Martin Hansen wrote the followng on November 14, 2021:
In 1947, when the Union Pacific delivered this brute of a 2-8-2 locomotive to the Mt. Hood Railroad at their yards in Hood River, Oregon, the shortline was certain they had solved their motive power shortage once and for all. This beast would certainly be able to haul more tonnage up through the switchback on the way to Dee and then on to Parkdale than the current Baldwin 70-ton 2-8-2 that the Mt. Hood RR had in service.
Before she was put in service her number was shortened to simply "36" and the UP name was painted over and the Mt. Hood Railroad name put in its place. With this all In place it was time to put her to work. That's when the plan came unraveled.
No sooner had the "new" #36 left the yards with her first train when she rolled the rail under her and landed on the ties. This was repaired and she started off again only to repeat the same process all over again. Obviously no one had realized that weight and the long ridged wheel base of the drivers was much more that MtHRR 2-8-2 #1 and clearly more than the light rail of the railroad could handle.
In disgust, the railroad officials realized they had purchased an albatross that they would never be able to put in service. #36 was pushed off on to a siding in Hood River to wait out her days before they called for the scrapper. She would be a constant reminder for the railroad that new motive power purchases in the future would have to take into account the limitations of the track used by the railroad.
