Today I (Daniel) built a complicated wooden train track set-up. Beneath are a few photographs of it. I have entitled it "Who's on top?" It was built for Anna and Ezra to play with. If you look you will notice that every raised bridge has a track going under it. The entire track only has one dead end! If you were an engineer of a wooden train on theis track a map, gps, and anti-collision technology would all be VERY USEFULL.

Encyclopedia junction with three levels of track!

The older you get the more complicated the tracks will become!
