The following Table depicts the short historical notes on Train service to Rameswaram island

 Train  service started from Madurai – Mandapam
1906
Railway Tracks laid between Pamban and Rameswaram
1908
Train service started between Pamban and Rameswaram
1911
The cantilever Rail bridge across the sea was commenced
1914
The pamban Rail bridge has been completed and train service started
Until 1988 Pamban rail bridge is the only connection path between Rameswaram and the main land of India.
This bridge starts its service of connecting Rameswaram island from the date of February 24, 1914. It is a cantilever bridge(In this bridge two cantilever arms fitted in the piers extending from either  sides and  meeting at the center without supports, this kind of structural design is termed as cantilever structure).
The bridge spans a length of 6776 feet (2.065 meters) and has 143 piers. There is a double leaf bascule  in the center of this bridge. This bascule section opens up and let the ships and boats to cross the pamban bridge over the sea.Based on the records averagely there are 10 to 15 large boats or ships (coast guard boats, cargo ships, container ships etc.,) pass beneath this bridge every month.. The bascule was designed by “Scherzer” a German engineer, the bascule part of the bridge is called as “Scherzer rolling type lift span” and have the length of 220 feet and weight of 200 tonnes (each leaf weighs 100 tonnes separately). Till datethese heavy weight leaves are lifted manually by workers operating levers on either side.
The  environment where The Pamban rail bridge stands is said as worlds second most corrosive environment and also this region is a  Cyclone prone and high velocity wind zone.
Cyclone Attack:
On December 23, 1964 A Super cyclonic storm struck the pamban bridge with the velocity of 240 Km/Hour after  swept off the entire dhanuskodi and  upturned the.  Pamban-Dhanuskodi passenger Train with 150 passengers.
Part of the Pamban  Railway bridge was shattered and broken  because of the  catastrophe.

By let everybody in amazement , The bridge was renovated and restored again in just 46 days under the leadership of I.E.S officer E.sreedharan renowned as Metro man.
For his quick heel action to the pamban bridge he was honoured by  Railway minister Award by that year.
The Indian Railway upgraded this bridge to broad gauge  in august 12,2007.
