A transportation system for rapidly loading people from a platform into and from a plurality of cars. The system includes an elongated trackway which extends along a platform. Trolleys extend between the trackway and the cars supporting the cars on the trackway. The cars have side doors extending along the length thereof which open towards the platform to provide access to a single row of seats carried in the vehicles facing the doors. The doors can be automatically opened and closed upon reaching the platform. The trackway includes upper lower and intermediate rails upon which upper, lower and intermediate wheels, carried by the trolleys, engage to provide an interlocking relation therebetween. A vertically extending keel is carried by at least some of the vehicles for engaging power driven wheels that are positioned along the trackway. An adjustable pressure bearing wheel is carried on the opposed side of the keel from the power-driven wheels for maintaining the keel in driving contact with the power-driven wheels. The power-driven wheels are connected to a D.C. motor/generator for selectively propelling the cars along the trackway and braking the cars.
