Abstract
A system is provided for temporary protection operation of at least one controller box for a railroad switch turnout in a powered mode or non-power mode depending on the railroad configuration and independent of the controller box. A normal controller box is coupled to the normal switch point and includes a block slidably received within the housing based on moving the normal switch point to establish at least one pair of electrical contacts within the housing. A controller is coupled to the controller box to verify a pair of compressed contacts to determine that the normal switch point has moved to the normal position to cause the controller box to send an open signal to a pair of switch connections. The controller also verifies a pair of extended contacts to determine that the normal switch point has failed to move to the normal position to omit to cause said controller box to send an open signal to the pair of switch connections and maintain each respective switch connection to shunt the stationary stock rails.
