Kesari Sharma explores the interiors of the service tunnel. The orange pipes are protection for the OFC (optical fibre cable) that are being laid along the railway lines. One of the vandalized Sodium vapour lamp can be seen on the left of Kesaris head. The igniter in the next broken lamp was trying to light a nonexistent lamp, producing dramatic sparks that could be seen and heard from the mouth of this tunnel.
