Abstract

A guidance apparatus is used on a transit vehicle which includes separate steerable drive tires operated by a central guidance platform having four peripherally mounted wheels follow the contour of a guide rail. The guide wheels are spaced above the roadway on a guideway used by the steerable drive tires thereby providing the capability of both on-track and off-track driving of the vehicle. A steering linkage imparts the linkage of a guide plateform to one steerable drive tire and a drag link transmits the rotary motion to the second steerable drive tire.
