UP 844

The photo isn't "vintage", but that locomotive is the genuine article (though I cringe using the word "vintage" , in this manner).
This is the only steam in the US, that was never retired. The UP couldn't seem to be able to resign themselves to the fact that those super powerful steam locomotives that they had developed were obsolete. Thus, they kept a "steam development program" active, and kept 4-8-4 "Northern" numbered 844, on the active roster. When steam excursions became popular, this locomotive became an overnight sensation. UP continues to use this loco, and a newly restored 4-8-8-4 "Big Boy" on their roster, as public relations tools.
I certainly appreciate their efforts, which come at great expense, in keeping these engines serviceable, and operating. This photo was taken on the third occasion that I got to see this beautiful locomotive, newly restored to her original numbering of 844 (it had been renumbered 8444, in deference to a diesel roster, that needed the original number).
I've taken several photos, at this location, which was the site of a one-time flag stop, known as Cobbler, on the UP River Subdivision, just south of Atherton (Eton Junction), Missouri.
