ABSTRACT:
A microprocessor-based, electropneumatic brake control system for a locomotive having a pneumatic back-up control valve which includes a quick release valve for maintaining a release condition of the control valve during dynamic braking. An arrangement is provided to prevent the control valve from applying during a trainline-initiated emergency application prior to the dynamic brake becoming ineffective following dynamic brake knockout, in order to avoid the possibility of a wheel skid.
