The guy at the hobby shop suggested that I use a foam board. I've read some previous threads about types of foamboard. Can any of you guys suggest a baseboard. The pros and cons of getting some plywood from the lumber yard vs. a foamboard. I'd like a 3'x4' or so layout on N-scale, but I'm intrigued about the idea of using a foamboard I'm using bachmann e-z track like in my previous post I asked about securing it to a board. The guy at the shop said foamboard would be lighter and easier to work with and take around if i wanted to. Those of you who have foamboard can you be specific about what type you have and how you would secure the track (bachmann e-z track) to it. I'm going to model a small midwestern town with a factory or something using Penn Central stock.
