Most track models a railway at its best; this one models a railway with character. Peco's irregular-sleeper flexi — "crazy track" to the narrow gauge community — has its wooden sleepers randomly spaced and slightly askew, exactly the way real narrow-gauge lines looked after decades of just-enough maintenance. In Peco's own words, it depicts "the slightly worn out old track of a picturesque old railway": Welsh slate lines, estate and quarry tramways, and — closer to home — the sugar cane tramways that thread Queensland's coast, whose 2ft gauge is precisely what 9mm track represents under 4mm-scale models. Code 80 nickel silver rail, 914mm (36 inch) flexible lengths.

One Gauge, Three Names

This is the track for narrow gauge models in OO (4mm) or HO (3.5mm) scale running on 9mm gauge — the scale British modellers call OO-9, Europeans call HOe, and Americans call HOn30. Same track, three traditions; if your locomotives run on 9mm wheels at these scales, this is their permanent way.

Worn Branch or Maintained Mainline?

The sleeper style is the character choice: this SL-400's irregular sleepers for the charmingly unkempt look, or the SL-404 with regular mainline-standard spacing for narrow gauge lines built and kept to main line standards, as many European systems were. Mixing them is prototypical too — tidy track through the station, crazy track out in the fields.

Fits the OO-9 System

Fully compatible with Peco's OO-9 Setrack rigid track range and the Streamline narrow gauge turnouts (SL-E491/495/496/497), so junctions and station throats build to match. Code 80 rail takes the standard SL-310 conducting and SL-311 insulated joiners — shared with Peco's N gauge range — and lays with SL-14 track pins. Flexi curves by hand to the tight, wandering radii that are half of narrow gauge's charm.
