The world's tallest rail bridge is on France's Tarn River and its tallest pillar rises 340 meters while the actual height at which trains run on the bridge is 300 meters.
Observing that wind speed at the height of 359 meters may go up to 266 km/h, the engineers have decided not to allow trains crossing the Chenab Bridge if the wind velocity is more than 90 km/h.
The railways has designed the signaling system at the bridge in such a manner that it shows the stop light automatically when wind speed is more than 90 km/h.
Considering the inaccessible terrain of the Himalayan mountains the bridge will get a special coat of paint with a life span of around 35 years to protect it from the tough weather.
