Hills & Landforms

Every scene starts with shape. Foam is light, clean and easy to carve, and a plaster shell turns it into hard, paintable ground. Get the shape right here and every layer after it looks better.

BeginnerA weekend6 videos

Step by step

  1. 1

    Plan the land

    Mark where the track, roads, buildings and water will go. Keep building sites and road areas flat, and let the land rise and fall everywhere else. Real ground is rarely level.

  2. 2

    Stack and carve foam

    Glue foam sheets together with a foam-safe glue such as Foam Tack Glue or a low-temp foam glue gun. Carve rough hills with a foam knife or hot wire cutter. Use risers and inclines to lift the track on smooth, even grades.

  3. 3

    Fill and smooth

    Fill seams, gaps and dents with Foam Putty and let it dry. Rough is fine: the plaster and ground cover will hide small bumps.

  4. 4

    Add the plaster shell

    Dip plaster cloth in water and lay it over the foam in overlapping strips, smoothing each one with your fingers. Add a second layer where the shell needs to be stronger. For rugged, sculpted shapes, bend Shaper Sheet to the form you want and plaster over it.

  5. 5

    Kill the white

    Brush Earth Undercoat thinned with water over every bit of white plaster and let it run into the folds and low spots. Woodland Scenics says it should look slightly translucent. If ground cover ever thins out, earth shows through instead of white.

Rocks & Cliffs

Rock castings are the fastest way to add drama: cliffs, cuts, outcroppings and creek beds. Cast them in plaster from flexible molds, set them into the hillside, then bring them to life with thin washes of color.

Beginner1–2 evenings + overnight dry7 videos

Step by step

  1. 1

    Wet the molds

    Mix "wet water": about two drops of dish soap in a cup of water. Spray it inside the rock molds and pour out the extra. It stops air bubbles. Prop the molds level in a box of sand or on wadded paper.

  2. 2

    Mix and pour

    Sift Lightweight Hydrocal into water (Woodland Scenics uses 8 oz of Hydrocal to 3 fl oz of water for castings), stir gently for about 30 seconds and fill the molds a third to half full. Tap them to release bubbles. Unmold after 30–40 minutes.

  3. 3

    Set the castings

    Break the castings into varied pieces and test-fit them with the rock layers (strata) running horizontally. Wet the plaster where they'll go, butter the backs with a thicker Hydrocal mix, press them in and fill the gaps. Let them dry at least 12 hours.

  4. 4

    Leopard-spot the color

    Thin Burnt Umber and Yellow Ocher Earth Colors about 1 part to 16 parts water, and Black about 1 to 32. Dab umber over a third of the rock, ocher over another third, leave a third white, then wash Black over everything to tie it together.

  5. 5

    Add talus

    Sprinkle talus (rock debris) below cliffs, in erosion gullies and around tunnel portals. Glue it with equal parts Scenic Glue and water plus a drop of dish soap, applied with an eyedropper. Add a second coat once the first is dry.

Roads & Paved Areas

Roads go in before the grass, so the ground cover can run right up to the pavement edge. Woodland Scenics' Road System uses paving tape as forms and Smooth-It as the pavement: no cutting, no seams.

Intermediate1–2 evenings5 videos

Step by step

  1. 1

    Draw the roads

    Pencil in roads, parking lots and foundations on flat areas, then test-fit your buildings. Woodland Scenics suggests 2½ in. for an HO country road and 4⅛ in. for an HO city street. Use the Scale Size Finder below for your scale.

  2. 2

    Lay the paving tape

    Stick Paving Tape along your lines. At grade crossings, butt the tape up to the rails and cut strips to fit between them.

  3. 3

    Pour the pavement

    Mix Smooth-It (Woodland Scenics: 2 cups to ¾ cup water) and spread it between the tapes with the spreader, level with the tape tops and rails. Let it dry about 30 minutes.

  4. 4

    Open the flangeways

    Pull the tape, then run a hobby knife along the inside of each rail a few times to cut a groove for the wheel flanges. Roll a car through and repeat until nothing bumps.

