Most railway wheels are axi-symmetric, having a constant cross-section around the azimuthal direction. As an example of a typical wheel structure, the cross-section of a standard UIC freight wheel with a diameter of 0.92 m is shown in Figure 4.1.Many wheels are now constructed as a single piece structure rather than having a separate tyre, but …

In principle, the range shown in Fig. 4.4 for s > 0.01 is not stable, i.e. if the slip increases, the coefficient of adhesion jumps from adhesion to the lower coefficient of sliding and the wheel locks during braking or spins ("skids") during propulsion. Since these processes are more sensitive in the wheel/rail system than in a motor ...
