Well, I'm finally doing it. After much planning I am finally laying track. I am building a couple of ntrak modules to go with the ones from the local club. I'm using cork for the road bed mounted on a styrofoam sheet. My problem is that I used the full double width of cork for the two main lines and they look fine. But I had planned on just using a single width for the yard tracks, which is what the modiles will be (hopefully). When I mount the track on the single piece of cork the ties just fit the width of the cork with no roadbed on either side. How does everyone else handel this? Should I use the full double width cork for the whole layout, or should I use something like sculptamold to create the shoulders, or should I just use lots of balast to build up the shoulders? Or should I just go with no shoulders? I don't recall ever reading anything about this particular problem and I'm just not sure how to procede.
