... Was his name localized to Tomas for Spanish speaking regions... or are you doing a Mandella Effect bit?

Um, no, I've not been to that museum, does sound awesome, but my (nearly 100% certainly also autistic) grandpa had an entire, fully functional landscape / diorama / train track kit, that he spent like two decades slowly building... it was the size of roughly two queen mattresses, end to end.

I also did go to some train museums / exhibits up in the PNW, the cascades, they've kept an old school steam engine working on I think an old rail line for logging, up around snoqualmie, it'll choo-choo you around a nice little relaxing loop.

Like, I am entirely unironically the stereotype of 'loved trains waaaay too much as a kid = autism', and it literally runs in family, hahah!
