Product Description
Track gauge for code 70 rail at a gauge of 19.0mm. This is the gauge used for On3, which models 3' gauge railways in 1:48 scale.
Designed to work with Micro Engineering code 70 rail or any other rail that has the code 70 railhead width of 0.035" as specified in NMRA recommended practice RP-15.
The gauge has four prongs to hold the rails parallel for ease of laying track. The prongs are placed more widely apart on one side to spread the gauge slightly on curves. The widely-spaced prongs go on the outside of the curve.
