Description
The KATO 20-181 is a 2-pack of N Unitrack concrete-tie double track curve — a single roadbed carrying two parallel curves at R414 outer / R381 inner radius, 45° arc, with grey concrete ties. The modern-mainline double-track curve for high-speed corridor modelling.
Geometry: The 33 mm prototype centerline is maintained across the curve — outer radius 414 mm, inner 381 mm. Drop in as one piece, faster and more rigid than separate inner/outer single curves.
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.
