Model Train Scale Explained
Having the right scale size is essential when building a model train. The most desirable model trains can become basically worthless without the proper scale size. That’s why it’s so important to properly educate yourself before settling on a model train scale.
Questions to consider when choosing a train scale size
- Are you planning on an indoor track layout, or maybe outside?
- Do you plan on staying with the hobby for years to come?
- Will you be sharing or passing on this tradition with someone?
- What’s you (yearly) budget for model training?
The most popular and commonly used train scale is the HO. These have an approximate ratio to the original train of 1:87. One of the reasons that this scale is so popular is because it is large enough for an impressive display and it doesn’t involve any intricate or complicated work when creating the layouts. Because the HO is u
sed by so many people, it is hands down the easiest to get a hold of.
The N model scale is considered to be second in popularity to the HO. This train scale is approximately 1:160. The distance between the inside rails in the track or this scale is nine millimeters. The N scale can be considered to be a bit more practical than the HO because it is so much smaller and therefore requires a lot less space to construct and maintain. However there is a major disadvantage is choosing the N scale. The small size that this model scale comes in makes accessorizing it quite difficult.
There are three remaining scale sizes that are considered to be more popular than the rest. The first is the O model train. This one has an approximated ration of 1:48. These are among the larger types of model scales and require a great deal more space. The next popular model scale is the G scale, which is about 1:24. Because these scale model trains are drastically larger than even the O scale, they are usually used outdoors and make a great additional feature to gardens and landscapes. Lastly, we have the Z train. With a ratio of 1:220, this is hands down the smallest of the five popular scales. Z scales obviously require very little space and can be used anywhere. Hobbyists who have poor eyesight, or large hands can have difficulty accessorizing this model and therefore tend to avoid using the Z train.
Each of these five model train scales are very easy to get a hold of. With a decent knowledge of these scales, you’ll find it much easier to determine which scale would be best suited for you.
