It is still necessary to wear masks in the subway but the intervals between arrivals of trains have come back to the days before covid-19. Since Monday all three lines have shortened their intervals, especially in peak times.
B and C lines have now 20 seconds less between arrivals and A line has shortened its intervals by 45 seconds in the morning peak. On all lines trains will arrive to the station in maximum three minutes. Outside of peak times the intervals will be five minutes, weekends and holidays will stay at 7,5 minutes.
