Delhi Metro Rail Corporation Spokesperson Anuj Dayal said, “MSS will be used at locations within 25 m. of the horizontal distance of the tunnel and within 15 m. of the top of the tunnel.” The reason for doing this to bring down the vibrations & disturbance from trains running on these tracks, he added.
