The Y point's companion piece. Peco's ST-247 Y turnout splits symmetrically, both roads curving away at a gentle 859.6mm radius — and this special curve is that exact geometry as plain track, continuing either diverging road smoothly onward. Add one after each leg of a Y and the formation flows; it's the difference between a junction that fits the Setrack grid and one that leaves you improvising angles. 11.25° of arc, Code 100 nickel silver, rail joiners fitted.

Where It Fits

Primarily: after the ST-247 Y point, one per diverging road, as Peco's geometry intends. But an 860mm-radius curve is also the sweeping-est piece in the Setrack repertoire — thirty-two to a circle nearly 1.7 metres across — so planners also press it into service anywhere a barely-perceptible curve beats a dead straight: gentle transition easements, sweeping mainline corrections, and the graceful approach curves that make a layout look less like a train set.

Track That Grows With You

Fully compatible with Peco Streamline Code 100 and the sectional ranges from Hornby and Bachmann. SL-11 insulated joiners for section breaks, ST-280 nails for pinning, and the standard Setrack promise: nothing here gets discarded when the layout gets serious.
