Abstract
A tire path, guidebeam, electric rail configuration for a guideway in a people mover system comprises a roadway structure having a pair of spaced tire paths forming a vehicle running surface. A guidebeam is disposed along a centerline between the tire paths to provide generally vertical guidance surfaces above the tire running surface for generally horizontal guidewheels on the vehicles. First and second electric rail units are substantially identically structure and extend along the roadway structure between the tire paths to provide conductive surfaces above the tire running surface for electric collection by brush assemblies on the vehicles. Together, the electric rail units have a predetermined number of electric rails to provide power and signal circuits for the vehicles. The first and second electric rail units are supported on opposite sides of the tire path centerline and at substantially equal distances from the centerline to enable turnaround vehicle operation. Further, the first electric rail unit includes three elongated and electrically isolated power rails and one elongated and electrically isolated signal rail, and the second electric rail unit includes one elongated…
