MODI JI gave a challenge during smart hackathon regarding the safety of railway tracks and thats when i started looking for a solution and came up with this idea of Track box, which works on the principle of Seismograph. It notes the motion of the track caused by the movement of the wheel. To be placed near the wheel on the first and last bogey of the train. Broken or damaged tracks will have different vibration / frequency / waves from the normal track. Data to be send digitally with distance and time.
