THE HEROES OF PAMBAN
These are the people who work hard to make the the Legendary Pamban Bridge still Operational. If they are not there, these bridge would have collapsed long before. The atmosphere of this area is very saline(of course it has to be, it is sea) which increases rate of corrosion faster. Hence, they will have to make sure that, not a single place in bridge is rusted. They have to walk 2 km through the sea bridge for making sure that, nothing goes wrong in bridge so that commuters can have safe journey.
That...
more... day, they were going to paint the cantilever part of the bridge and also was doing some maintenance in that section. When train reaches near to their area, they will move out and just as the train passes by, they were back to action.
