3-Rail Scale Model Trains
3-Rail Scale is an approach to model railroading in O scale that strives to achieve the most true-to-prototype realism possible with locomotives, rolling stock, paint schemes, scenery, operation, and other aspects of the hobby, while still using 3-rail O gauge track. This would include the use of scale (Kadee) couplers, and other modifications that make the model as close to prototypical as possible. The intent is to get as close to the prototype as you can in your pursuit of the hobby with the talents you possess.
3-Rail Scale is an approach to the O gauge hobby that derives satisfaction and enjoyment from using the prototype as its guide. Model railroaders who choose to model in 3-Rail Scale strive for as much prototype realism as possible within the limitations of time, talent, and space.
