Safety stickers are appearing on platforms at busy Underground stations following complaints of dangerous overcrowding. Tube bosses were criticized earlier this week after passengers were unable to practice social distancing during the rush hour. Cuts to the timetable caused by staff shortages led to alarming scenes at North Acton station, West London, where commuters were forced to change trains and waiting on crowded platforms. The new blue stickers are spaced two meters apart to allow passengers to stand a safe distance from each other. Frequent station announcements are being made to advise passengers to comply with the social distancing rule. Tube trains are now disinfected every day.
