Rebuilding the bridge to Rameswaram
The swanky new sea bridge at Pamban glistens in the summer sun. Among the three choices, including a swing bridge and a single-leaf bascule bridge, the vertical lift span best suited the Indian Railways’ requirements of stability and cost-effectiveness. How it works While the old Pamban rail bridge had a Scherzer lift span that would open horizontally, the new bridge has been fitted with a vertical lift span, the first of its kind in the Indian Railways. “Whenever the Madurai-Rameswaram section gets the second line, the new bridge will also get double lines; the sub-structure has a provision for the second line,” a railway engineer said. “Whenever wind velocity goes beyond 58 kmph, the signal for train movement on the bridge would turn red and no train would be allowed to enter the bridge,” the engineer said.
