Survivors haunted by deadly Indian train crash as clues emerge.

Survivors of a deadly train crash in India that killed 275 people and injured hundreds are haunted by the trauma. The crash occurred after a signaling failure caused the Coromandel Express to collide with a goods freight train, knocking it off track, and was then hit by a second train coming from the opposite direction on a parallel track. Investigators are recommending an investigation into the crash. Many people are still waiting to identify and collect the bodies of their relatives.
