This is a fully functioning train yard. The upper redstone lantern shows which slot the minecart will go to if sent. The lower light shows that a slot is full. The switch room is very simple. Each button corresponds with a switch on the track, shown by where the button is compared to the other buttons. This project takes up LOTS of space underground, so make sure you get it all if you're copying it with MCedit. This project also uses relative coordinates for everything, so as long as it is only being moved, not rotated, you should be good.

The world save also has a few other rail type items, more are added from time to time. See update log for details.
