Two-rail

A system in which both rails carry current, each at a different pole. The wheels on each side are therefore insulated from each other.

Dutch

tweerail

German

Zweileiter

Example

Trix C track is the two-rail DC version of C track with the same dimensions: turnout 62611 with compensating curve 62224 also gives 77.5 mm.
