The first picture is the queue, the picture is taken from the wooden emergency exit and shows what used to be the wooden fence and the painted concrete wall you used to walk straight towards to when passing over the bridge. Good to see that they finally realised they forgot to theme that area, took them only 7.5 years.
The last picture is more difficult, the plan in the background shows buildings, which makes the position quite obvious. But it doesn’t make much sense to me, as the Rockwall shown would be in a place where a perfectly fine (and themed) wall already is. As the image also shows some stairs, this might hint towards the Raik area, but that makes little sense to me as well.
Ideally, they would finally use the viewing area that was obviously planned in the beginning, but not used for some reason (I guess some permits regarding fire safety or something along those lines). But that one is in a different place than that plan hints to.
Anyway, I am glad to see that Klugheim gets some more attention. I really enjoy the area, but once in the queue for Taron, I felt that the theming level dropped significantly. The update to the Chiapas wall will improve this quite a bit.
