It is these little things that amaze me sooo much! This escalator holds the carts in their place as they are going up and down it. How I do not know, but bravo to the inventor(Cool Idea). No need to panic when you are behind a filled cart, it is not going anywhere.
I choose to avoid taking a picture of the cart on the escalator, because I was pretty certain that who ever would have been pushing the cart would have wondered why I was taking pictures. I knew that would be hard to explain.
