Empty rakes were run on the Pamban rail bridge to check the stability and among other issues, railway officials said here on Monday.
Last week, when the Rameswaram-Chennai Express train crossed the bridge, some technical snag was spotted from the sensor recordings installed on the bridge. As a precautionary measure, the railways announced that all trains would leave from Mandapam railway station instead of Rameswaram station until further orders.
Senior officials and bridge engineering experts from Chennai reached the site and examined the snag two days ago.
The IIT Madras, which had installed the sensors, visited the site and decided to run empty rakes to check for fitness of the bridge, officials said.
Meanwhile, railway officials here said that till December 28, the trains would be operated from Mandapam railway station only.
