Now having worked at Universal, I can say that the road behind is the most important path between wardrobe, USF, IOA, all of the operations buildings, and one of the team member grills. I find it hard to believe they would or could run a train down the middle of it. If they do though I think the only feasible way would be to have fake windows.. or maybe real windows with a projection system/screens a few feet beyond the windows. Both ideas are pretty problematic though. What would it look like when people are boarding and unboarding?
