Description
The KATO 20-100 is a 4-pack of N Unitrack curved track sections at 249 mm radius (9-3/4′′) and 45° arc — the tight-radius N curve, used for compact table-top layouts (where 282 mm or 315 mm is too broad to fit) and inner loops of double-track plans.
Geometry: 8 sections (two 4-packs) complete a full 360° circle. R249 reliably handles 4-axle diesels, 40-60' freight, and short passenger.
KATO N Unitrack system: Code 80 nickel-silver rail molded into a factory-attached ballasted plastic roadbed, with integrated UniJoiners. Unitrack is KATO's flagship N-scale track system established in the 1960s — the dominant N-scale sectional track worldwide.
