ABSTRACT:
A passenger transportation system includes a transport vehicle which travels in the interior of an elongated tunnel formed from a series of concrete modular conduits. The cross-section of the conduit interior includes a bottom surface on which the vehicle travels, a pair of spaced apart side walls, and a pair of spaced apart upper wall surfaces extending inwardly from the side walls and on opposite sides of an elongated slotted opening extending lengthwise along the top of the conduit tunnel. The transport vehicle is supported by a suspension system which includes a plurality of carrier frames, each having guide rollers traveling along the bottom surface, the side walls, and the upper wall surfaces of the conduit. The guide rollers are supported by respective biasing elements which urge the guide rollers into continuous contact with the walls of the tunnel to keep the vehicle centered in the tunnel during transit. The top of the conduit tunnel is at ground level and only the top section of the vehicle projects though the central top opening of the tunnel above ground level. Doorways are provided in portions of the vehicle top section for allowing passengers at round level to enter the passenger compartment of the vehicle.
