Modern railway crossing detector using Multivibrator

Sensor, railway gate, magnetic contact technique.
In the rapidly flourishing country like ours, accident in the unmanned level crossing are increasing day by day. No fruitful steps have been taken so far in these areas. Our project report deals with automatic railway gate operation, implemented in unmanned level crossings at remote areas detection of train approaching the gate can be sensed by means of the reed switch placed on either side of the gate. Train arrival and departure sensing can be achieved by means of magnet properties .When the wheels of the train over, the reed switch which are placed near the track sense and this acts as a signal to the circuit indicating train arrival. Yellow signal appears for the road user, once the train cuts the reed switch placed before the 2 km before the gate. Once yellow light appears after approximately 3 seconds, it automatically blinks the red light that indicates train is crossing. When the train has passed level crossing it operates the cancel reed switch which switch off the light until the next train arrives. This can be implemented in manned level crossing also, as manned errors can be eliminated by automation.
