Puzzles based on moving escalators have been around for, possibly, as long as escalators themselves. It would thus be a stretch to describe what follows as an original puzzle, but I have tinkered with a couple of existing forms of such puzzles and merged them into one using my own variables.
To solve this, what you need to bear in mind is that in a moving escalator, new steps appear one by one from one end, while old steps simultaneously disappear into the other end.
