ABSTRACT:
This invention relates to a railway locomotive brake control apparatus operably either manually by an engineer or automatically in response to a change in a train control signal indication to a more restrictive indication to effect a brake application on the locomotive and a train of cars hauled thereby unless the automatic train control brake application is suppressed by the engineer manually effecting a full service brake application. When the engineer thus manually effects a full service brake application upon the occurrence of the more restrictive signal indication, the fluid under pressure released from the train brake pipe to cause this brake application is used to temporarily suppress the automatic train control brake application so long as fluid under pressure is being released from the train brake pipe to atmosphere via a restriction. Thereafter, the fluid under pressure supplied to brake cylinders to effect the brake application automatically effects a permanent suppression of the automatic train control brake application.
