Overview

• Services on the North–South corridor were halted at 9:05 AM when heavy rain caused water to seep into the tunnel between Central and Chandni Chowk, triggering a safety suspension until 10:58 AM.
• Truncated operations ran between Maidan and Kavi Subhash and between Girish Park and Dakshineswar during the water ingress disruption.
• Shortly after full restoration, a suicide attempt at Belgachia station prompted a second suspension at 11:20 AM, with normal service resuming by 12:28 PM.
• Metro engineers disconnected power, pumped out water and sealed identified ingress points during emergency repairs to safeguard the electrified third rail.
• Metro Railway has announced a detailed investigation into tunnel flooding causes and plans structural and drainage upgrades to prevent future monsoon-related interruptions.
