Eishindo's track products includes two types. Sectional track with integrated roadbed is available in three colors (wood ties, concrete ties, and transparent), with four curve radii and three straight-track lengths. Switches are manual; two crossings are due early 2011.

In addition, flex track is offered in two styles (concrete or wood ties/sleepers) and two lengths (200mm and 1m). Flex does not have roadbed (although roadbed is available from TGauge.co.uk). Sections are joined with short joiner parts. Flex-to-roadbed transition tracks are available in two styles.
