Reasons are advanced why processes of adhesion in braking may differ from those in traction, and limitations of adhesion-measuring machines are discussed; it is shown how nature of variation of braking torque with velocity may affect driver's manner of applying brakes; incidence of pickup from 2000 brake applications on three different types of brake (cast-iron tread, nonmetallic tread, and disk) are studied to investigate effect of load, effect of moisture, and effect of speed on adhesion; incidence of pickup is found to be less for loaded than for empty train and greater for wet than for dry rails, so confirming known facts and justifying particular method of approach.
