Overview
- Central Railway crews spotted a wire hanging from the overhead equipment near km 31/146 between Mulund and Thane at about 9:23 am on Monday and granted an OHE block at 10:00 am to remove it safely.
- Technicians disconnected electric supply under the authorized block and worked on repairs, which left Down slow/main line services on the Kurla–Kalyan section running behind schedule.
- A smoke event in the Kanjurmarg relay room occurred during the same morning and was cited by DRM Mumbai as an additional cause of signalling delays and train bunching.
- Commuters faced packed coaches and delays reported between roughly 15 and 45 minutes, with some passengers seen walking on tracks between Mulund and Nahur as services recovered.
- Central Railway posted updates and an apology on social media and said investigations into the nature of the hanging wire and the relay-room smoke will proceed after restoration, a development that could prompt closer scrutiny of recent reliability problems on the line.
