How many O36 quarter curves make a full circle?
It takes 32 quarter curve sections (6-12023) to complete a full 360° circle with an O36 radius.
Is this compatible with other FasTrack pieces?
Yes, the 6-12023 uses the same patented locking connectors as all FasTrack sections, so it connects seamlessly with straights, other curves, switches, and accessories.
What's the difference between O36 and O48 curves?
O36 curves have a tighter 36-inch diameter circle, ideal for smaller layouts. O48 curves are wider at 48 inches, better suited for longer locomotives and more realistic sweeping turns.
