The main track of the old MoPac line run about two blocks from my house. The Amtrak that runs from KC to STL uses that line. I've seen steam trains that have visited KC use that track before. This time, out of Union Station, the train will follow the UP tracks on the south side of the Missouri River, going to Buckner then on to Lexington in Lafayette County. The train tracks bump up right next to the river just to the West of Lexington. That would be a cool place to see the train rolling. Too bad it's on a Monday or I'd go check that out.

Its the last of the UP 800s and is a 4-8-4 Northern. And the only steam locomotive never to be pulled off a major American Railroad roster... I've baby sat it at night,many times when they would run her down from Cheyenne to Aksarben for September fest.... I've road in the cab several times from Omaha to Columbus and back. Unfortunately I've never run it.
