Peco Setrack OO-9/HOe: track planner from your own stock
7 items with verified geometry. Enter what you have, let the Auto-designer lay ovals, passing loops and stations, and view it in 3D at your table size.
Narrow gauge on 9 mm: Peco Setrack OO-9 runs in OO9 (1:76, British narrow gauge lines like the Ffestiniog) and in H0e (1:87).
The track spacing of 34.7 mm is calculated from the manufacturer's dimensions of turnout and counter curve; Peco does not publish one. The roadbed width is an assumption.
