Description
The KATO 20-421 is a 124 mm (4-7/8′′) N Unitrack single-track straight viaduct — the half-length compact filler in the viaduct family, used at end-of-viaduct transitions or to fit awkward layout dimensions.
Elevated viaduct prototype: Reinforced-concrete urban viaducts carry modern Japanese commuter and Shinkansen mainline through cities — ribbon-of-rail above the streetscape on stone-faced concrete columns. The structural arches reproduce the prototype look perfectly.
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.
