Printed them out - thanks.
1.  The overhead shot answers the question of where did the platforms added later went (to the left of the large canopy). They will be made as separate items so can be added or not added depending on the era in which folks model the station.
2.  Other shots answer the question of what the left end looked like.
3.  One shot gives me a slight idea as to what the rear looks like but I still need more info.
4.  One shot shows the concourse so that's solved.
Still need:
1.  Shot(s) of the right end.
2.  Shot(s) showing the rear (above the concourse).
3.  Shot(s) showing how the large canopy joins with the rear of the building and concourse.
4.  Building dimensions.
5.  How many tracks are under the large canopy? (30 I think). 
As for the Omaha, Kansas City, and Chicago stations - one axe in the middle of the foreheadache inducing project at a time please, lol.
