Peter Waldraff's N gauge scale model railroad diorama is a masterpiece of precision craftsmanship, electrical engineering, furniture making, and creative problem solving. The result of his inventing and labors is a tabletop that converts into a three-season display of a train moving through the mountains.
And Waldraff isn't done yet! He plans to make the device WiFi-enabled so that he can control it from a phone. That will make demonstrations even more amazing.
