A pair of tunnel boring machines, S97 and S98, arrived at Chennai Port to begin work on the 118.9 km Chennai Metro Phase 2 line.
Tata Projects Ltd. will use two more tunnel boring machines to construct twin tunnels in the core city area as CMRL prepares to begin tunnelling in October.
The two 6.61m TBM machines manufactured by Terratec in China will be used to build approximately 9 km of twin tunnels (a total of 18 km) on Line-3's Venugopal Nagar - Kellys section.
"Two tunnel boring machines have arrived at the Chennai Port. We are waiting for the customs clearance, which will probably take two or three days. The machines will be shifted from the port to Madhavaram," said L Girirajan, Public Relations Officer, Chennai Metro Rail Limited (CMRL), reported Economic Times.
The TBM launched at Madhavaram may take months to reach Kellys, and the length of time would primarily rely on the geological conditions.
Around 26.7 km of Corridor 3's 45.81 km stretch from Madhavaram to SIPCOT and 10 km of Corridor 4, a 26-kilometre route connecting Light House and Poonamallee, will be underground.
Another 5.8 km underground section of Corridor 5 connects Madhavaram and Shollinganallur, which spans 47 km.
The phase II project will require 23 TBMs, and the additional equipment is expected to arrive shortly.

Introducing ElectionsHQ + 50 Ground Reports Project
The 2024 elections might seem easy to guess, but there are some important questions that shouldn't be missed.
Do freebies still sway voters? Do people prioritise infrastructure when voting? How will Punjab vote?
The answers to these questions provide great insights into where we, as a country, are headed in the years to come.
Swarajya is starting a project with an aim to do 50 solid ground stories and a smart commentary service on WhatsApp, a one-of-a-kind. We'd love your support during this election season.
