In history of railways , almost 90% of the accidents happens because of two reasons:
Train comes away from track
Track discontinuity
TRAIN COMES AWAY FROM TRACK
It means that track is not all problems but train moves out of track. This happens because Of lack of concentration of the people who works with track. For example when the nuts and bolts get loosed these sorts of problems will occur, where property loss will happen to both public and railways but not that much as the second case.
TRACK DISCONTINUITY
i) This happens because of terrorism attack, natural disaster. There will be damage to track which causes severe damage to both public and railways which in many cases have led to several deaths.
ü) By keeping such issues in mind, we have come up with an idea to detect the track discontinuity very sooner before the train reaches the accident zone.
