ABSTRACT:
A train having at least a pair of control cabs spaced along the train interconnected electrically. Electric signals transmitted between the control cabs allows for fluid braking signals to be propagated from both control cabs toward each other. Each car of the train includes a device for modifying a test signal transmitted between the control cabs in response to a specified condition. The signal modify device can be a tuned circuit and may indicate brake status or a hot journal.
