This photo gives you some idea of the number of trains sitting in the Chicago Amtrak Yard. Look carefully and you can see Amfleet cars, Heritage Cars, Superliner Cars, and even Viewliner Cars!
The photos in this slide show were taken in the mid-1990's by Steve Grande on his Amtrak travels throughout the nation. The size of the photos is purposely smaller as disk space was expensive and download speeds were slower at that time.
