ABSTRACT:
A switching system for a high-speed railway system has no moving parts on the road bed, all of the switching decisions and actions being taken aboard a vehicle travelling on the system. A pair of parallel main running rails commences to diverge at the switching point, and two pairs of parallel main running rails leave the switching point. The outer rail of each pair of outgoing rails is a continuation of one of rails incoming into the switching point. A pair of switching rails is between the main rails and each is parallel to the opposite continuing rail. The truck on a vehicle on the rail system has flange running wheels which engage the main rails. A pair of wide switching wheels has flanges closer together than the flanges on the running wheels. The switching wheels can be shifted laterally so that the flange on one of the switching wheels engages a switching rail and guides the vehicle toward the pair of main rails parallel therewith. Preferably the switching rails have a central portion at a higher elevation than the adjacent main rails for lifting the running wheels off the main rails through the switching point.
