Northern Railway has achieved a major milestone on the Udhampur Srinagar Baramulla Rail Link National Project (USBRL) with the break-through of an important Tunnel T-13.
The daylighting of the single section of eight kms main tunnel was done making it completely through from its south portal. The line and level of the tunnel has been precisely achieved in the break-through.
On August 2, the Escape tunnel of T-13 was made through. The total length of the T-13 Main tunnel is 9.26 kms (combined length), having single section length of 8.0 kms and a wider section length of 1.2 kms.
The total length of tunnel made through at present is 9.1 kms with balance length of 150 m in the wider section targeted for completion shortly, S.P. Mahi, CAO/USBRL said.
The wider sections of the tunnel have been designed to accommodate station yards of Dugga and Sawlakot on either portal ends. The tunnel shall be paved with state-of-the-art Ballast less track keeping in view the low maintenance aspects and good riding comfort.
