High speed transportation system

A high speed transportation system comprising:

• a self-supporting tubular conduit and a train, said train formed of a plurality of units, including at least one transport capsule and a drive vehicle for propelling the train through said tubular conduit;
• said conduit including longitudinal bearing surfaces extending the length thereof;
• said transport capsule and said drive vehicle including anti-friction bearing members formed on outer surfaces thereof and structured to engage said longitudinal bearing surfaces on said conduit;
• said longitudinal bearing surfaces and said anti-friction bearing members being complimentary and aligned for guiding said train through said conduit;
• and,
• said capsule including an expandable end structure, moveable between a closed and open position to provide access to the interior of said capsule, said end structure having anti-friction bearing members on outer surfaces thereof cooperating with said longitudinal bearing surfaces;
• whereby opening said end structure when said capsule is moving through said conduit provides a braking action between said anti-friction bearing members on said end structure and said longitudinal bearing surfaces.
