Longest Electrified Railway Tunnel

The South Central Zone of Indian Railways has commissioned the longest electrified railway tunnel in the country.

The construction of the 6.6km-long tunnel took 43 months to complete.
The electrified railway tunnel is situated between Cherlopalli and Rapuru stations as part of the Obulavaripalli-Venkatachalam railway line.
The tunnel is expected to facilitate freight movement in the region.
It will reduce the distance between Krishnapatnam Port and hinterland areas by nearly 60km.
Authorities developed the tunnel in the shape of ‘Horse Shoe’ employing the New Australian Tunneling Method (NATM).
It features ballastless track with bi-block sleepers and Vaslo fittings.
LED lighting is provided every 10m in the tunnel.
Two traction power supply substations are located near Cherlopalli and Adurupalli.
