A surge suppression circuit for a track circuit is provided. The surge suppression circuit comprises a first surge protection device including a first pair of silicon avalanche diodes and a second surge protection device including a second pair of silicon avalanche diodes. The first surge protection device is connected on a first connection line between a first terminal of a railroad signaling electronic equipment to be protected from a surge and a first terminal of a first rail of two physical rails. The second surge protection device is connected on a second connection line between a second terminal of the railroad signaling electronic equipment and a second terminal of a second rail of the two physical rails. The first surge protection device and the second surge protection device are connected to an earth ground terminal.
