A method for erecting a portion of a transportation structure including two assemblies of tube segments, capable of being placed under low air pressure and through which pods may travel substantially free of air friction, the method including: (a) erecting a substructure including a first plurality of girders forming a first transportation pathway and a second plurality of girders forming a second transportation pathway, the erecting step including conveying with vehicle(s) the girders along one single transportation pathway, positioning them and having the vehicle(s) return along the other transportation pathway, (b) conveying, with vehicle(s), the tube segments along one single transportation pathway, positioning them and having the vehicle(s) return along the other transportation pathway. A portion of a transportation structure is also provided.

A method for erecting a portion of a transportation structure including a first assembly of tube segments, capable of being placed under low air pressure and through which pods may travel substantially free of air friction, the method including: (a) erecting a substructure including a first plurality of girders forming a first transportation pathway and a plurality of platforms forming a service pathway, the erecting step including conveying with vehicle(s) the girders and platforms along the first transportation pathway, positioning them and having the vehicle(s) return along the service pathway, (b) conveying, with vehicle(s), the tube segments along the first transportation pathway, positioning them and having the vehicle(s) return along the service pathway. A portion of a transportation structure is also provided.

A transport system includes: a transport path housing; a first magnetic force unit provided in the transport path housing; a transport vehicle that includes a second magnetic force unit provided so as to be able to face the first magnetic force unit and is able to travel along the transport path housing while being levitated by magnetic force acting between the first magnetic force unit and the second magnetic unit; a rail on which the transport vehicle lands to be able to travel, the rail being provided in the transport path housing; and at least one moving means for moving the transport vehicle in a landing state where the transport vehicle lands on the rail, to a position where the transport vehicle is be able to be levitated by the magnetic force.

A guide tube according to an embodiment of the present invention may comprise: a tube main body member; a rib member arranged in the longitudinal direction of the tube main body member and coupled to the inner surface of the tube main body member; and a rail support member connected to the rib member.
