The damaged pictures on the wall have been replaced. They have a matte surface, and you have to really look to see the crackle texture. It doesn't look nearly as nice (the ones on the right side of the hallway are still original so you can see the difference quite readily) but I suspect it's a lot more durable.
In other minutia: The loop around the floor between the glasses station and the spiral stairs has been put back.
Single rider seemed to be the way to go yesterday. The line was nearly empty, and they were taking large chunks of it at once (I'm talking whole rows filled with single riders), while there were backups causing delays at the office and elevator doors. Not sure what that was all about, they are usually efficient about filling carts to the point of making single-rider a veritable crawl.
