I just love this. Almost as much as I like seeing the engine, the young fellow who did it is almost as interesting. He seems a little eccentric, but that seems normal for people who are hyper-focused on a single thing. If I could take the perfect trip, it would be to see this kind of stuff. Not in a museum, but actually working in its original environment. Watch through the whole video, and you will get a ton of history about steam in general, and about how this one survived all these years.
