Bhopal Metro reaches milestone as TBM Durgavati drills first 10 meters

Underground tunneling gains momentum for the Orange Line as second boring machine prepares for deployment to expedite the 3.39 km stretch.

The Bhopal Metro project achieved a significant technical breakthrough as the Tunnel Boring Machine (TBM), named ‘Durgavati,’ successfully completed the first 10 meters of tunneling for the city's underground section. This development marks the commencement of the subterranean phase of the Orange Line, which aims to connect densely populated areas of the state capital.

According to officials from the Madhya Pradesh Metro Rail Corporation Limited (MPMRCL), the progress includes seven meters of temporary tunneling and 3.3 meters of permanent reinforced structure. Work is now set to accelerate with a second TBM expected to be lowered into the shaft shortly to begin parallel drilling operations.

Deep excavation ensures stability

The TBM was lowered to a depth of 24 meters (approximately 75 feet) near the Red Sea Plaza area on March 30. Engineers stated that operating at such a depth is a strategic choice to minimize surface-level vibrations.

This is particularly crucial as the Metro alignment passes beneath some of the most congested residential and commercial pockets of Old Bhopal. Continuous monitoring systems have been deployed to ensure the structural integrity of buildings above the tunnel path.

Precision engineering in heritage zones

The tunneling process is currently moving from the Pul Patra direction toward the proposed underground stations. This technical feat is a first for Madhya Pradesh, utilizing dual TBMs to navigate complex geological strata.

The 3.39-kilometer-long underground stretch is designed to link critical transit hubs, including the Bhopal Railway Station and the Nadra Bus Stand. This connectivity is expected to significantly decongest the city's main arterial roads once operational.

Strategic underground station design

The project includes the construction of two major underground stations at Bhopal Railway Station and Nadra Bus Stand. Each station will span approximately 180 meters in length to accommodate high passenger footfall.

Official blueprints reveal a three-tier station structure. The ground level will house entry-exit points and commercial kiosks, while the concourse level will feature automated fare collection (AFC) gates. The lowermost platform level will be equipped with modern safety features and digital displays.

Timeline for corridor completion

The underground section is part of the second phase of the Orange Line, which extends from Subhash Nagar to Karond. While the 6-km priority corridor from AIIMS to Subhash Nagar is already seeing active progress, the underground link remains the most challenging segment.

Metro authorities indicated that the entire underground construction, including the 143-meter transition ramp near Bada Bagh where the tracks return to the surface, is slated for completion within the next 24 months.

Collaborative administrative support

The rapid pace of the Bhopal Metro Update is being attributed to the seamless coordination between various government bodies. The Bhopal Municipal Corporation, PWD, and the local police have assisted in traffic diversions and utility shifting.

Public interest in the project remains high, as the Metro promises to slash travel time across the city’s North-South corridor. Sources indicated that the arrival of the second TBM will effectively double the daily drilling rate.

Future connectivity outlook

As Bhopal transitions into a metro-connected city, the integration of the underground stretch is viewed as the final piece of the urban transport puzzle. The project aligns with broader National and International News trends of shifting toward sustainable mass transit.

With the successful initial run of TBM Durgavati, the MPMRCL is confident of meeting its 2028 operational targets. Residents can expect further Government Updates as the machine progresses toward the heart of the city’s commercial district.
