Imphal, February 21 2023:
Northeast Frontier Railway (NFR) has stated that the Jiribam-lmphal new line railway project, which is one of the crucial connectivity projects in the North Eastern region, is in an advanced stage of completion.
In a release, NF Railways chief public relations officer Sabyasachi De informed that works for the new line railway project, among other connectivity projects, is also underway in full swing to connect Imphal, the capital city of Manipur, with the rest of the country.
Jiribam-lmphal new line railway project, which is about 110 km in length, includes multiple tunnels and bridges in tough ter rains.
Out of 52 tunnels, tunnel No 12 is the longest tunnel of the project with a total length 10.275 km including 529 metres RCC Ramp with a parallel safety tunnel of length 8.3 km.
the said tunnel passes through the most complex geological terrain having fragile soil type condition.
Tunnelling work in this stretch is one of the most challenging jobs and NF Railway is putting full effort by working round the clock for completion of work despite all the challenges like heavy rainfall and other logistic hindrances, the officer said.
NF Railways also mentioned that for the first time in its history it has adopted vertical shaft construction technology for the complex tunnelling works.
"Normally this technology is used only in the metro projects.
Considering the complex geological condition of Imphal valley and to reduce the construction time of balance tunnelling stretch, vertical shafts are being constructed.
This will help in expediting the progress of the tunnelling work.
All the tunnelling activities will be done through vertical shaft with the help of gantry crane and other modern machineries," added the PRO.
NF Railways stressed that it has been consistently achieving success in the execution of infrastructure marvels in the most challenging area of NE states.
The Railways has taken up tunnelling work in a big way with successful completion of high altitude and mountainous tunnels in Jiribam-lmphal Project, it maintained.
