"This video shows the guidance by railway tracks. The model explains the interaction between railway wheels and railway tracks. It is shown how design features such as a conical tread, a rigid axle and a flange are necessary to impede jamming and override. Together they prevent the wheel, and consequently the train, from derailing."
