Episode II involved their friend coming over: http://www.youtube.com/watch?v=zEssEmMIuwo, I like this one because they complain about hitting their heads under the table. Dominic and Rocco both insisted on a low (2’ high) layout so they could reach everywhere. So I am making them wire it on their own. It has been good for them, they even roped their friends into the work.
Their next one will be about how they built it and how it works.
The layout you see is the only one in the house. I have been thinking about an N-Scale layout, but since this one is not done yet (of course, it may never truly be “done”) I can’t justify starting a new project. I also think these guys could not keep their hands off, and I think N-scale would be a little delicate for them.
The first one was too wide and they could not reach. The design was to allow them access (max reach distance needed to be less than 2’ for their short arms but it is more interesting to run as well.
