Jason's hoping for the "matched set" - Coach 3 and 2/9, and a replica of the baggage/mail/express car 1. Put a bathroom in express car for longer-distance trips.
Another replicated pair of 2 and 3 makes sense.
Eventually we should build our own parlor car. Why? A) save the Rangeley for special/historical events, and B) people want a special/premium experience. And, C) eventually the Rangeley will go back to Portland.
