Getting wheel spacing and track geometry right can make a noticeable difference to the reliability of a model railway, and Layout Concepts offers a useful selection of precision gauges for modellers working across several scales and standards. The range includes back-to-back gauges for N, TT/HOn3, Sn3/HOn3.5, standard OO/HO, fine OO/HO and P4, allowing wheelsets to be checked and adjusted to the appropriate spacing. The standard OO/HO gauge is set at 14.5mm, with 14.75mm and 14.85mm options available for finer wheel standards, while the P4 version is designed for a 17.75mm back-to-back measurement.
For modellers building or fine-tuning their own track, the range also includes specialist track-making tools. The OO/HO three-point track gauge is designed for fine 16.5mm track and helps maintain accurate rail spacing when constructing pointwork, while the fine flat-bottom roller gauges are suitable for Code 70, 75 and 83 rail with tighter flangeway standards. Manufactured in brass and designed to give consistent measurements during layout construction and maintenance, these Layout Concepts tools are practical additions to the modeller’s workbench where reliable running and accurate trackwork are the priority.
