Build an HO Layout Around Kato Unitrack

Kato HO Unitrack gives HO modelers a sectional track system with molded roadbed, Code 83 rail, and removable UniJoiners. Pieces connect in a consistent geometry, making it straightforward to test a track plan, build a complete railroad, or keep expanding an existing layout.

Code 83 Rail

Kato HO Unitrack uses Code 83 rail for a lower rail profile than traditional Code 100 HO track.

Integrated Roadbed

The molded roadbed is built into each track section, so the track has a finished base without requiring separate roadbed.

Removable UniJoiners

UniJoiners align adjoining sections, carry electrical power, and can be replaced when needed.

For shoppers, that means HO Kato Unitrack can work just as well when you're buying an entire track set as when you're hunting for one turnout, curve, feeder, or replacement section to finish the railroad.

Find the Right Track Piece for the Plan

HO layouts often grow one decision at a time. A new turnout can create an industry or passing siding, broader curves can reshape a mainline, and crossings or specialty pieces can solve a particular track-planning problem.

Depending on inventory, Kato HO track may include straight sections, curved track, turnouts and switches, crossings, crossovers, feeder sections, rerailers, track sets, and other Unitrack components.

When adding to an existing layout, check the Kato item number, track length, curve radius, turnout direction, and geometry rather than assuming two similar-looking sections are interchangeable.

Code 83, DCC & Connecting HO Unitrack

Kato HO Unitrack uses Code 83 nickel-silver rail, with a rail height of approximately 0.083 inches. That makes rail code an important detail when you're planning a transition between Kato track and another HO track system.

HO Unitrack can be used for conventional DC or DCC operation. The track itself carries either system, while turnout controls, feeders, decoders, and other electrical components should be chosen for the way the railroad is wired.

Because UniJoiners are removable, Kato HO Unitrack can also be incorporated into layouts using other compatible HO track. At the transition, pay attention to rail height, roadbed height, alignment, and how the rails are joined.

New, Used & Discontinued Kato HO Unitrack

Finding the exact track section can matter more than whether it is from the newest production run. Trainz inventory can include new Kato HO Unitrack alongside used, pre-owned, discontinued, and hard-to-find track from previously owned collections.

That can be especially useful when you're matching an established layout, replacing a damaged turnout, or looking for an older track component that is no longer easy to find new. Assorted HO Unitrack lots can also be a practical way to add a larger group of straights, curves, and other pieces at once.

For pre-owned track, review the quantity, geometry, UniJoiners, electrical components, and overall condition shown in the listing.
