INTERACTIVE PLANNER

Model Railroad Layout Size Planner

Start with the people and the room. Track comes second.

Quick planner

Reach rule

Keep normal working reach comfortable. A deep scene may look impressive, but track near a wall becomes difficult to clean or rerail cars on. Build access hatches only when they are genuinely usable; open aisles are easier.

Plan for the future

Reserve a clean path for staging, an interchange, a branch or a future extension. Expansion is easier when it has been designed into the track plan instead of added after scenery is finished.
