Central Railway Chief Public Relations Officer (PRO) Dr Swapnil Nila, in an interview with mid-day on Thursday, said that the cause of the Mumbra incident remains a mystery and that the railways have immediately expedited the plan to convert suburban services on the main line to 15-car, boosting the capacity by 25 per cent.

Four persons were killed and nine others injured on Monday morning after falling from an overpacked CSTM-bound local train during peak rush hour between Mumbra and Diva railway stations.

What really happened?
There is no clarity so far. The cause remains a mystery, and we are examining all aspects. A five-member committee has been formed with a mandate to find out exactly what went wrong that made eight people fall at one go.
