Gauges and Scales
by Ivan W. Baugh
Gauge is the distance between the inside of the outermost rail heads. The gauge for most of the railroads in the world is 4' 8.5" between the inside of the outermost rail heads.
Scale refers to the ratio between the actual size (prototype-a railroad you would see at a highway crossing) and the modeled size. Scale compares inches or millimeters with feet of the prototype.
