A transportation system is disclosed that includes a monorail (100) along a column-supported rail (113) and a movable weight system (510) that repositions and/or accelerates a movable weight (550) along its rail to counterbalance a moment associated with weight and/or a centrifugal force of monorail relative to the column (222). Also disclosed is a linear induction motor (400, LIM) system that enables LIM to tilt and thereby remain close to rail, which mitigates potential thrust losses and/or air losses. Further disclosed is an air bearing system (300) where the air bearing (325) has compliance and resilience that minimizes air loss between the rail and the bearing. Additionally disclosed is a rotatable wedge system (1000) that essentially expands and/or contracts automatically to maintain an adjacency between two rail portions. Further still, disclosed are embodiments where LIM's attachment to assembly provides assistance to lessen air pressure needed for air bearing.
