On June 2, Monjumoni Patra, 42, boarded the Chennai-bound Coromandel Express at Balasore in Odisha. She was travelling on an unreserved ticket to Cuttack to get her medical reports from a clinic. She had barely been on the train for a few minutes when it collided with a stationary goods train in the Bahanaga Bazar area of Balasore. The collision caused the derailment of 21 coaches. Three of them hit the last two coaches of the incoming Bengaluru–Howrah Express. The rest of the train moved on with its passengers to its intended location.
