BGT Episode 3: Scale and Gauge

Okay, confession, for as long as I've been in the hobby, it has always driven me nuts when someone says "I model in O Gauge". No. Ultra no. Infinity no. Gauge is the distance between the rails, scale is how small the trains are with respect to the prototype. Several scales use the same gauge track to represent alternate gauges of that scale. For example, F scale uses G gauge track to represent 3ft narrow gauge, and On30 uses HO gauge track to model 30 inch narrow gauge, whereas both G and HO use their respective gauges to represent standard gauge. Thus, saying which gauge you model in can be very uninformative as to what you do with it. Hopefully, this episode will eliminate such confusion in the next generation of modelers.
