The article says one escalator will remain as normal, so if there are
two up escalators, you would have three of the four sides for standing,
while still leaving one side free for walking.

That'll never work. Maybe if they made the walking side red-hot.

As the article says, they'd use a colour code on the steps and moving
armrest to indicate a non-walking up escalator. But it would take a lot of
public education to get it to work.

Of course, when escalators are not busy, people also walk up the right
hand side.
