Model Railroading Scales and Sizes
Model railroading offers a variety of scales and sizes to suit different preferences and available space. Here are some of the most popular scales used in model railroading:
1. Z Scale: Z scale is the smallest commercially available scale, with a ratio of 1:220. It is known for its tiny size and is suitable for those with limited space. Z scale trains are approximately 1.9 inches (48 mm) long.
2. N Scale: N scale is another small scale, with a ratio of 1:160. N scale trains are about half the size of HO scale trains, making them popular for modelers with space constraints. N scale trains are approximately 3.5 inches (88.9 mm) long.
3. HO Scale: HO scale is the most popular scale worldwide, with a ratio of 1:87. HO scale trains are about half the size of O scale trains, making them versatile and widely available. HO scale trains are approximately 6 inches (152.4 mm) long.
4. O Scale: O scale is a larger scale with a ratio of 1:48. O scale trains are popular for their level of detail and are often favored by collectors. O scale trains are approximately 12 inches (304.8 mm) long.
5. G Scale: G scale, also known as garden scale or garden railway, has a ratio of 1:22.5. It is the largest commercially available scale and is often used for outdoor layouts. G scale trains are approximately 24 inches (609.6 mm) long.
6. TT Scale: TT scale is less common but still has a dedicated following. It has a ratio of 1:120, falling between HO scale and N scale in size. TT scale trains are approximately 4.5 inches (114.3 mm) long.
7. S Scale: S scale is larger than HO scale and has a ratio of 1:64. It is known for its compatibility with American Flyer trains. S scale trains are approximately 8 inches (203.2 mm) long.
8. O27 Scale: O27 scale is a variant of O scale and has a ratio of 1:48. It is designed to operate on tighter curves with a radius of 27 inches. O27 scale trains are the same size as O scale but can negotiate smaller layouts.
These scales represent the most widely used options in model railroading, but there are also other less common scales available, such as On30 (O scale models running on HO scale track) and Sn3 (narrow gauge scale with a ratio of 1:64). The choice of scale depends on factors such as available space, desired level of detail, and personal preference.
