The new safety notices posted in every metro station in the city tell you to stand still.
The notice also warns people against playing, leaning and facing the wrong way, as well as carrying heavy goods or trolleys on escalators.
While standing on the right and walking on the left has been the norm, the city has changed this etiquette to "no walking" for the safety of commuters and the proper functioning of escalators.
According to experts, standing only on the right side of the escalator causes uneven wear on the mechanism because of the uneven load. Wear and tear on the right side is significantly more than on the left, resulting in a slight tilt of the escalator, which cannot be fixed through regular maintenance.
