Like any other new project, the Mumbai Metro Aqua Line 3 has also been no exception and has been facing teething problems. A few problems that have been persistent in the first week of Aqua Line 3 operations have been train detentions leading to delays, few dysfunctional escalators and commissioning of limited entry/exits at a few stations. Besides other technical reasons, one of the prominent issues causing train detention and delays has been the train doors not opening or remaining open for longer times.
