Having just watched Ken Patterson's video on his modular layout construction. Wondering how he handles the switch machine installs and track wiring with what looks like 2'' solid foam layered construction. Also wondering what roadbed Ken uses.  Considering building a new rr to replace my existing one. It's on the second floor of a 32' x 80' barn. I like the idea of being able to build a new rr while the existing one is still operated. This way down time could be shortened greatly. Would be much easier to remove the rr when that time comes in the future.

To All: A point of View--Model railroading and rail fanning is not a plug and play hobby, it is a challenging hobby, not for the lazy person. It is the road less traveled, it is expensive, time consuming, requires multiple skills and is not for everyone. We search it out. If we did not get a blank stare when we tell others we like trains and are model railroaders, I suspect we would take up a hobby that most others do not have. What is your opinion?

I was sent this photo with a request to know something about it.  I kind of recall seeing this somewhere before.  Can anyone supply the context for this?

I setout today, as it was quite hot and muggy out to enjoy being outside, to get the foam board glued down. I took off the precut pieces and labeled them so I was not trying to figure out what went where later. I went to get the caulking adhesive I had bought and turns out I didn't quite read the label right. The two tubes I got were safe for foamboard but further reading the label which I didn't do good enough I guess at the big box store said it was good for foam to wood but not foam to foam.
