A tag of a tailoring shop helped the Government Railway Police (GRP) trace the family of a 57-year-old man who died of natural causes on a local train in Maharashtra's Thane district last month, an official said on Monday.

A passenger, who had boarded a local train in Chhatrapati Shivaji Terminus, died during the journey on April 23, senior inspector Archana Dusana of Dombivili GRP said.
