HO Scale trains lead the pack with 31% of total searches in the US compared to 30% of searches for O Scale trains. HO Scale also leads the pack globally with a dominant 49% of searches. The explanation for the popularity of HO scale trains is due more to the affordable prices and manageable size. HO scale trains are 1:87 scale, which means the cars are about 7-9 inches long. HO scale trains are about the right size for most beginner train hobbyists because the track layout usually fits well on a 4 x 8 piece of plywood.

Compare that to O scale model trains, which are 1:48 scale, which means the cars are about 12-16 inches long. Not only do O scale train sets take a lot more space to set up and to store, they also cost a lot more. As a result, the O scale trains are primarily purchased by more serious model trains hobbyists while the HO scale trains are primarily purchased by beginners and families looking for train sets as a Christmas gift.

The next leading scales are the N scale model trains with 20% of searches, followed by G scale with 16% of searches. N scale trains are 1:160 scale, which makes them even smaller than HO trains. Cars are only about 4-5 inches long for N scale. G scale trains are at the other end of the size spectrum with 1:22.5 scale, which means the cars are about 18-26 inches. G scale trains are too big to fit in most homes. They are most commonly used in outdoor gardens.

The only other scales getting any searches are Z scale and S scale. Z scale received 3% of total searches while S scale received less than 1%. Z scale trains are 1:220 scale, which is even smaller than N scale. Z scale is a popular choice for people who have only a very small space available such as a coffee table or a desktop. S scale trains are 1:64 scale , which is slightly larger than the popular HO scale and slightly smaller than the popular O scale. Despite being in the same size range as the two most popular scales, the S scale trains have not caught on for many hobbyists.

Let’s start with scale. Model trains are scaled down trains–that is, smaller versions of real trains. A model train’s scale tells us its proportion in relation to the real train version. For example, a Lionel train is an O27 train, with a scale of 1:48 . This means that the Lionel train is 48 times smaller than its real train counterpart, with one-quarter inch equal to one scale foot. Due to their larger size, Lionel trains are easy to work with, especially for beginners.

Gauge–gauge is the distance between the rails of a railroad track. Standard track gauge is 4’ 8.5”. O gauge tracks are 1.25” apart. Something to be aware of, though, is that gauge and class specifications can vary internationally, so always check the exact measurements before buying internationally.

As O27 trains, Lionel trains are a bit different from standard O gauge trains. They run on O27 track, which is a bit shorter and narrower than standard O track. The difference can be seen when O27 track is laid out in a circle–an 8 piece circle of O27 track will be 27” across (an 8 piece circle of standard O track is 31” across). Love Lionel trains but have a lot of O track from other set-ups? That’s okay because you can use O track and O27 track together without any problem. Raise your track a little by using a shim, widely available at hobby shops.

Some companies, like Conrad, NZG, and Corgi manufacture die-cast, or metal, model trains that are also compatible with O scale track. This can lead to some interesting track set-ups, and die-cast trucks, cars, buses and construction equipment are popular with collectors.

Lionel trains are a good choice for many reasons. Beyond the ease of running an O27 train, they are also great for modelers looking to perfect model and replica trains. Their size is easy to work with (unlike the smaller N and Z gauge trains), and a great choice for children interested in railroading.

First things first, let’s define scale as it’s used in reference to model railroads: Scale is the proportion to an actual size train or its prototype; the smaller the scale, the more you can fit into your allocated model train area.

G Scale – 1:22.5 – G scale is most often used in garden layouts and is sometimes referred to as an LGB scale. It’s ideal for those who appreciate gardening and landscaping.

O Scale – 1:48 – Although similar to the O27 scale, there are a few differences which we’ll outline below. If your goal is to keep the proportions as realistic as possible, you should consider a large area to build around this scale. The trains are bigger than all other scales except for G scale, and incorporate DC currents.

O27 Scale – 1:48 – Similar to O scale, O27 is differentiated by the curves in the tracks. The O 27′s area is a 27″ arc or circle while the standard O Scale will encompass 31″. Another significant difference is the 27′s shorter and thinner rails. This is a particularly popular scale since there are so many accessories available that are life like and have working parts.

S Scale – 1:64 – It’s been said the S scale isn’t quite as popular as many of the others; however, many of us are sentimental and are drawn to this particular scale since it’s what we’re most familiar with from our childhoods.

HO Scale – 1:87 – Another popular scale, the HO is 1/87th in terms of comparison to the real thing. Its size is considered ideal and easily works on standard plywood sizes. This is another scale that offers a lot in accessories.

TT Scale – 1:120 – Many tend to avoid this scale simply because suppliers of accessories aren’t plentiful.

N Scale – 1:160 – Not the smallest scale, but very close. That said, it’s a popular scale for model toys since it’s perfect for those with limited space. Its size is half of what the HO offers. Like long curves and a lot of scenery? This might be your best
option.

Z Scale – 1:120 – This is the smallest sized trains, but ideal for really tight spaces or smaller bedrooms. Another strong point the Z scale brings to the table is its ease of transportation.

With just a little consideration and thought about how you intend to incorporate your model railroad into the available space, you can easily choose the best scale for your needs.
