Railway system for transporting passengers or other cargo, uses twin track wheels, each having half of track width difference wider than track width of certain track rail

摘要

A railway system uses twin track wheels (8), each having a pair of track widths. Half of the difference between track widths is wider than the track width of certain track rail (1,1'). A step (6) around the periphery of the twin track wheel lies between the track widths. Each track width of the track wheel assumes an outward tapering shape.
