Kato UniTrack N

Check for updates

Kato UniTrack N gauge track is probably the most widely used two-rail track with integral ballast for N gauge. It is simlar in design and concept to Kato UniTrack HO gauge. Kato track is compatible with that of other manufactuers such as Atlas , Fleischmann, MiniTRIX, andPeco through use of an adapter section. The table and image below show the components in the RR-Track Kato N track library.

Currently, Kato offers UniTrack in 7 radii, with an 8th radius (R718) used mainly as a parallel curve for the #6 turnout.

The Kato UnitTrack N  library now contains a track wizard which is capable of using the fixed size straight and curved track sections to fill most gaps encountered in layout design.   This wizard is only available for RR-Track v5.1 systems build and above ( Update Pack 4 ). 

Items in red are newly added. The current v5 library release is 4.90.017. If yours is less than this, please go to our updates page to download a new copy.
