My hobby
I like to get up at 6am and go out there and work on the trains, getting them ready for a hard day's work. They're not toys. That particular engine that I'm running weighs 3,000 pounds, and burns coal. Operating pressure is 150 psi, and can pull around 12,000 pounds. Let's see your go kart do that.
Yeah, yeah, i know, I'm boring. Get over it.
