ABSTRACT:
A railway vehicle braking system is provided with snow-brake control means operable in freezing temperatures for overriding the normal full brake release condition in a vehicle coasting or traction situation to apply a small brake force for prolonged periods to engage blocks or shoes on the vehicle wheels to reduce icing. The snow brake control means itself includes an override arrangement for, from time-to-time, effecting complete but temporary release of such a snow brake application so as to enable whatever slack adjustment is necessary to thereby insure continued validity of the brakes for a service application despite brake wear resulting from prolonged snow brake application.
