SRINAGAR/NEW DELHI: After a successful trial run a few days back, the world’s highest railway bridge, touted as higher than Eiffel Tower, over the Chenab in J&K, will be made operational soon after a few more trial runs, government sources said. Railway Minister Ashwini Vaishnaw said on Sunday that the first run of a track-mounted trolley on the arch bridge was conducted on March 21.
