Earlier this year, the Robbins crew and contractor SAM India celebrated the site acceptance test for the first of two 6.65m diameter EPB TBM at Agra Metro. The machine began boring a 1.3km long tunnel in soft soils, for Uttar Pradesh Metro Rail Corporation.

With the first TBM well into tunnelling, a second 6.65m Robbins EPB underwent site acceptance in April to bore a parallel 1.3km long tunnel in soft soils. The crew gathered for a ceremony before sending the TBM on its way.

Then in the same month, the first machine made an intermediate breakthrough into a station site, completing the Jama Masjid to Agra Fort stretch of the metro. The machine bored a total of 345m in sand and clay and broke through to a celebration by the crew and project teams.

New Delhi Metro

On February 27, 2023, the first of two 6.65m diameter EPB for the Delhi Metro (owner is Delhi Metro Rail Corporation) was completed in the Robbins Gurgaon, India facility. The mixed ground machine will bore a 3km long tunnel through rock with some gravel, sand, silt and clay for contractor Afcons Infrastructure.

A second machine factory acceptance followed in April 2023 and both machines are scheduled to launch on parallel tunnels this summer.
