O Scale Model Trains
O scale and O-27 scale are a popular and widely available choice with model train hobbyists of all ages. O scale model trains have long been known for low cost, model durability, and ease of handling among model train hobbyists. In fact, many young model train enthusiasts began their hobby with an O scale railroad starter kit from Lionel, American Flyer, MTH, or other well known train set manufacturers.
O scale was invented around 1900 by the German toy manufacturer Marklin. These early toy model trains were centered more on play value than realism. The O scale quickly became a popular scale in model railroading. In fact, after the Great Depression in the United States, O scale model trains became the default model train standard. Early O scale track consisted of three rails. However, today the O scale is available in both two and three track configurations (the third, inside rail, is used for power). Over time, as hobbyists focused on realism and operations, HO scale and N scale model trains have surpassed the O scale in popularity. Yet the O scale remains a popular and widely used scale, particularly with starter sets.
What are O scale model trains? Scale refers to the ratio between model size and actual size. However, the actual scale varies slightly by region! In the United States, O scale model trains are 1:48 scale railroads. But in England, O scale is produced at 1:43.5 scale. And in Europe O scale represents yet another scale, 1:45. As a result, there is no common, consistent scale and gauge for all O scale model trains. So be aware of differences in compatibility when shopping for O scale model train equipment.
What do the variations such as O-27 scale represent? Actually there are several closely related O scale track options. If standard O scale model train track is laid out in a circle, the diameter is 31 inches. As a result, regular O scale model track is sometimes referred to as O-31 track. On the other hand, O-27 scale track forms a tighter, 27 inch diameter curve if laid out in a circle. The most common O scale track comes in a number of sizes, including O-27, O-31 (standard), O-42, O-54, and O-72 variations. Each variation refers to the diameter of the curve if laid out in a circle. One can get more track in a smaller space with the tighter curved track, but the tradeoff is realism and difficulty for some full-sized O cars to successfully negotiate the curves. However, the advantage of these options is that some hobbyists mix and match track to achieve their desired track layout.
While not as popular as HO scale N scale, O scale model trains have recently enjoyed increased popularity. As a result, many major manufacturers provide numerous O scale equipment options, including complete starter sets. Plus, the realism of O scale model trains has improved since the early 1990’s. Inconsistent O scale standards add to confusion with this scale. It’s important for hobbyists to be aware of regional differences in model scale coupled with two or three rail track configurations. Yet O scale and O-27 scale model trains remain a popular choice among hobbyists whose focus is on the simplicity and rewards of running model trains.
