Nowadays there are many accidents occuring due to damage, departing of tracks.especially in summer its happening due to high heat. The tracks getting bulged and very less tracks are bearing the heat. Due to this bulging tracks may depart and trains may undergo accidents and collisions. So we have decided to use waves to pass through the tracks with which we could find the damage as the waves signal may be lost whenever there is a damage on certain track. So it is a new technology that we are trying to build up. We may eliminate the accidents and collisions. Coming to waves we may use laser waves for this purpose. We may also use sensors (quartz metal) to produce electricity with same technology so its multi useful.
