As I recall, the two cars behind the GN U33C were streamlined combination cars from the Ringling Bros. Barnum & Bailey circus set. Nothing terribly new in that. One loop on the test layout is S gauge Fastrack.
No SD70ACe's were to be seen during the open house. In fact very little newer Flyer was to be seen during the open house. Remember that Canfield is a repair center and not devoted to new product development.
