This is a different work platform area. Chicago is in the background. On the left is a Superliner train and on the right is a train with some Amfleet Cars and a Viewliner Car.
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.
