Kato N Scale Unitrack makes it easy to start with a simple loop and keep building from there. Shop straights, curves, turnouts, crossovers, track sets, double track, viaduct, Unitram, and other Kato N track for everything from compact layouts to larger railroads.
Find new and pre-owned pieces for your next expansion through Kato Trains and Kato N Scale, or compare N Scale Track across manufacturers.
Kato N Scale Unitrack is designed to make it easy to build a railroad, run trains reliably, and change the track plan when you're ready for something bigger. The molded roadbed and removable UniJoiners create secure connections while allowing sections to be assembled, separated, and reused.
That flexibility works for everything from a first tabletop loop to a permanent Kato N Scale layout with switching, double-track mainlines, crossovers, and elevated sections.
Because the same Kato Unitrack system can grow with the layout, you can start small and add sidings, yards, new routes, or more mainline running without replacing the track you've already collected.
Kato Master Sets provide a convenient N Scale track foundation, while Variation Sets are designed to expand an existing Unitrack layout. Depending on the set, an addition can create a passing siding, switching area, extra loop, double-track section, viaduct, or another new route.
From there, individual straights, curves, turnouts, crossovers, and specialty pieces make it possible to move beyond a packaged track plan and build a layout around the space you actually have.
Track-only Master, Variation, oval, and expansion sets belong here. If a Kato package includes a locomotive and cars as a complete train, browse Kato N Train Sets instead.
A basic Kato N Unitrack loop can become a much more interesting railroad as switching and additional routes are added. #4 and #6 turnouts can create sidings and yards, while crossings and crossovers allow trains to move between routes and more complex track arrangements.
Kato's double-track and viaduct systems open up even more possibilities, including parallel mainlines, elevated running, and superelevated curves. These pieces are especially useful for layouts inspired by busy passenger corridors and modern mainline railroading.
When choosing curves and turnouts, consider the equipment you plan to run. Tighter-radius track can be useful for compact layouts, but not every N Scale locomotive or car is designed for every radius.
Kato Unitram takes N Scale track into the city. Instead of a conventional railroad roadbed, Unitram combines tram track with street-style roadway sections for building urban rail, streetcar, and tram scenes.
The system includes straight and curved street track, turnouts, crossings, feeder components, roadway sections, and other pieces for creating compact city routes. Kato also offers a connection between Unitram and Unitrack, allowing street-running trams and conventional Kato N Scale track to become part of the same larger layout.
Trainz inventory may include current Kato Unitram products alongside used, discontinued, and hard-to-find Unitram track, sets, and accessories.
Some of the most useful Kato track finds come from previously owned collections. Trainz inventory can include used Kato N Unitrack straights, curves, turnouts, crossovers, track sets, accessories, and assorted track lots alongside new products.
Assorted Kato Unitrack lots can be especially useful when you're expanding a layout and need a larger group of pieces rather than one specific section. Pre-owned inventory can also turn up older or discontinued track and accessories for an existing Kato N railroad.
When shopping used track, check the listing for the exact pieces included, radii, turnout types, connectors, and overall condition.

Kato N Scale Unitrack is a sectional track system with molded roadbed and removable UniJoiners for secure, reusable connections. It uses Code 80 rail and the standard 9 mm N Scale track gauge, making it suitable for everything from a simple loop to a large permanent layout. North American N Scale models are typically 1:160, while some Japanese N Scale equipment uses different modeling ratios while running on the same 9 mm gauge track.
Yes. Kato Unitrack is designed as an expandable system. You can add individual track pieces, turnouts, crossovers, double track, viaduct sections, and packaged expansion sets as the layout grows.
Master Sets provide a starting track configuration, while Variation Sets add features or additional routes to an existing Kato N Unitrack layout. Individual track pieces can then be used for further customization.
Yes. Kato N Unitrack can be used for analog or DCC layouts. The locomotives, controllers, turnouts, and other electrical components should still be checked individually for the type of operation you're planning.
Unitrack is Kato's conventional sectional railroad track with molded roadbed. Unitram is designed for tram and streetcar scenes, combining track with roadway-style sections for urban layouts. The two systems can be connected using appropriate Kato components.
Yes, when available. Trainz's changing pre-owned inventory may include individual Kato N Unitrack pieces, track sets, turnouts, accessories, Unitram components, assorted track lots, and discontinued items.
