A system is provided that uses small carrier vehicles that operate along electrified guideways and use standardized connections to automatically carry passenger cabins, freight loads and automobile platforms to desired destinations. Front and rear bogies of the vehicles pivot about front and rear vertical turn axes and carry direction control wheels that cooperate with guide ribs along tracks for selective control of movement to either of two exits from a Y junction. The guideway provides a protected environment for error-free data transmissions made through closely spaced inductive couplings between monitoring and control circuits along the guideway and control circuits of the carrier vehicles. Control circuitry is provided to obtain highly reliable control of vehicle speed and of starting, stopping and merge operations.
