How to choose a benchwork height
There is no single correct height. Benchwork height is a balance between how well you can see the trains, how comfortably you can reach into the scenery, and who will use the layout. Many hobbyists build somewhere around elbow height or a little higher, which commonly falls roughly in the range of 40 to 50 inches, but individual preference varies a lot.
Higher benchwork:
- Gives a closer eye-level view, which can look more realistic.
- Is easier on the back when working on track and wiring.
- Can make reaching across the layout and seeing the far side harder.
Lower benchwork:
- Makes reaching easier for some people, and suits children and seated operators.
- Gives a more aerial view of the trains.
- Often means more bending and kneeling for under-layout work.
A practical test is to stand at a table or counter of different heights while holding a small object, and notice which height lets you work comfortably for an hour or more.
Height by layout type
- Adult-only home layout: Often mid-range, aiming for a view at or just below eye level for much of the scene.
- Family or kids’ layout: Lower, or consider a step stool or adjustable legs.
- Seated operation: Lower and with careful reach depth so you do not strain.
- Club or modular layouts: Follow the club’s or standard’s height requirements so sections fit together.
- Staging or hidden yards: May sit lower than the main scene, which saves space in multi-level designs.
Reach depth matters as much as height
A layout that is too deep to reach across invites damaged scenery. Many builders try to keep any area along an aisle to roughly an arm’s length, around 24 to 30 inches, and use access hatches or removable sections for deeper areas. Corners are especially tricky, so consider a lift-out section or a crawl-in.
Common benchwork styles
- Open-grid: A frame of lumber joists with plywood or other roadbed on top. Flexible and allows terrain to drop below track level.
- L-girder: Long girders with joists attached, typically supported on legs. Strong over long spans.
- Table-top or solid surface: A flat panel on a frame. Simple and good for small layouts, but scenery below track level is harder.
- Foam-top: Foam over a lightweight frame, often used for scenery in sections.
Best wood and plywood thickness
Common choices include:
- Pine and fir (dimensional lumber): Easy to find and cut. Check for warped or twisted boards and choose straight ones.
- Plywood: A stable sheet material for tops, risers and sub-roadbed. Cabinet-grade or birch plywood tends to hold up better than thin sheathing grades.
- MDF: Can be used, but it is heavy and can swell with moisture.
Plywood thickness depends on span and support. Many hobbyists use 1/2 inch or 3/4 inch plywood for tabletops, and thinner sheets, such as 1/4 inch, for fascia or small parts. Thinner sheets generally need closer framing support. If you are unsure, add more support rather than less.
Foam and other materials
Extruded foam board can be used on top of a frame as a base for terrain and sometimes track. It is light and easy to carve but does not provide structure on its own, so it still needs a rigid frame below. Hollow-core doors and shelving brackets are sometimes used for small or temporary layouts.
Building simple open-grid benchwork
- Plan the footprint, keeping access and aisles in mind.
- Cut frame members to length and assemble rectangles with screws and glue.
- Add joists across the frame, commonly spaced around 16 to 24 inches apart, with closer spacing for thinner tops.
- Attach legs, adding cross braces so the frame does not rack.
- Fit adjustable feet if the floor is uneven.
- Add the plywood or foam top and fasten it securely.
- Check that surfaces are level before laying track.
Pre-drilling and using screws instead of nails makes later changes easier. Wear eye and hearing protection when cutting, and follow the safety instructions for your tools.
Think ahead about scenery and backdrops
Leave space for scenery and the backdrop. A layout with a painted backdrop needs a rigid, smooth surface along the back. For how terrain sits on the benchwork, see our overview of model railroad scenery.
FAQ
How tall is an HO model train? HO scale is 1:87, so a typical freight car or locomotive is on the order of 1.5 to 2 inches tall, depending on the prototype. This is why a lower eye level makes a layout feel closer to ground level.
What is the best wood for model railroad benchwork? Straight dimensional lumber such as pine or fir for frames and good-quality plywood for tops is a common and practical choice.
How thick should plywood be for a train layout? Many people use 1/2 or 3/4 inch plywood, with supports spaced to keep it from sagging.
How do I build model railroad benchwork? Build a rigid frame, add joists and legs, brace it, level it and then fasten the top, as outlined above.
