Here are samples of the system used-PECO. This is their Hom track with 12mm gauged rail. I had considered using some of Hugh's excellent handbuilt points with Society sleepers but as I have been invited to an exhibition already, then this was the easy and quicker option. Don't worry- the copperclad points are earmarked for another project.
The advantage with the PECO product is that it is quick to lay and robust for exhibition purposes.
