Theme parks, specifically Disney, are a really interesting look at how “silly kids media” absolutely contributes to revisionism and forgetting the past. If you spend much time looking at 60s-80s era attractions there’s a lot of glaring sanitization of the Antebellum South and it’s interesting to see what people recognize as a problem and what they wave off. It’s a much more familiar and obvious issue vs industrial history and especially trains, which most won’t see the problems with unless they actually work in it.
It’s a bit tangential but I mean, Omnimovers are a chain of vehicles on a track and are objectively trains imo. Also very relevant to Collis’s concept in Train Cabaret. In an interesting twist, the mini new-build steam engines made for parks of this era by Crown Metal Products WERE deliberately far easier to run and maintain and almost free of visible smoke when converted to run on propane. It’s likely a contributor to the sanitization of steam engines but it’s also something just done as a practical choice at parks, which is fascinating in its own right. It’s notable that Disney was a major contributor to amusement parks replacing aspirational but present and real trains with cute sanitized images of Old Western steam engines and sci-fi alternatives to conventional electric trains (which is sad because there’s so many weird historic electric trains even MORE alien to modern audiences begging to be made into rides)
