Escalators in MRT stations should not be functioning like staircases. The main issue is that those doing so are overburdening the escalators.
Also, commuters who are right-handed will then be able to hold on to the railings on the right without having to move to the left to make way for those wishing to “walk” on the escalators.
Disallowing people from walking on the escalators will lead to normal usage of the machines, which would help in reducing the frequency of breakdowns.
