How are the escalator stairs attached?
There are clips at the bottom and at the top it's gravity then a plate. The clips are http://www.bricklink.com/catalogItem.asp?P=6019 and http://www.bricklink.com/catalogItem.asp?P=60478
This might help as well. http://4.bp.blogspot.com/_1OoLlXKzxa8/S22jbe4vPtI/AAAAAAAABBo/PMNUrHNvyQQ/s1600-h/pic+29.jpg
Does that revolving door actually... well, revolve?
I meant how are the stairs (the plates) on the escalator itself actually attached. The picture you posted doesn't show that step.
The "plates" on the stairs are double cheese slopes, not actual plates! It looks like the cheese slopes and grille pieces are both placed on a single long black plate.