  5. 5

    Sand, paint and stripe

    Sand lightly with 220-grit, then paint roads with Asphalt Top Coat and sidewalks and foundations with Concrete Top Coat. Add lane lines with striping pens, then cracks, patches and oil stains.

Ballast & Track

Ballast is the crushed rock that holds real track in place, and nothing makes a layout look finished faster. The trick is simple: spread it dry, make it level with the ties, wet it, then glue it.

BeginnerAn evening per 10–20 ft6 videos

Step by step

  1. 1

    Pick the size and color

    Match the stone size to your scale (see the Ballast tab in the Scale Size Finder). Mainlines usually get clean gray ballast, while yards and branch lines look right with cinders, darker or weedier ballast.

  2. 2

    Glue the shoulders

    Brush a little Scenic Cement on the sloped sides of the roadbed, keeping it off the rails.

  3. 3

    Spread it dry

    Pour ballast between the rails and down the shoulders. Stay away from turnout points, throwbars and switch machines.

  4. 4

    Level and clean

    Brush the ballast off the rails and tie tops with a soft, wide brush until it sits level with the top of the ties. Tap the rails to shake loose grains off the ties.

  5. 5

    Wet, then glue

    Mist the ballast first so the glue can soak in (Scenic Cement has a wetting agent; Woodland Scenics says mist, then saturate). Then flood it with Scenic Cement from an eyedropper or sprayer until it's soaked through.

  6. 6

    Check and clean

    While it's still wet, throw every turnout a few times so nothing glues solid. When dry, clean the rails before running trains.

How-To 05 · Ground & grass

Ground Cover & Dirt

Ground cover is the base coat of nature. Real ground is never one color: it's dirt, dry patches, green growth and debris all mixed up. Build it in thin layers and let a little earth show through.

BeginnerAn evening per area7 videos

Step by step

  1. 1

    Start with earth

    Paint the terrain an earth color first (Earth Undercoat over plaster). Any gap in the ground cover then looks like dirt, not white plaster.

  2. 2

    Mist and sprinkle

    Work a few square feet at a time. Mist the area with Scenic Cement, then sprinkle a blended turf, leaving some earth showing.

  3. 3

    Add accent colors

    Sift Burnt Grass and Yellow Grass fine turf where the ground gets little water. Use Soil and Earth colors in ditches, gullies, trails and creek beds.

  4. 4

    Add texture

    Sprinkle coarse turf for weeds, coarse grass and small plants. Avoid rock faces.

  5. 5

    Lock it in

    Mist the whole area again with Scenic Cement. Add glue between layers as you build up.

  6. 6

    Flyspeck it

    Fold a sheet of paper into an L, put a pinch of Soil fine turf on it, and gently puff it onto glue-misted rocks and grass. Woodland Scenics calls this flyspecking: instant dust and dirt.

How-To 06 · Ground & grass

Static Grass

Static grass is the single biggest upgrade most layouts can get. An applicator gives the fibers a static charge so they land standing up in the glue, like real blades of grass. Three things make it work: glue, not too much grass, and mixed colors.

BeginnerAn hour + 4 hours drying6 videos

Step by step

  1. 1

    Pick your lengths

    Use the Grass tab in the Scale Size Finder to choose fiber lengths for your scale: short for lawns and pasture, longer for weeds and meadows.

  2. 2

    Glue a small patch

    Brush a thin, even layer of static grass glue over a small area. Work small: if the glue skins over, the fibers won't stick. No glue, no standing grass.

  3. 3

    Load the applicator

    Fill the hopper only about a quarter full. WWScenics' tip: if it's packed, the fibers can't move around to pick up a charge.

  4. 4

    Apply the first layer

    Switch on, hold the hopper about an inch above the glue and shake gently side to side. Stop once the glue is covered. Too much grass makes it lie flat. On WWScenics applicators, keep the clip close to the hopper; no nail in your scenery needed.

  5. 5

    Layer it

    Mist a layering spray adhesive over the first layer and add longer fibers in patches. Mix in dead, straw and patchy colors. Nature is never one green.

