Suffocationtion and delay — this is what automatic door-closing in non-AC locals will result in as per the four-day trial held between Churchgate and Virar. Three coaches of a local were fitted with automatic closing-doors and trials were conducted between January 2 and 5 in an experimental move to curb commuters falling from trains.

A report prepared by the railways observed that the closed doors delay the train by a few minutes and cause the carbon dioxide levels to rise due to lack of ventilation. It also noted that the coaches had less illumination.
