The courage and sense of duty of a Railway security guard saved an elderly man from being crushed by a train at Vapi station in Gujarat on Tuesday. The daring act was captured by a CCTV camera at the station. The footage shows several people crossing tracks to go from one platform to the other -- a foolhardy and very common practice across the country. One person is seen struggling to get on the platform, and a Government Railway Police (GRP) guard helps him.