  6. 6

    Let it dry

    Leave it for about four hours, then vacuum up the loose fibers. Put a stocking over the nozzle and you can reuse them.

Tufts, Bushes & Weeds

This is the in-between layer that makes scenery believable: bushes along fence lines, tufts at the base of rocks, weeds against foundations, vines on the hillside. A little goes a long way.

BeginnerAn evening8 videos

Step by step

  1. 1

    Plant bushes in families

    Bushes tend to grow in groups of one kind, so keep each color together in clusters. Test the placement, then glue them down with Scenic Glue.

  2. 2

    Highlight and seal

    Sprinkle a little Yellow Grass fine turf on top as sunlight highlights, then mist lightly with Scenic Cement.

  3. 3

    Add tufts

    Peel 'n' Place tufts go anywhere a mower can't reach: along the track, fence posts, rocks and building corners. Plant them in loose, odd-numbered groups.

  4. 4

    Plant field grass

    Roll a small clump of Field Grass between your fingers, trim it to length, dip the cut end in Hob-e-Tac and hold it in place for a few seconds.

  5. 5

    Stretch vines and flowers

    Pull Poly Fiber or Flowering Foliage thin and lacy, press it onto the hillside, add a pinch of turf and mist with Scenic Cement.

Trees & Forests

Trees are the biggest thing in most landscapes, and real ones are much taller than most people expect. Build them in batches, vary the shapes and colors, and plant them in groups.

IntermediateAn evening per batch8 videos

Step by step

  1. 1

    Size them right

    Use the Trees tab in the Scale Size Finder. A 60-ft oak is about 8¼ in. tall in HO and 4½ in. in N.

  2. 2

    Armature trees: shape and glue

    Twist and bend plastic armatures into a 3-D shape. Paint Hob-e-Tac on the branches and wait about 15 minutes until it's clear and tacky.

  3. 3

    Armature trees: add foliage

    Dip the tree in Clump-Foliage, or press on pieces of Fine-Leaf Foliage until it's as full as you like. Sprinkle a little fine turf on top for highlights, then mist with Scenic Cement.

  4. 4

    SuperTrees: prep and soak

    Break natural SuperTree clumps at the Y and trim them while dry. Soak them in matte medium thinned 1 part to 7 parts water for at least 30 seconds. Scenic Express says to use only matte medium, not thinned white glue or hairspray.

  5. 5

    SuperTrees: flock and dry

    While they're wet, sprinkle leaf flake or foam onto the tops of the branches, where leaves really grow. Hang them upside down on a line with clothespins to dry.

  6. 6

    Plant them

    Poke a hole in the scenery, add a drop of glue and push the tree's pin or trunk in. Group trees of different heights, and fill the back with Forest Canopy so it reads as a forest.

How-To 09 · Water

Water, Rivers & Waterfalls

Model water is mostly paint. The depth you see comes from the colors under a thin clear layer. Do the landscaping first, paint the bed dark in the middle and light at the edges, then pour.

Intermediate2–3 days (mostly drying)8 videos

Step by step

  1. 1

    Paint the bed

    Paint the deepest areas darkest (center of the river, under waterfalls) and blend to lighter earth tones toward the banks. Let it dry completely, and keep Scenic Cement off the water area.

  2. 2

    Place the details

    Set rocks, talus, dead fall and anything else in the water now, glued down with a little Realistic Water. Let it dry before you pour.

  3. 3

    Dam the edges

    Tape the edge of the layout where the water meets it, so the pour can't run off. Peel the tape after it dries.

  4. 4

    Pour in thin layers

    Realistic Water goes on up to ⅛ in. at a time and dries clear in about 24 hours (milky at first is normal). For deeper water, Deep Pour goes up to ½ in. per pour; wait about 4 hours, until it's sticky, before the next layer.

  5. 5

    Add motion

    Shape ripples and splashes on top with Water Effects. For a waterfall, spread Water Effects on a non-stick surface, let it cure overnight, peel it off and glue it in place. Dab white highlights where water churns.

Snow & Seasons

Picking a season gives a layout a story. Spring is bright green, late summer goes gold, fall brings reds and oranges, and winter covers it all in white. Pick one and stick to it across the scene.

