Daddy + Time + Thomas tracks = Dangerous
Over the long weekend, the kids asked me (as they often do) to play Thomas with them. Rather than building one of the pre-fab track designs that came with the track sets that we and Grandma and Papa purchased, I decided to experiment. The track design above is what I came up with using the maximum number of pieces from our collection.
I discovered an "instability" in the original design: the turn above the bridge originally went to the right. With that design, once you ended up heading in the clockwise direction on the outermost loop, there was no way to reverse course. Changing that to a left-going turn made it possible to traverse any section of track in either direction (trust me, I've proven it to my satisfaction).
So, there you have it.

The scary thing is that I verified your proof.
