Track plan generator: a layout from the track you own

Most track plans start with a shopping list. TrackDrawer turns that around: you start with the track already in the box or drawer, and the Auto-designer works out which layouts you can build with exactly those pieces. Every plan closes, fits your table and uses only pieces you own.

It works for model railways from Z to G scale and for toy track: IKEA Lillabo, LEGO and Duplo. Nothing to install; the app runs in the browser, also on your phone.

How it works

  1. Enter your collection: Type in your track by article number, or add a whole starter set or extension set at once. The app knows the real dimensions of every piece.
  2. Choose a table: A rectangle, an L or U shape with an edge margin, or the floor, where the area grows with what you lay.
  3. Auto-designer: Choose what you want: running round, a station, several trains or variety. The Auto-designer lays variants from exactly your pieces, 5 at a time for free and up to 50 with Pro. With "Use as many pieces as possible" the largest variants come first.
  4. Checks: Every plan is checked: closure errors, collisions, gradients that are too steep and too little clearance show up at once. The gap finder searches your collection for the pieces that close a last gap exactly.
  5. 3D and 1:1: View the plan in 3D and print it as a scaled PDF. With Pro the print comes at full size on A4 tiles, so you can lay the track right on the paper.

Which shapes the Auto-designer lays

Ovals, diamonds, triangles, hexagons and octagons, dogbones, L, U, S and T shapes, figure eights with a crossing or a bridge, and lines with two reversing loops. On top come passing loops, sidings, stations with two platforms, yards and double track with a crossover, each only when your collection has the turnouts and straights for it.

Plans with a bridge or a gradient are saved with Pro; flat plans up to 60 pieces are free.

Examples from the Auto-designer

The Auto-designer laid these plans itself, from starter sets and ordinary collections. Open one to see it full size.

Questions about the track plan generator

Do I need to buy more track?

No. The Auto-designer only uses what is in your collection. If you keep drawing yourself, the parts list shows what you use, what you have and what you are missing.

What table size do I need?

You choose it, and the Auto-designer sticks to it. Each example on this page shows its table size. For toy track you pick the floor, where the area grows with the layout.

Is the track plan generator free?

Yes, for one flat plan of up to 60 pieces, with 5 variants at a time. Pro (29 euros a year) removes the limit, gives up to 50 variants at a time and adds gradients, bridges and the 1:1 print.

Does it work for IKEA Lillabo, LEGO and Duplo too?

Yes. Wooden track, LEGO train track and Duplo are included with their own curves and switches or junctions. The ideas pages show examples.

How accurate are the plans?

Every piece is recorded with the manufacturer's dimensions. Circles close within 1 mm and 0.5 degrees; a plan that does not close shows up in red right away.
