What are trains mostly used for?

You know, you ever wonder what trains really do? I mean, yeah, you see them sometimes, maybe stuck at a crossing, but what's their main gig? Turns out, it's hauling stuff. Tons of it. Like, mountains of cargo. Cars, clothes... heck, even the wood for your dining room table probably rode the rails. It's kind of crazy, isn't it? We just take it for granted, all this stuff appearing in stores as if by magic, but there's often a train behind it all, chugging away in the background.

And it's not just about brute force moving things either. They're getting pretty high-tech these days, some of these trains. Plus, way better for the environment, less pollution than all those trucks on the highway. Remember that time we were stuck in traffic for, like, ever? Ugh. More trains could definitely help with that mess, right? I read somewhere that they can take a ton of trucks off the road – I wish I could remember exactly how many, but it was impressive! So yeah, trains. They're more important than we think.
