Overview
- The 8:33 AM Titwala–CSMT AC local suffered a loss of auxiliary power that shut down its air conditioning, fans and lights for about 15–16 minutes on Monday, turning a sealed, overcrowded coach into a poorly ventilated space.
- Three passengers complained of breathing difficulties and one commuter, Fahim Ansari, was taken to hospital for oxygen and observation and later discharged the same day.
- Railway staff ran the train with doors open between Mulund and Kurla to improve airflow, then withdrew the rake to the Kurla car shed for inspection and cancelled or replaced subsequent services.
- Central Railway has launched an inquiry to determine why adjacent AC units did not automatically take over and why the onboard technician could not reach reset controls because of crush loads, while retired engineers have proposed fixes such as battery-backed emergency ventilation, cab-based controls, remote diagnostics and additional access panels.
- The incident exposes a wider risk with sealed AC suburban rakes that rely entirely on forced ventilation, highlights gaps such as the lack of an emergency medical room at Mulund, and could prompt engineering changes and stricter operating checks as AC services expand on the network.
