The brother of the alert villager also alerted the authorities about similar fracture just 72 m away from the place of this incident.
The news paper report can be found here.
If this is the case, entire track should be checked for its integrity without waste of time. If the cracks are common as reported, then whether the cracks are appearing only in this section of rail track or all over the country should be found and quality checks of the rails and review of rail specifications should be done immediately. A decision also needs to be taken to replace the tracks at regular intervals, if the cracks do appear after certain length of service.
The alert villager needs appreciation and be recognized in public forum for his service.
