Kato Unitrack is a large and varied range manufactured in Tokyo Japan. It features non-adjustable fixed length/ radius track pieces, with a pre-formed and pre-modelled track bed.

The range is almost entirely made up of Code 80 N Gauge rails, except for a smaller range of Code 83 HO Rails, listed in its own seperate section above.

Unitrack features highly durable track joiners that feature a soft plastic chair that house the metal fishplate and ensure secure joints when clipped or unclipped together. This makes it one of the best "set and and pack up" systems.
