No one has yet commented on or asked - what UP BB route is most interesting to you? Before ordering my VLBB, I did a little research of all available road numbers and routes and found the Cheyenne route to be historically quite interesting so I decided on that road number. Plus I used to date a very beautiful girl named Cheyenne. Consider this, consider what region you are modeling and consider that a road number importance is related in context to your modeling world.
