Description
The KATO 20-025 is a 2-pack of N Unitrack double slab 124 mm (4-7/8′′) sections — ballastless slab double-track at half-length, for filling 33 mm-centre Shinkansen / high-speed mainline plans.
Slab track vs ballasted track: Slab track is the ballastless concrete-pad construction used on modern high-speed mainlines (Shinkansen, ICE, TGV-LGV, recent North American rebuilds). KATO's slab Unitrack reproduces the smooth grey concrete pad with embedded rails — perfect for modelling Japanese commuter lines, Shinkansen, or any modern high-speed corridor.
Double track Unitrack: A single roadbed piece carrying two parallel sets of rails at 33 mm prototype centres — the standard Japanese-prototype double-track centerline, also matching modern North American mainline practice. Drop in as one piece; faster and more rigid than two single tracks side-by-side.
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, used in everything from a Bullet-Train table-top to mainline club layouts.
