Description
The Atlas 834 is a 4-piece pack of half-length 18′′ radius Code 100 curves — each section 15° of arc, the half-length companion to the standard 18′′R curve (#833).
Where it fits: 18′′ radius is the de-facto standard for HO mid-size layouts and reliably handles all 4-axle diesels, 40′ and most 50′ freight cars, and short passenger. Use #834 half-sections to step out of yard ladders, ease into S-curves, or close gaps where a full 30° (#833) overshoots.
