Metro services in Mumbai - shut for more than six months because of the coronavirus lockdown - will reopen on Monday with the Ghatkopar-Versova Metro One line - which was the only functional line before the nationwide lockdown in March - resuming operations. SOPs (standard operating protocols) for passengers, who will be subjected to thermal screening on entry to stations, will include social distancing - visuals from inside the coaches show stickers that highlight where you can sit or stand - and the use of face masks at all times - whether in trains or on the platform.
