A monorail transportation system utilizing generally inverted channel shaped rail members for supporting personal transit vehicles which are each suspended from the rails by a carriage having traction motor propelled drive wheels engageable with the rail channel and spaced apart vehicle supporting guide wheels. The vehicles have aerodynamically contoured bodies provided with lift surfaces which provide varying degrees of lift in accordance with vehicle speed and angle of attack to reduce mechanical friction in the carriage and structural loading on the r...
An elevated monorail transport system including at least a main trackway adapted to support a plurality of vehicles for traversal along said trackway, said vehicles each comprising traction carriage means including support wheels for supporting said vehicle on said trackway, propulsion motor means and propulsion wheel means continuously engaged with a portion of said trackway for propelling said vehicle along said trackway, said vehicle also comprising a body connected to said traction carriage means and having an aerodynamic lift surface formed thereon ...
