Could it be the Nebraska Agriculture Department’s Waltonian fish car? THE FISH CARS •Nebraskaland Magazine (not pictured there but mentioned). It does have the look of a work car, especially since it doesn’t have an open platform on the end, and the windows are kind of minimal. The trucks are pretty massive even for an interurban, so it’s definitely a steam railroad car.

A quick search for photos finds them. They have the chines ( Intermediate angles away from the peak OR wall) on the roof, forming a flat surface at an angle to the outside view… Looks like racing stripe paint in some photos, but its an angled surface…
Given the OP’s railway car does have the label “Agriculture” at the right hand side high up, AND “Walt” something “nian” on the side lower down
Great job, right down to the specific car.
737 body fuselages are delivered to the Boeing Renton plant by railcar, part of the tracks travel down the middle of streets near downtown. Google Maps
I saw some of those go by me I think in Montana; was very weird to see a train hauling airplane fuselages!
