Being "in the loop" on this project, I can tell you that the route isn't really a recreation, but more so an inspiration of the BNSF Cuba Subdivision from STL to Cuba. Lewiston obviously representing STL, and on the opposite end of the route, the town of Pamona is inspired by Cuba. I personally don't know how far they are willing to go in Lewiston, in terms of what to recreate/include, but what they have so far is impressively accurate.
