THE MOVEMENTS OF RAILWAY VEHICLES ON THE TRACK AND THE FORCE ARISING THEREFROM

A critical analysis is given of the interaction of flanges and rails, together with a resume of the scientific principles involved. The friction arising between wheel and rail is fundamental for all railway transport. The frictional force R is equal to or less than the product of the frictional factor f and the wheel load Q, which are the variable quantities. As the direction of force R coincides with the resulting sliding motor between wheel and rail, its action is opposed to the direction of motion. Force R determines not only rolling resistance, but also that due to curves, guiding pressure, security against derailment, maximum tractive and braking power, axle strain, wear of rail and flange, and--last but not least--freedom from hunting. Methods to determine the precise position and value of R are discussed.
