A canopy is coming in 2018.
These escalators are exposed to harsh elements that they weren't designed for. That's why we're covering them with a glass canopy. It will provide shelter for the escalators -- and more importantly -- for you.

[Note that it's already 2019 but the sign is saying the canopy will be in place in 2018.]
