India’s Sets a Milestone; Finishes the Project of First Underwater Rail Tunnel Ahead of Schedule

“A GAINT tunnel boring machine ‘RACHNA’ was deployed to dig the underwater tunnel of length 502 meters in the river.”

India is used to of delayed projects. Indian Railway may have established a record in delaying trains and projects. Recently KMRCL have broken all the stereotyping to set a milestone for finishing a project ahead time. It was 16.6 km long in which more than 10 km was underground. 502 meters of that underground tunnel was underwater. The project connects Howrah to the west and Salt Lake to the east.

It was one of the most difficult and critical projects. Hats off to our dedicated team members of Afcons Transtonnelstroy and KMRCL (Kolkata Metro Railway Corporation Ltd) who finished the project 50 days ahead of time. It took only one month and six days to finish the project.

Unnamed senior official of KMRCL generously gave “The entire credit for completion of the work much before scheduled deadline to the 250 odd engineers, technicians and workers, who have worked day and night to complete the task. On an average they have dug 35 to 40 meters every day.

By December 2019 the entire project of 12 stations in which six of them are underground will be fully operational.

“Considering the pace at which we completed the most difficult task of creating the underwater tunnel, we hope to meet the deadline of final commissioning,” the KMRCL official said.

The total project cost is around Rs 5,000 crores. Since the beginning, the project was held up several times mainly due to land allocation, slum relocation and route alignment problems among others.

The project was originally slated to be completed by 2012. It was first postponed to 2015 and finally to December 2019.
