Is the Shinkansen electric or diesel?

Okay, here's a more personal and human take on that Shinkansen info, like I was chatting about it with a friend:

"So, is the Shinkansen electric or diesel? Well, get this – it's totally electric! Isn't that just amazing? I mean, you think about something so ridiculously fast and powerful, and you just assume it's gotta be guzzling diesel fuel, right? But nope!

It really hits you when you think about it. Two hundred and twenty-five million people a year are zipping around Japan on that thing! And I remember reading somewhere that the Tokyo-Kyoto trip used to take like, six hours? Now it's just a two-hour blur! Can you imagine going from those old steam trains to this electric speed demon? Must have felt like stepping into the future!

And those engines! Did you know there are like, 56 small electric engines working together to power the whole thing? Fifty-six! It's just…mind-boggling how they made that work. It's that kind of ingenuity, that kind of progress, you know? It really makes you feel like, yeah, maybe things are going to be okay after all, right?"
