The excavation work of tunnel-12, which was posing a major challenge for the completion of the Jiribam-Imphal railway line, has been successfully completed, the Northeast Frontier Railway (Construction) said on Wednesday. It said the remaining small tunnels will be completed by March.

The tunnel-12, covering a total length of 10.275 km with a parallel safety tunnel of 8.30 km on the new Jiribam-Imphal railway line, is the longest tunnel of the Northeast Frontier Railway.

NF Railway chief engineer (NF-7) Vikas Gupta told mediapersons on Wednesday that tunnel-12 passes through the most complex geological strata and the project cannot be completed without the completion of this tunnel.

“The railway is working 24X7 for the completion of work while facing all the challenges of heavy rainfall and other hindrances,” he said.

The tunnel-12, connecting the hills to the Imphal valley, is critical for the completion of the Tupul-Imphal section, the chief engineer said.

“The ongoing tunnel construction is being accomplished by cutting through fragile and soil type strata. The attendant challenges are being tackled on a daily basis through strict 3D monitoring and proactive application of desired tunnel support systems in accordance with the New Austrian Tunnelling Method (NATM),” he added.

Pointing out that NF Railway (Construction) has been consistently executing infrastructure marvels in the most challenging area of North-eastern states, he said, “The railway has taken up tunnelling work in a big way with successful completion of high altitude and mountainous tunnels in Jiribam-Imphal New BG Line Project”.

Saying that the remaining small tunnels will be completed by March, he thanked the state government and all officials for providing necessary support for achieving the critical milestone.
