India's Longest Railway Tunnel Is 11 Km Long & Is Now Open!

The Banihal-Qazigund railway link was inaugurated recently and it's now open for business. The rail-link boasts of India's longest railway tunnel, whooping 11 kilometer long. The tunnel pierces through the Pir Panjal mountain range in Jammu & Kashmir. The tunnel has been in construction for over 7 years and about 1300 workers under guidance of 150 engineers worked effortlessly to build it.

The tunnel has been constructed using New Austrian Tunnelling Methoda aka NATM and it's the first time that this technology has been used to build tunnel of this scale. The tunnel has been constructed by Hindustan Construction Company. The crown of the longest railway tunnel however goes to Japan's Seikan Tunnel which is monstrously, 53.85 Km in length.

The overall cost of the tunnel project is estimated to be Rs. 1700 crore.

Contrats to the entire HCC engineering team that built India's engineering marvel!

    Location in J&K, its length and the known laxity of the railway admin lays the tunnel wide open to security hazards. I fervently hope that adequate infrastructure is in place to protect this great piece of engineering.

    One of my friend(M Tech, IITD) has worked as one of the mining engineer on this project for around 2.5 years. I will check with him, if he can join CE and share his first hand experience that what they have faced in making this a reality.
