Caoimhín Kevin Bunker posted three images with the comment: "Here's just one of those perfectly posed roundhouse photographs:  Union Pacific's Kansas Division at Armstrong, KS., c.1870s.  We see four beautiful Baldwin 4-4-0s and four handsome Rogers 4-4-0s, the eldest and smallest of which (making the most stack exhaust) had been downgraded to a switch engine and fitted with pilot footboards.  The engine crews also posing were justifiably proud.  Southern Methodist University Libraries - digital collections (online)"

Guillermo Bas: Not all the engines shown were 4-4-0s, KP 80 (third from the left) was an 0-6-0 switcher, Baldwin 2326 of 1870. She survived until 1916 as Shop Goat Cheyenne.

The Union Pacific roundhouse at Armstrong, Kansas (ca 1870s), showing off its handsome engines...
Tom Hamilton: I assume that this is Armstrong yard in Kansas City, KS.
Dana T. Parker: Yes. Armstrong used to be a separate community, but was absorbed by Kansas City.

The Kansas Pacific started life as the "Union Pacific Railway Eastern Division" in hopes of siphoning off some of the congressional grant money and land offered to builders of a transcontinental RR. Here's one of the Rogers locomotives fresh from the factory, according to the Rogers order specs.

Wrong "Union Pacific." Kansas Pacific Rwy started out corporate life as the Union Pacific Rwy. Eastern Division in 1863, but had no relation to the Union Pacific RR starting in Omaha. Started laying track in Kansas City that same year, changed name to Kansas Pacific in 1869, and reached Denver in 1870. The photo of the roundhouse in Armstrong, KS, was taken in 1873. Here's one of their early engines.

I've always really liked this picture. I have this smaller non-cropped version that shows the original photograph I.D. plate.

This is how I learned about the Armourdale Yard.

Terry Hinds: Flood of 1951. The Missouri River caused the Kaw river to back up. Heavy rains in the region caused bad flooding.
