Ever seen a gangman walking along the track holding wrench and hammer in his hand. He's actually inspecting the track all the way looking for any minor issue. Major issues are found by occasional visit by PWI or DE of that particular division on trollies that are pushed by gangmen.
Furthermore patrolling is done by every division's gangmen. In night, you see some people giving torch to coming train. They are in patrolling party. Also railway police is responsible for safety.
Train journey is still the safest as compared to road.
