Free track plans are one of the best ways to learn layout design. You can study how other modelers fit track into a space, then copy a plan as-is or modify it to your needs. The challenge is not finding plans, because there are thousands, but choosing one that will actually work for you.
Where to find free track plans
These are well-known sources. The size of their collections changes over time, so check each site for current details.
- FreeTrackPlans.com: a collection of several hundred designs, mostly for HO and OO track, from small branch lines to large terminals. The plans were drawn in AnyRail, and the source files are offered for download.
- SCARM track plan library: a user-submitted database of layouts that can be filtered by scale, size, and other criteria. Many entries include downloadable SCARM files, plus details like dimensions, track brand, and era.
- Model Railway Ideas: a large library of layout ideas and plans for many scales and track brands.
- Trains.com track plan resources: Model Railroader’s site offers a track plan database and beginner-oriented plans, along with articles about planning.
- Bob’s Track Plans: a showcase of designs created for specific clients. These are mainly examples of what a custom plan looks like, and they can be a good source of ideas about use of space, hidden staging, and aisle widths.
- Forums and club sites: many hobbyists post plans and ask for feedback, which is a good way to learn what works.
Also look at libraries and used book sales. Classic collections such as 101 Track Plans for Model Railroaders have been popular for decades, although you may need to buy a copy.
What the file formats mean
- PDF or image: you can print and study these, but you cannot edit them. They are fine for inspiration.
- SCARM file: opens in SCARM software, where you can view the plan in 2D and 3D and then change it.
- AnyRail file: opens in AnyRail software, so you can adjust track, scale, or brand.
Free versions of planning software often limit the number of track pieces, so check the limits before you commit to a program.
How to judge a free plan before building it
A plan can look excellent and still be a poor fit. Check these points:
- Scale and track brand. A plan drawn with sectional track may not use the turnouts and flex track you plan to buy.
- Minimum radius. Compare it with your longest locomotive and cars. Many plans, including some set-track designs, use very tight curves that will not suit large equipment.
- Turnout size. Look for the turnout number or brand and confirm that you can buy it.
- Grades. If the plan has bridges or helixes, check how steep the approach is. The NMRA’s planning guide warns that grades above roughly 2% significantly affect locomotive performance.
- Reach. Look for turnouts or tracks more than an arm’s length from any edge.
- Aisle and door access. Many plans show only the table, not the room.
- Operation. Does the plan have a passing siding, a place to stage trains, or industries you want to serve?
- Source. Some plans come from working layouts; others have never been built. Treat unbuilt plans with some caution.
Adapting a plan to your space, scale, and track brand
Most free plans can be modified:
- Adjust the footprint by changing the lengths of straights, if the curves stay the same.
- Replace sectional track with flex track for broader curves.
- Move turnouts closer to edges to improve reach.
- Move to a different scale by converting dimensions. Going from HO to N, for example, makes the layout much smaller, but you will want to re-check curves against your equipment.
Our guide to designing a model railroad track plan explains the design rules behind these changes.
Matching plans to a goal
- Watching trains run: choose a continuous loop with a passing siding or two.
- Switching and operations: choose a shelf or compact switching plan with several industries and a run-around.
- Small space: look at small table plans or shelf plans. Plans around 4x8 feet are very common, and many HO examples are covered in our guide to HO model railroad track plans.
- Bigger ambitions: look for around-the-wall plans with staging, such as those shown on custom design sites.
If you are still deciding between these styles, read our overview of model train layouts.
Free tools to draw your own
When you outgrow existing plans, you can try planning software with a free tier, graph paper, or printable turnout templates from manufacturers. Pencil and paper still works well for a first draft.
Mistakes to avoid
- Copying a plan without checking radius against your equipment
- Ignoring how a plan fits your room, doors, and aisles
- Trusting dimensions given in different units without double-checking them
- Choosing a plan far bigger than you can finish
- Forgetting to leave room for scenery, which affects how realistic your layout looks
