That's Why Escalator Stairs Have Grooves

Why do escalators have vertical grooves in them? Haven't you ever noticed that escalator stairs are grooved? Well, they are! But why do these moving stairs look so unlike regular stairs? In fact, those grooves perform an essential role in the operation of the escalator.
First of all, an escalator is a complex mechanism, and the stairs you’re standing on are an integral part of it. Standing on the steps of an escalator is basically the same as standing inside a clock: you’re right in the heart of things. And the most awesome part is that you’re also standing both on the outside and the inside of the escalator at the same time!

I tend to think of riding escalators in terms of how I would drive or walk on the footpath. So, being in Aussie, I'd stand on the left and walk ('overtake') on the right... but it was one of the first adjustments I made as a pedestrian when I travelled to the USA some decades ago, to change sides... but in some places in the USA, it didn't seem to matter... I think, because there's just so many people... and they all seem to be in a mad, tearing hurry all the time...

Fun fact: The escalators shown in the video at 4:52 are actually not the mid-levels escalators. The ones shown here are the walkways connecting the Central and Hong Kong subway stations. The real mid-levels escalators are much longer, sloped and are outdoors. I'm from Hong Kong so I know :)) Proud to be from this fast moving and special city.

When I was a kid, I would walk up the down escalator and down the up escalator at department stores for fun. The employees never said anything when I did it and there would be little to no people riding the escalator, so I didn't have to worry about walking into people going in the other direction.

Here in Australia our shopping centers have Escalators that aren't the stair variety, And the grooves are used to hold the wheels of shopping trolleys. By which I mean that the shopping trolleys have special wheels that slot into the grooves and prevent a trolley from moving until it reaches the end of the run.
