Be Specific—ship “Union Pacific” A lone horse pretty much ignores an eastbound Union Pacific stack train as it speeds through Pixley, Wyoming, on the railroad’s Pocatello Subdivision on the morning of September 28, 2020. General freight no longer travels in 40-foot boxcars like the one now being used for ranch storage, but a lot of it does get shipped in containers like those passing by on the intermodal in the background.
