Tunnel Boring Machines

The Elon Musk backed tunneling venture will start full scale hyperloop tests by the end of this year

A section of Kolkata's prestigious East West Metro service - a 16.6-km-long route that includes the country's first underwater train line - met with "unprecedented disaster" after tunnel boring machines hit an aquifer resulting in flooding and cave-ins that forced the evacuation of more than 400 people from the area

For Elon Musk's very difficult year, there's a light at the end of the tunnel. Specifically, it's a 1.14-mile tunnel the inventor and beleaguered CEO of Tesla Motors says is a first step in solving "soul-destroying" urban traffic. In 2016, Musk - already busy running two high-profile companies - founded a firm called the Boring Company to tackle th...

Two top-order tunnel boring machines, nicknamed Rachna and Prerna, are digging India's first ever under-the-river Metro tunnels in Kolkata at full speed. If all goes through, then one could take a Metro ride under the Hooghly river in December 2019.

Bertha, one of the world's largest tunnel boring machines, emerged north of downtown Seattle on Tuesday shrouded in clouds of dust and chunks of falling concrete, completing the most difficult phase of a plan to build a highway under the heart of the city.

Bertha, one of the world's largest boring machines, will cut through a thick concrete wall at midday on Tuesday if all goes according to plan, completing the most difficult phase of building a highway under the heart of downtown Seattle.

Qatar's metro, once completed, will run hundreds of kilometres across ultra-modern Doha, along the coast and into its expanding suburbs.

For the first time in the country, the construction work of two parallel tunnels were completed together at Dabri Mor, on the Janakpuri West to Botanical Garden corridor of Phase III, a DMRC spokesperson said on Tuesday.

An engineer from Romania, working on state-run NHPC's Parbati hydro power project, died on Tuesday while repairing a tunnel boring machine (TBM) at a construction site in Garsa valley of Kullu district, police said in Shimla.
