Railway extension in NE a challenge for engineers

Agartala: The Northeast Frontier Railway (NFR) has to confront many unique challenges in laying tracks in the mountainous northeastern region due to its topography and the danger of natural calamities, a top official has said.
Commissioner of Railway Safety (CRS) Shailesh Kumar Pathak sadi that the NFR gets to work at optimum pace for only four to five months a year as the region witnesses intense rain from March to end-October with the actual monsoon running from June to September.
“As the Himalayan region, specially the northeastern states, are siltation- and landslide-prone areas, the railways have to take additional measures to deal the natural adversities. A lesser working period makes the task more challenging for railway engineers and others,” Pathak said.
He said the per-kilometre cost of laying single-line tracks in the mainland states is Rs 7 crore and for double line tracks Rs 10 crore. “These costs are much higher in the northeastern region due to terrain, marshy land and various other hostile factors.” The CRS was in Tripura for inspecting the newly-laid 9.26 km Udaipur-Garjee section of the 114-km-long track that links Agartala with Sabroom in southern Tripura.
With Sabroom just 75 km from the Chittagong seaport in southern Bangladesh, the Rs 1,150 crore project, to be completed by 2019, will enable the ferrying of men and material from and to the landlocked northeastern states.
An NFR engineer said that due to the large number of rivulets and small rivers, manysmall, medium and big bridges, besides many tunnels, have to be built in the northeastern region.
He noted in this context that India’s longest 11.55 km rail tunnel is now under construction as part of the 111-km-long Jiribam-Tupul-Imphal line that ends in the Manipur capital. (IANS)
