Spotted this on a YT video. I think it was trying to get into a museum.
It was up in Duluth/Superior and I believe you are right about it trying to get to the North Shore Railroad Museum. It was a bit of a squeeze to get through that section on the BNSF.
Pretty cool. “Look Ma! It’s just like on my train set!” (https://largescalecentral.com/externals/tinymce/plugins/emoticons/img/smiley-laughing.gif)
