Hi, I'm wondering about SD50 UP . I heard about an article talking about the unit made by DTM. But the only ones I could find Is the Conrail one and Rio Grade. Is it on steam or somewhere? Heres the link i found about it : https://www.justtrains.net/articles/six-us-loco-collections-from-trains-and-drivers-on-sale There are two UP Versions the bottom one is what I want.
