Track Components and Geometry

Track spacing (parallel track distance)

Track spacing between reference and parallel track

Track spacing is the distance between the centrelines of two parallel tracks. Every track system has a standard spacing (in H0 e.g. 61.9 mm for Piko A, 76.5 mm for Roco geoLine, 77.5 mm for Märklin C track) that turnouts, curve radii and crossings are designed around. Sufficient spacing matters so long vehicles do not touch in curves.
