South Central Railway commissiones longest electrified tunnel in Indian Railways

The South Central Railway (SCR) has recently commissioned the longest electrified tunnel of 6.6 km built at a total cost of Rs 460 crore between Cherlopalli and Rapuru stations. The tunnel is part of the 113-km new railway line completed recently between Obulavaripalli– Venkatachalam – Krishnapatnam Port. The electrified tunnel is constructed in the shape of ‘Horse Shoe’ on New Australian Tunnelling Method. The height of the tunnel (rail level to roof) is 6.5 metres and the minimum height of the contact wire is maintained at 5.2 metres. The new line would facilitate direct and viable connectivity between South Coast and West Coast Railway and improve freight revenue of the zone.
