Code 332 (0.332" high) solid rails of pure, virgin brass for excellent electrical conductivity. Ties of ultra-violet stabilized HDPE (High density polyethylene) for decades of outdoor use. Unique track geometry makes even complex track plans simple to build with only a few types of track sections. Compatible with most other makes of  G-Scale track, such as LGB and Aristo-Craft , for unlimited expansion possibilities. Through the sophisticated geometry of PIKO G-Track, one can easily make layouts with transitions to all curve radii, using the standard switches. PIKO G-Track is (As LGB Track) patterned after 1000mm narrow-gauge track.
