On completion, the 9.02-km tunnel will be the second longest one in India
A 10.7-km railway line, including a 9.02-km tunnel, has been proposed to connect the upcoming Vizhinjam International Multipurpose Deepwater Seaport to the railway network.
The 9.02-km tunnel, mooted by Konkan Railway Corporation Ltd (KRCL) from near the Balaramapuram station on the Kanyakumari-Thiruvananthapuram railway line, will be the second longest railway tunnel of the country on completion.
The KRCL, in its draft Detailed Project Report (DPR) submitted to Vizhinjam International Seaport Limited (VISL) — a special purpose company supervising the execution of the seaport project — has favoured the railway tunnel from Balaramapuram in view of the 35-metre level difference between the port and the highest ground level, undulating terrain, and local population.
