I have completed installation of the foam roadbed all the way from Chilcott’s Ck almost to Ardglen. I have also laid quite a bit more CV track base from Chilcott’s Ck through Kankool to just before the first peninsula.
The process was the same as outlined here when I did the Temple Court section.
Under where the turnouts are located at Kankool, I laid 3mm cork down instead of the foam. This was done to make it easier cutting out a hole for the future throwbar rather than trying to cut it out of the soft foam. In hindsight, I probably only needed a small section of cork directly under the toe of each turnout rather than under the whole turnout. That is what I will do on future turnouts.
Taking on board an idea from Andrew, I also commenced installing strips of the high density yellow foam to the sides of the spline. The idea here is to lay continuous foam strips along the spline to not only allow for shaping the trackbed, ballast profile and drainage, but to also make it easier to install the main scenery foam later on, rather than trying to cut many small irregularly shaped foam pieces to try and fit against the spline.
