Kits

Helix kits

A helix carries the track up or down in turns and links two levels on a small footprint. Ready-made kits come with deck sections and supports in fixed radii. This page lists their dimensions and the track systems whose curve radii match them.

In Trackplanner you plan the helix by radius, gradient and target height, and the helix assistant shows you kits that fit.

Dimensions as stated by the maker or retailer; for kits marked as research, from our own research. Radii are measured to the track centre; the gradient is the rise per turn divided by the circumference. A kit fits a track system when one of its curve radii is within 5 mm of the kit radius. A double-track kit needs one curve for the inner and one for the outer track. Where the maker names the track systems a kit is made for, only those count. Narrow-gauge systems such as HOe or HOm count too when a radius fits: the deck carries them as well.
