Description
The Atlas 833 is a 6-piece pack of 18′′ radius Code 100 curved Snap-Track — the de-facto standard HO curve, reliably handling all 4-axle diesels, 40′ and most 50′ freight cars, and short passenger.
Geometry: Each section is 30° of arc; 12 sections complete a full 360° circle. 18′′R is the inner-loop standard in double-track plans, paired with 22′′R outside (#836) at 2′′ track centers. Snap-Switches (#850, #851, #860, #861) diverge at the same 18′′R, so the curve drops directly into a turnout's diverging route.
