Railway system for use on railway tracks of different widths, has conical or tapered annular step formed around rim of each twin-track wheel

摘要

A conical or tapered annular step (6) is formed around the bearing surface of the rim (8) of each twin-track wheel. The step is also located within an ideal pitch corresponding to the distance (D) between the centers of the track rails (1,1') of two different width railway tracks.
