The polystyrene sheet was coated in textured sealing paint, which I'd pigmented with some brown acrylic paint. Once dry this formed a hard, flexible surface that I could use as a base for scenic treatment. Point rodding stools from MSE https://www.wizardmodels.ltd/shop/signals/ls05/ were fitted to lengths of wooden sleepers and then glued in position alongside the trackwork. Ballasting was done using Woodland Scenics ballast using exactly the same method that I used on the main layout.
Back in April I mentioned that I was considering building an extension board for the layout that could be used at exhibitions.
The new board would hopefully have the following benefits.
1. It would eliminate the need to move the fiddle yard during shunting maneuvers.
2. If I give this base board full scenic treatment then the view under the bridge would be greatly improved!
3. My fingers couldn't be seen when moving the fiddle yard to set up roads
