I've started taking into account logic, physics and topography when laying Coen's "Thomas the Tank Engine" track. You know you need to get out of the house when to say to your helping two year old, 'No, no son. A train could never take that curve after coming off so steep a hill. Too much momentum.".
(By the way, please note that I used the correct term 'Thomas the Tank Engine' instead of 'Thomas the Train')
Now if you'll excuse me. Coen is trying to connect the turn table waaaay too close to the switch track.
