Narrow gauge doesn't have to mean neglected. Many of the world's narrow gauge systems — the Swiss and Austrian lines above all — were engineered and maintained to full main line standards, and this is their track: Peco's 9mm gauge flexi with regular, evenly-spaced wooden sleepers, the properly-kept permanent way of a railway that means business. Code 80 nickel silver rail in flexible 914mm (36 inch) lengths, for OO (4mm) and HO (3.5mm) scale narrow gauge models.

One Gauge, Three Names

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

Maintained Mainline or Worn Branch?

The sleeper style is the character choice: this SL-404's regular spacing for the well-engineered look — Alpine feeder lines, modern preserved railways, anything run with pride — or the SL-400 "crazy track" with irregular sleepers for the charmingly unkempt old branch. Mixing them is prototypical too: tidy track through the station, weathered track out along the line.

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). 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 whatever radius the mountainside demands.
