Factors reducing braking rates below the limit imposed by adhesion between wheel and rail are discussed. Braking efficiency can be related to adhesion, but only when the braking is straight line from moment of application to standstill. This is never so in practice, and the braking efficiency can therefore be considered only as an average ratio, and not the adhesion value which is the limit in maximum braking. No braking starts at the maximum rate instantaneously, nor does it usually carry on to a stop at the maximum rate. The reasons are regard for passenger comfort and the speed of equipment response. Manufacturing inaccuracies and maintenance problems which cause differences in brake cylinder air pressure are mentioned.
