I don't get to see their locos here in Florida, but I understand from the interwebs that they have "heritage" units on the road to commemorate the lines that are part of the U.P.

As an aside, I modeled the CB&Q in my younger years. The Burlington Route merged with other railroads to form Burlington Northern (and it is now Burlington Northern/Santa Fe) 40 years ago. A couple weeks ago I spotted two box cars that still had faded Northern Pacific markings (one of the merged railroads), but I did not have a camera handy.
