Maligaon: The Northeast Frontier Railway (NFR) has completed the concrete lining of Tunnel No 14 of the Sivok-Rangpo railway project on May 15, an official release said on Tuesday.
“The completion of the final concrete lining is a marvellous achievement by the Engineers involved in this project,” said NFR Chief Public Relations Officer (CPRO) Sabyasachi De.
In March 2023, Minister of Railways Ashwini Vaishnaw inspected the tunnel and appreciated the work.

Sikkim will be connected via railways for the first time upon the completion of the Sivok-Rangpo Railway project which is targeted to be completed by 2024.
The completion of the railway project will enhance the standard of socio-economic status of the state.
As per the official release, the New Austrian Tunnelling Method (NATM) has been adopted for the completion of the tunnel through challenging and vulnerable groundmass with the supervision of well-experienced engineers from India along with highly experienced foreign engineers in this project.
“The track linking works is going to start through this tunnel very soon. The Rangpo station situated just after Tunnel No T-14 is also under construction and on completion will be a commercial and tourism hub for the state of Sikkim,” the release further added.
“This tunnel is the gateway of the railway network to the state of Sikkim. The tunnel is about 1977 m long and is situated in the Rangpo Sub-Division of District Pakyong, Sikkim. It is located in between Kumrek and Khanikhola in East Sikkim region and traverses through challenging geological conditions of the Lesser Himalaya,” the NFR CPRO Sabyasachi De said.
