Dovetail, I think I have the next best idea for an American passenger service route: The Washington D.C. Metro! The sheer size of the entire system is impressive by itself, but the architecture of the underground stations is unmatched! It’s gorgeous! Notice how there are no overhead lights inside the stations. It’s all lit by reflections off of the walls and ceilings. So cool! I highly suggest this route be considered for the future! Keep up the great work, Dovetail!
