Abstract
Monorail vehicle that travels on a non-featured rail with substantial profile variation and controls roll attitude, lateral location, and loading through judicious placement of the vehicle's center of gravity without using springs or suspensions. The vehicle has a bogie for engaging the non-featured rail so the center of gravity has a lateral offset rfrom the rail centerline to produce a roll moment Ndetermined by vehicle's mass and value of r. The center of gravity also has a vertical offset r. The bogie uses first and second assemblies for engaging the rail to produce a pair of surface normal reaction forces to thus control roll attitude and loading by the placement of the center of gravity, thereby enabling accurate alignment of the monorail vehicle.
