Modeling scenery elevation with insulation foam

    To model elevated scenery on your layout start out with at least 1/2 inch foam before laying any track. This will allow you to carve small gullies or a ditch. If you want a deeper depression go with thicker foam. This works great for below track level scenery and you will notice the improvement right away. For scenery above track level simply add more foam in layers till you reach the desired elevation. Next carve away the corners to make the levels blend together and then add your ground foam to finish.
    You can go to my "Boston Mountain Sub Division" and"Double Track Layout" albums to see what this suggestion looks like on a flat track layout.

    How do you do your bridges, do you lay your track and then cut away for the bridges or put the bridges in first? The results look nice. I have not tried that yet, but I am going to on my next layout.

    I want to build a steel trestle on the south end of module 08. The plan at this time is to assemble a Micro Engineering steel trestle so I can get the actual height then build the module and foam stack up.

    The thing to remember is how the water flows on your layout. We spend a lot of time determining how the tracks go so spend the same time on water flow. Try to avoid the "Dead Sea" scenario. Go with the flow.

    I like to use blue 1/2 inch and pink 3/4 inch insulation foam on top of a 3/4 inch Birch plywood base to model scenery below track level. The foam is easy to carve with a keyhole saw and a rasp file. A foam stack up of 1 1/4 inch equals a little over 9 feet in HO scale and just shy of 17 feet in N scale, enough for a small stream or ditch. The blue foam acts like a warning track to keep from carving too deep, to barrow a baseball term. To add more elevation above track level, stack more foam on top of the base layers, round off the edges and corners and pay attention to how water would flow to avoid standing water situations.
