These are actually miniature trains... yet, they are EXTREMELY real! This is one SERIOUS hobby for some. There's a park near here with tracks running throughout. These train hobbiests (I know that's not spelled correctly if it's even a real word ) come twice a year. There's a train yard where they work on them with raised tracks to preserve their backs. There's a tunnel, and a bridge... and some of them have cars with benches you can ride on. I really love to go see them every year. The detail just amazes me. And as you can see from the last pic... the adults enjoy them as much as the kids.
