A warning display of railway crossover gates is provided to enable a vehicle driver to recognize the operation status of the crossover gate in nights by displaying the operation status of the crossover gate. A warning display is implemented on a railway crossover having a signal lamp(100) and a crossover gate(200). A display panel(10) having plural LED(Light Emitting Diode) lamps(11) for displaying a warning sign is fixed on the crossover gate(200). A PCB(Printed Circuit Board) is formed on a rear portion of the display panel(10). The PCB is wired to the LED lamps(11) and is covered by a case to be connected to the signal lamp. The PCB includes a crossover gate operation detection circuit, a lamp controller, a power switch, and a power circuit. The crossover gate operation detection circuit detects the operation status of the crossover gate(200). The lamp controller outputs a signal to turn on and off the LED lamps(11) according to the detected signal from the crossover gate operation detection circuit. The power switch repeats on/off switching processes according to the control signal of the lamp controller. The power circuit supplies power to the LED lamps(11).
