Rather than going out and buying a mountain with a tunnel for your model railway, make your own customized mountain. A homemade mountain with a tunnel will save you money and will perfectly fit the theme of your railroad -- such as winter scene, autumn harvest or desert landscape.
Determine how big the inside of the tunnel needs to be for your trains to run through it smoothly.
Sketch a plan for the mountain, including measurements from Step 1 and the location on the track where the mountain will go.
Bend chicken wire into the shape of the interior of the tunnel. Cover it with plastic wrap.
Rip newspapers into approximately 1-inch-wide strips.
Soak the paper strips in a watered-down plaster slurry.
Cover the chicken-wire form completely with the plaster-soaked paper strips.
Mold modeling plaster over the form, shaping it into a mountain. Allow it to dry completely.
Paint the mountain to match your railway's theme. Add grass, trees, rocks, pebbles, dirt, fake snow or even small plastic animals.
Paint the interior of the tunnel black or dark brown.
Cover the entire finished product with acrylic finish for protection.
Things You'll Need
- Chicken wire
- Plastic wrap
- Plaster and water slurry
- Modeling plaster
- Miniature railway details (trees, rocks, grass, fake snow or animals)
- Acrylic finish
- Dry brushing is accomplished by using a small amount of paint on a dry brush and lightly going over the high places on the mountain.
- Use real rocks from your yard and garden and glue them to the mountain to serve as boulders.
- Only mix as much plaster as you can use in 15 or 20 minutes. If the plaster gets too thick to work, try adding a little more water to it.
- Wear safety goggles whenever working with power tools.
- Use caution when cutting and handling chicken wire because the sharp wire can scratch and pierce your skin.
