How much space do you have?

Leave both fields empty for unrestricted floor space, or enter a maximum footprint.

The estimate includes the modeled track footprint plus a 5 cm margin on each side. A 90° rotation of the complete plan is allowed.

A track planner that starts with what you already own

RailPako is designed around inventory-first planning: enter the tracks in your box, choose a layout that fits your space, and keep the construction order with the plan.

How RailPako works

1. Count your tracks

Enter the supported straight and curved pieces. No account is required.

2. Generate validated layouts

The geometry engine checks closure, heading, inventory limits and conservative track proximity.

3. Build from the numbered plan

Open a layout and follow the exact sequence one piece at a time.

4. Reuse or resell

Optionally divide loose tracks into non-overlapping buildable bundles.

Current v0.2 scope

This preview models S16 straight and R40 / 22.5° curve assumptions only. Switches, crossings, flexible track, physical clearance and exact product compatibility remain separate verification work.
