I now have a 10'x 10'6" room to build my railroad. I have painted the walls a sky blue and have the bench work roughed in as you can see in the photos. The benchwork is mostly an open L-girder design with 1/2" plywood on top to support the foam bard. I am planing on using the foam board to allow me to sculpt terrain and finish it off with scenery so I don't have to use very much plaster to build the landscape. I am also going to be using geodesic foam scenery that I have already started using on the first layout that has now been completely scraped except for the scenery that I had built.
This section has the foam board applied and is ready for the sub roadbed to be added. I am using a type of foam board that is not exactly what I wanted but I am hoping to get the extruded foam board that is what most modelers use. This type has a foil layer that has to be removed in order to have access to the foam to sculpt contours and ditches to give the landscape some life.
The next step is to start painting the back drop before I get to much further along and it become more difficult to paint.
