Abstract
A method and system for providing true failsafe control of an electronic braking system by a train control system which controls a switch that supplies power to the electronic braking system. When the train control system determines that it is necessary to activate the train's brakes, it controls the switch so as to remove power to the electronic braking system, which results in activation of the train's brakes. In highly preferred embodiments, the switch is of a type that is normally open and that requires the presence of an electrical signal to close the switch to supply power to the electronic braking system. In such embodiments, any loss in power to the train control system will result in a loss of signal to the switch, thereby causing activation of the train's brakes.
