Bowbazar tunnel gets tech shield, seepage checks in Metro’s subsidence-hit zone

Vibration-mitigating track cushions, laser-based monitoring for subsidence, and grouting teams on standby — East-West Metro’s Bowbazar stretch is equipped with a range of protective measures to prevent further trouble in the once-unstable zone, officials said.

The 16.6km corridor from Howrah Maidan to Sector V has faced repeated setbacks in Bowbazar due to soil subsidence.
