Train Scales Explained

For those who are looking for a calm, relaxing hobby, model trains can be just the solution they’re looking for. However, when you first get started, the various scales can feel overwhelming. This guide will help you understand all of this information so you can make the best decision for your new hobby.

Scales vs. Gauges

The first question many people have is what the difference between a scale and a gauge is when it comes to model railroads. In most situations, you will deal with the term “scale.” This term refers to the size difference between the model train and real world trains. However, the term “gauge” references the space between the rails on the track. This second term is used in both model railroading and the world of full-size trains.

What Are the Different Scales?

One of the biggest challenges individuals have when they get started in model railroading is the variety of scales available on the market. While the size difference is evident when you look at the items in person, if you will be making a majority of your purchases online, it’s important to be knowledgeable in the differences.

G Scale: This is the largest of the scales and is often referred to as the Garden Scale because many people use this size for their outdoor layouts. These models are scaled between 1:22.5 and 1:29. This is often a good size for running around the Christmas tree. It is easy to operate, even for younger children, but takes up a lot more space than many of the other scales, which can pose a problem if you are limited on space.

O Scale: O Scale offers a scale of 1:48, making it smaller than the G Scale, but still larger than many of the others. This scale is ideal for operation by younger children, as well as older adults who may have difficulty manipulating smaller pieces. Trains of this scale are often pricier than the smaller trains and have a tendency to appear more toy-like in their operations and accessories.

O Scale, Narrow Gauge: This scale and gauge combination gives you the advantages of both O Scale and HO Scale trains. This is because you will still run the larger O Scale equipment, but on HO Scale track, allowing you to operate your train layout in a smaller space. This is ideal for those who love the look of the O Scale trains, but are more limited on space. It can be more difficult to find accessories that fit this size layout, however.

HO Scale: Perhaps one of the most popular modeling scale, HO gives you a variety of realistic options. This scale equates to 1:87.1, which makes it a great size for displaying and creating layouts of varying sizes, from the small to the large. With the vast array of accessories, track and rolling stock available, it’s easy to create a realistic layout with the right amount of time and effort. This size is perfect for teenagers and adults who are looking to invest significant time in their model railroading experience.

N Scale: If you are more limited on space, N Scale could be the ideal alternative, especially if you are still looking for that realistic look and feel to your railroad. However, the small size requires a stable hand and attention to detail. While options may be limited, this scale is growing in popularity, which means manufacturers will be creating more in the near future.

There are a few additional scales, many of which are smaller yet, such as the S Scale and Z Scale. However, the options for these sizes are extremely limited due to a lack of popularity.

Why Are There So Many Scales?

As noted above, there are a variety of scales to help individuals find the option that best suits their needs. The larger scales are perfect for unique applications like for use outdoors around the yard or for placing around the Christmas tree for that holiday feel. They are also better for use with younger children. However, if you are looking for a more realistic look with greater attention to detail, the smaller scales are the perfect solution.

What Is the Best Model Train Scale?

This is a personal question depending on a variety of factors. First and foremost, you need to consider the age of the individuals who will be using the trains. Larger scales are best for young children and older individuals who have dexterity or vision issues, for instance. You will also need to consider the amount of space you have available. You can do far more with smaller scales in a small space than with larger scales. Setting a budget is also important. Certain scales can cost more than others. For instance, O Scale is significantly more expensive than HO Scale. However, it also depends on the amount of work you will put into your layout. Once you buy a lot of accessories, you will find the costs often even out. Finally, you need to think about what you want to accomplish. If you’re just looking to play with the trains, a larger scale can be perfect. However, if you want a more detailed, permanent layout, the smaller scales will offer a greater selection of products and improved customization, giving you more freedom of design.

Can You Mix Scales?

In general terms, it isn’t advised to mix scales. For the most part, you won’t be able to buy track in one scale and use another scale train on those tracks. In these terms, you will need to stick to the same scale. However, there are situations in which mixing scales in your layout can produce the effects you’re looking for. If you have the attention to detail required, you will be able to implement some smaller scale pieces to add some depth and perspective to your layout. Adding these pieces will require a careful eye to avoid making things look awkward and out of place in your layout. However, if you are looking to keep things simple, it’s best to work with the same scale.

While it can be overwhelming to shop for pieces to your train layout at first, learning as much as you can about what the different scales mean can help you make the best decisions for your situation.
