@albert.mureithi: Automated Railway Crossing The barrier (gate) is lowered automatically to stop road traffic when a train is approaching. Sensors on the track (or signaling system from the rail network) detect an approaching train. A control unit sends a signal to the crossing system. Flashing red lights and alarms activate to warn drivers and pedestrians. The automatic barrier arm lowers to physically block vehicles from crossing. Train passes safely Barrier raises again #engineering #automation #security #easylife
