Model railroading is a hobby that allows people to re-create the look of a real railroad. One of the most interesting things that you can do is create a mountain as a large land feature. This can be done with a simple can of spray foam.

  1. 1

    Begin by spraying a small circle of the spray foam. Start from a central point and work your way out. It should be about 6 inches across. Allow it to fluff up.

  2. 2

    Apply another layer of foam to the first layer in the same manner. Continue to do this until you reach the height you want.

  3. 3

    Allow the foam to dry completely. Carve the mountain with the knife to create flat areas or caves. Spray with paint or paints of choice. You may also spray a clear glue over the paint and add simulated grass to the mountain.
