The next stage in my model railway was to add a tunnel section, the idea was to create a cliff edge across the rear quarter with space for a small airbase on top of the cliff and the train track tunnel section going into the cliff. I found an old sheet of blue insulation foam so used this to form my rocky outcrop.
This section is open from behind so de-railed trains can be recovered if required. I went with the following method to create the rocks which seemed to work well:
- Shape and form of the rock formations created by cutting blue insulation foam board to shape and gluing together using PVA.
- Rock like texture added by 'attacking' the blue foam with a saw/knife/fingernails, basically just tear it up! I tried to stick to straight line patterns to create the look I was after.
- Add some 'mud' to hide joins and add further texture. The 'mud' was created by mixing plaster, sand and PVA.
- Base coat the whole lot. I used a grey primer I had lying around, this acted as a good seal and base colour.
- Dark wash and light high-light(s) to bring out the texture. I used acrylic paints here with a black wash and light grey then white highlights.
- Finish of with a bit of mossy foliage.
