O scale (or O gauge) is a scale commonly used for toy trains and model railroading. Originally introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s. In Europe, its popularity declined before World War II due to the introduction of smaller scales.
O gauge had its heyday when model railroads were considered toys, with more emphasis placed on cost, durability, and the ability to be easily handled and operated by pre-adult hands. Detail and realism were secondary concerns, at best. It remains a popular choice for hobbyists who enjoy running trains more than they enjoy other aspects of modelling, and collecting vintage O gauge trains is also popular - there is a market for reproduction and vintage style models also. A number of changes in recent years have addressed the concerns of scale model railroaders, making O scale more popular.
Conversely, in the United Kingdom O gauge is popular among fine-scale modellers generally with an emphasis on detail rather than operation. OO gauge, because of its low price and high availability, tends to be the most popular choice for those who wish to run their models. The size of O and OO layouts is also an important factor in decision making.
Famous quotes containing the word scale:
“I love to weigh, to settle, to gravitate toward that which most strongly and rightfully attracts me;Mnot hang by the beam of the scale and try to weigh less,—not suppose a case, but take the case that is; to travel the only path I can, and that on which no power can resist me. It affords me no satisfaction to commence to spring an arch before I have got a solid foundation.”
—Henry David Thoreau (1817–1862)
