During our run to 2023 Seattle, Washington my sister and I traveled along the Columbia River Gorge on our recent trip and the only Union Pacific Equipment I caught on this day was this Maintenance of Way Equipment at The Dalles in Oregon. It was busy picking up ties on the Portland Subdivision, down from The Dalles Dam, on June 20th, 2023, with UP 958200 leading.
From what I can find online Union Pacific took delivery of the RELCO built MofW work train set #958200 in July 2019. The set is made up of special flats/gons and a rebuilt SD-40-2 locomotive (former number unknown). The trailing unit was numbered UP 958201.
