S guage?

[Anonymous]

Sorry, confused. What is larger, S or O guage?

Ah, a simple question with not such a simple answer. Scale is defined as a ratio of prototype to model being 1:64. O scale is 1:48. Gauge, which is the distance between the railheads, is a bit more complicated. Depending on the prototype, any of several gauges may be represented in any of the modeling scales. For example, there is Sn3, which has a scale distance of 3 feet between the railheads. And just plain old S scale has a scale distance of 4 feet, 8.5 inches between the railheads. With both models, one foot is still equal to 1/64th of an actual foot, but the Sn3 track is narrower (and the model is usually smaller) than the S scale track. The same applies for O scale, whether you're talking about On2-1/2, On3, or just plain O scale. Scale is what determines a model's relationship to the real world in terms of its size.
However, the simple answer to your question is O scale is larger than S scale.

Sorry, the second sentence should read "S scale is defined as a ratio of prototype to model being 1:64." It's been a long day.
