The Kato N Scale Unitrack modular roadbed track system features nickel-silver rails fully integrated to a remarkably realistic-looking roadbed with simulated wood ties. The patented Unijoiners (included) lock the track sections together firmly and evenly. The frustration of derailments resulting from uneven rail joints and separating sections is eliminated. There′s no need to glue down cork roadbed tack down track sections and file rail connections smooth after soldering. Simply snap it together and you′re ready to go. Track sections are compatible with Kato N Scale Unitrack sets and accessories. Allows transition from Unitrack to TomyTec Fine Track N Scale track systems.
