I wanted a retaining wall with a back scene, I had chosen the Slaters O Gauge Dressed stone for the walling. This was fixed to the rear sheet and sprayed with Halfords primer grey, I painted individual stones on the sheet multiple tones of grey which was then given a wash of Ammo Mig dark grime. This gave a nice finish to the stone wall so I continued using this method, I built some retaining wall buttress which were added to the wall and were painted in the same way, these were then added to the wall in the required locations. I added a back scene from Model Railway Scenes which was cut around the retaining wall and other scenic items. I wanted to add some height to the scene so I built a stanchion to hold some three aspect lights and also some yard tower lights again from Railway Laser Lines.
