It definitely looks like a roundhouse or a two or three-stall engine house not unlike what Karl describes for the KCCS at Olathe: Imagineered: KCCS Eng Hse, Olathe, KS The "cars" then are presumably the backside of coal tenders: rather diminutive ones, but quite appropriate for the era. Insofar as the location, anyone's guess is as good as mine. If the user who provided the photo lives anywhere near an old Frisco or subsidiary engine/shop facility and received the photo from family or friends, then their locale is probably the most reasonable, I'd think. I always enjoy photos from an era where a good roundhouse man, boilermaker or general laborer wore a vest and a good, snappy hat. Best Regards,
Not much to go on... The tender, which is in the right stall still has link and pin couplers which would date the image before the US Safety Appliance Act of 1893.
I was looking at the Gage, the rail almost looks like broad Gage, wonder if that was before the Gage was standardized.
FWIW: It's my understanding that an extensions were granted and the "drop dead" date for the demise of link n' pin in interchange service was extended to 1899. Interesting photo. Doubt we'll ever know more about it.
