Cool things with wheels since 2006
I know abolutely nothing about trains, but I have to imagine that locomotives never go any further than the one in the picture. They couldn't turn that tight. I would guess that only very small vehicles (like a motorized version of the hand powered carts like you see in the western movies, small enough that the wavy tracks are of no consequence.) ever go on the single track that is somewhat perpendicular to all the other traks.
No, it's a really long telephoto lens - like birdwatchers use. Probably a football field worth of track there.
