An Interesting Discolored Ffarquhar Station

[Super]

Updated...continually being amazed at what caused this even colorization I originally thought that the green portions of the station were not affected by this at all. A side by side comparison proved me wrong. I the picture below you see the platforms bench seats of the discolored one and a regular station. The one on left is the affected one and we can see that it too has taken on the light tan like the rest of the station.

So, to me, it looks like the whole station was exposed to something that affected all the plastic but not the stickers. I am baffled at how perfectly  the color is all around the station almost like it was placed in a sealed chamber and something pumped in that changed it.

I still can't logically comprehend how it is perfect.