BeginnerAn evening5 videos

Step by step

  1. 1

    Pick a season

    Choose your ground cover, static grass and foliage colors to match: fresh greens for spring, golds and straw for late summer, reds, oranges and dead grass for fall.

  2. 2

    Glue where snow lands

    Mist Scenic Cement where you want snow. Snow settles on flat ground, roofs and the tops of branches, and drifts against walls and fences.

  3. 3

    Sprinkle and repeat

    Sprinkle Soft Flake Snow onto the wet glue. Repeat for a heavier cover, then mist again to seal it.

  4. 4

    Make drifts

    Pour snow into piles where wind would drift it and soak it with glue to lock it in place.

  5. 5

    Frost and fall

    For frost on grass, apply fine static snow fibers over grass. For fall, sprinkle leaf flake over the ground and in the trees.

Weathering & Final Details

The last ten percent is what people notice. Step back, look at the scene like a photo and add the little things real places have: rust, soot, dust, trash, fences and a clean finished edge.

BeginnerOngoing8 videos

Step by step

  1. 1

    Look for what's missing

    Add ballast along road shoulders, litter in the woods, debris along fence rows and bushes around building foundations. These are the details that make a scene real.

  2. 2

    Weather the track

    Paint or powder the rail sides rust brown and add grime between the rails. Clean the railheads afterwards so trains still run.

  3. 3

    Weather rocks, walls and structures

    Brush on weathering powders: soot near tunnel portals, rust streaks under metal, green moss where water runs.

  4. 4

    Paint the edges

    Sand the layout edges smooth and paint them a dark color. It frames the scene like a picture.

  5. 5

    Add a backdrop and details

    A sky or scenic backdrop makes the layout feel bigger. Then add buildings, people, vehicles and signs last.

Scenery FAQ

What order should I build model railroad scenery in?

Shape the land first (foam and plaster), then rocks, then roads and ballast, then ground cover, static grass, bushes and trees, then water, and finish with weathering and details. Woodland Scenics follows the same sequence: rocks and earth color, roads, ballast, landscaping from low to high, water, then finishing touches.

What length static grass should I use for HO scale?

For HO, 1–2 mm fibers read as a mowed lawn or short pasture, 4–6 mm as tall field grass, and 10–12 mm as wild meadow and weeds (roughly 3 ft tall). Use the Scale Size Finder on this page for any scale.

What length static grass should I use for N scale?

In N scale, 1–2 mm looks like pasture, 4 mm like tall field grass and 6 mm like weeds about 3 ft tall. For a mowed lawn, fine turf works better than static grass.

What size ballast should I use?

Real mainline ballast stones are roughly 1 to 2½ inches. Based on Woodland Scenics' size chart, Fine ballast is closest in HO and N, Fine or Medium in O, and Coarse in G. The Ballast tab in the Scale Size Finder shows what each size represents in your scale.

What glue do I use for ballast?

Woodland Scenics Scenic Cement, or diluted white glue. Mist the ballast first so the glue can soak in, then saturate it with an eyedropper. If you only wet the top, the ballast underneath stays loose.

Why won't my static grass stand up?

Usually one of three things: not enough glue (or it had skinned over), too much grass applied at once (it falls flat), or an overfilled applicator hopper. Fill the hopper about a quarter full, work small areas, and stop once the glue is covered.

How tall should model trees be?

Taller than most people think. A 60-ft oak is about 8¼ in. tall in HO, 4½ in. in N and 15 in. in O. Use the Trees tab in the Scale Size Finder for any tree height and scale.

How deep can I pour Realistic Water?

Woodland Scenics Realistic Water goes on in layers up to ⅛ inch and dries clear in about 24 hours. For deeper water, Deep Pour Water goes up to ½ inch per pour, with about 4 hours between layers.

Can I use real dirt for scenery?

Yes. Sift it fine, dry it, and run a magnet through it to pull out iron particles that could end up in locomotive motors. Glue it down like any other ground cover.

Where can I buy scenery supplies?
