Are Model Train Tracks Universal?

If you’re a collector of model train tracks, you might be wondering if they are universal. After all, it’s best to be prepared before you start laying out your railroad tracks or purchasing more.

As a general rule, not all model train tracks are universally compatible even though they may share similar rail connections. While standard tracks are typically interchangeable within their gauge, not all integrated roadbed tracks are designed to fit together.

Before buying new tracks, it’s important to know what you’re getting into. From metals used to track codes to rail connections, there is a lot to take into account before laying out a track. Below, you will learn if model train tracks are universal, and how to find the best tracks to use for your railroad.

Are Model Train Tracks Interchangeable?

If you are just starting out with model trains, you may be confused about which tracks to choose from. Can you use model train tracks from different brands or are you stuck using just one? What about the different codes and track materials?

Unfortunately, it’s not safe to assume that all model train tracks are universal. There are some common standards that many manufacturers follow, but this isn’t the case for everyone.

While you might be able to use some of your tracks interchangeably, others won’t fit together quite as easily. The key here is to know which ones can be used together and which ones can’t.

What is Track?

Commercial model train tracks typically consist of ties and rails that are fastened together in sectional pieces. Sometimes, this can also include the roadbed beneath the track as part of the structure, which is known as roadbed track or prefab track.

The type of track you choose can impact how universal it is, so it’s important to have a clear understanding of each one and its advantages before purchasing your first track.

Standard Tracks vs Roadbed Tracks

Standard tracks include the rails and ties and provide the most versatility when it comes to laying your track. As long as the rails are the same size, most brands are considered compatible with each other.

Standard track also includes flex track, which allows you to bend that track however you may need. This allows hobbyists to mix and match rails, giving the most freedom for creativity.

On the flipside, roadbed tracks typically include the roadbed as part of the structure. One advantage of roadbed tracks is that they are easy to set up and take apart, and do not require a separate roadbed.

However, because each brand uses different connectors, these tracks are not universal and cannot be used with each other. This can be limiting for those who are trying to expand their tracks. Atlas, Bachmann, Kato are three of the main manufacturers of roadbed tracks.

Can Standard Track and Roadbed Track Be Used Together?

Due to the specific connectors that each manufacturer uses and the fact the roadbed is included in the track’s structure, roadbed tracks cannot be used interchangeably with standard tracks.

Roadbed track is the best option for beginners who are building a track for the first time. Once you have more experience with tracks, it is then a good idea to switch to standard tracks, which can be used more universally across brands.

Can Different Track Scales Be Used Universally?

One of the most important decisions you’ll need to make when picking out your model train track is the scale. Scale codes are defined by the NMRA as the size of the train model in relation to the real things.

These sizes include:

  • Z
  • N
  • HO
  • S
  • O
  • G

These are the industry-standard labels that nearly all manufacturers use to describe their products.

Different scales of model trains are not universal, so it’s important to choose your scale carefully. Some sizes are more popular than others, which means you will have more product options and better luck finding tracks and trains to add to your collection.

HO is considered the most popular scale size, with N coming in a close second.

Are Train Track Gauges Universal?

Just like real-world train tracks, model train tracks have different gauges. While many people will use the terms scale and gauge interchangeably, the gauge actually refers to the distance between the rails of the track.

The two gauges you will see are a standard gauge and a narrow gauge. Standard gauge is 4’ 8.5” between the rails. Narrow gauges can vary, but you will typically see either a two-foot gauge or a three-foot gauge.

Because the gauges have different distances between them, narrow and standard gauged tracks cannot be used interchangeably. In fact, it’s important to know what your gauge is, so that you can avoid any issues that your tracks fitting together or your train fitting on your track.

Are Model Train Track Rail Metals Interchangeable?

When it comes to the metal type of your track, nickel silver is typically the best choice. However, if you have some brass or steel rails lying around, you might be wondering if it’s acceptable to use them together.

As a general rule, as long as you can achieve a good connection at the flange faces and the tops of the rails, there should not be an issue using brass and nickel silver model train tracks together.

However, brass and steel tend to oxidize, so maintenance could become an issue. These metals require more frequent cleanings, while nickel silver does not. Nickel also more closely resembles steels, so using them together may impact the overall look of your track.

Final Thoughts

Hopefully, this article gave you some insight into which model train tracks are universal. If you’re a new hobbyist, picking a good and reliable track is an important first step in model trains. Not only will you want something that matches your experience level, but you’ll want to choose a track that you can easily obtain pieces for, or easily match it with other brands on the market so that you track in operational for years to come.
