Hi,

If it helps we have a fairly good idea where to look in the station. The second clue (http://twitpic.com/2osynt) shows the windows in the station. The sign appears to be underneath the blue and red windows. Here is a picture of the station: http://www.flickr.com/photos/peterbach/4794523040/sizes/o/in/photostream/ You can see in the far right of this photo the blue and red windows, so we think it may be under here. Also, the first clue is here: http://www.theoryland.com/images/FinalClueCrop1.jpg. So we are looking for a pink sign with white lettering, underneath blue windows on the right and red windows on the left. Also there is a camera there as well. Hope this helps.

Thanks!
