NMRA Standards/Guages

NMRA standards provide the primary basis upon which Interchange between equipment and various North American scale model railroads is founded.

Model train gauges with the NMRA standards provide model railroaders a way to check all important dimensions of a track and rolling stock as follows:

  • Gauge of track and turnouts
  • Flangeway depth and "check gauge"
  • Clearance
  • Height of loading platform 

If cars do not run correctly, these NRMA gauges will help you pinpoint the trouble.

The pocket size model train gauge is a railroad tool that should be in every serious modeler's kit.
