails, the upper rails supported
by the support structure, the upper rails of the second upper track intersect the first upper track by the crossing of rails
and defining a transition section including a concave auxiliary track portion having a pair of support grooves and defining
an area cut out of the rails adapted for the wheel of the vehicle moving from being supported by the tracks over the inner
area of the wheel to support of the outer sides of the wheel by a transition section wherein the wheel of the vehicle moves
from being supported by the tracks over the inner wheel area to support of the outer sides of the wheel area by the pair of
support grooves over a distance cut in the track therein allowing for the crossing of the first upper track.

5. A transportation system comprising:a support structure including a plurality of structural arches, each of the structural arch having an apex;
a vehicle having an upper support structure with a plurality of upper wheels and a lower support with a plurality of lower wheels;
a first lower track having a pair of lower rails, the lower rails supported by the support structure;
a first upper track having a pair of upper rails, the upper rails spaced above the lower rails, the upper rails supported by the support structure;
wherein the rails of each of the tracks are located generally equidistant from the apex of each of the arches therein allowing for minimal thickness of the rails while maximizing support;
a second lower track having a pair of lower rails, the lower rails supported by the support structure, the second lower track intersecting the first lower track;
the first lower track and the second lower track each having a gap such that the rails are each spaced apart from each other;
a crossing support track having a first pair of rails underlying the first lower track and having a second pair of rails underlying the second lower track, the second pair of rails of the crossing support track intersecting the first pair of rails and adapted to engage the lower wheels of the vehicle when the vehicle passes through the gap of the lower track; and
the plurality of upper wheels of the upper support structure of the vehicle are capable of riding on the lower track and the plurality of lower wheels of the lower support structure are capable of riding on the upper track, the vehicle having at least one horizontal safety wheel for engaging one of the rails of the one of the tracks associated with the lower wheels for stabilizing against derailments, wherein the arches are spaced a specific distance d that is less than the length l of the vehicle.
