I looked at tron's concept art for the outside. I went TOTAL Disney geek freak over a minor detail. Just below the upper left corner, for the train, that's not any of the locomotives on the Walt Disney World Railroad, oh no. It's the Carolwood Pacific Lilly Belle! While it could just be there to represent the railroad, I see it as a hidden tribute to Walt Disney and his Carolwood Pacific Railroad, which we would not have ANY Disney parks had it not existed. For reference, I've included a small snapshot of the train in the art and a photo of Walt's Lilly Belle (not mine).
