Bhubaneswar: The Khurda Road-Balangir rail line project has achieved a historic milestone with the successful breakthrough of Tunnel T2 between Buguda and Daspalla in Nayagarh district, the East Coast Railway (ECoR) informed on Sunday.
It was achieved on May 30 and marked the completion of excavation work across all seven planned tunnels, using New Austrian Tunneling Method (NATM).
“Tunnel T2 is the second longest tunnel in Nayagarh district, covering 1,775 metres with 2-degree curve, and a significant part of the project. It was constructed using advanced technology and tunneling methods to overcome the challenging Eastern Ghats terrain, setting a new benchmark in infrastructure execution for Indian Railways,” it further stated.
With the completion of T2, the breakthrough of all seven tunnels in the 75-km stretch between Daspalla and Purunakatak has been achieved, it added.
