Clearance Gauge Modern Era

The NMRA's "RP-7 Track Centers and Obstacle Clearances" defines the standard for clearing bridges, structures, and tangent tracks. These apply to four distinct eras, namely Old Time era (pre-1920; can also be used for narrow-gauge track), Classic era (1920-1969), Early Modern era (1969-1983), and Modern era (post-1983). This version is for the Modern era. The clearance gauge is a tool to assist in building S-scale model train layouts, modules, and dioramas. Wherever track passes by a bridge, tunnel, structure, trackside object, or equipment on an adjacent track, the gauge can verify that rolling stock will be able to move unobstructed. It is not intended to be used as a gauge for building track work itself; just for positioning surrounding items alongside track. The gauge comes with an instruction sheet that tells you more about the standard, the gauge, and how to use the gauge on your layout, module, or diorama. The gauge was developed by the Southeastern Michigan S Gaugers club, and are made available through the NASG. We do not have gauges for the Old Time and Early Modern eras, but contact us if you are in need of those.
