The isolated section of the track just in front of the signal is switched off by the relay when the signal is red so a train will stop automatically at the red signal. This project uses the 555 times in bistable mode.\u003c\/span\u003e\u003cbr\u003e\u003cbr\u003e\u003cspan\u003eIn this \u003c\/span\u003e\u003cstrong\u003eModel Railway Signal Project Kit\u003c\/strong\u003e\u003cspan\u003e when the train passes through the first switch which is connected to a fixed distance from the railway signal gate means the first switch is pressed momentary then red led on and the dc bulb is OFF while when the train crosses the second switch, the signal is green and dc bulb is ON.
