THE LIMITS OF ADHESION

A comparison of adhesive data for 15-types of electric locomotives shows that at least ten are overpowered. The adhesion coefficient is defined and the relationship between tractive effort and wheel slip is shown. Measures to prevent wheel slip are discussed. The fluctuations of wheel load and adhesion on dry, wet, and oily rail are illustrated. It is concluded that elaborate mechanical axle-load-equalizers which have been used to improve adhesion are not as important as carefully designed suspension and damping systems.
