How to Use Two Bachmann Train Sets Together


If you are a model train enthusiast, you might have wondered if it is possible to combine two Bachmann train sets to create a larger layout. The good news is that it is entirely possible, and this guide will show you how to do it step-by-step.


Combining two Bachmann train sets can give you more tracks, trains, and accessories to play with. It can also allow you to create a more complex and realistic layout, complete with bridges, tunnels, and landscapes. However, it requires careful planning and execution to ensure that the two sets work seamlessly together.

Choosing the Right Bachmann Train Sets

The first step in using two Bachmann train sets together is to choose the right sets. Ideally, you should select two sets that have the same scale, gauge, and control system. It will ensure that the trains run smoothly and do not derail or crash.

Bachmann offers a wide range of train sets, including N scale, HO scale, and O scale. Each scale has different proportions and dimensions, so make sure to choose two sets that match each other.

Planning the Layout

Before connecting the tracks, you should plan the layout of your combined Bachmann train sets. It involves deciding on the shape, size, and features of your track, such as straight sections, curves, turns, and inclines. You should also consider the location of the power source and control system.

You can use software programs, such as AnyRail or SCARM, to create a virtual model of your layout and experiment with different designs. Alternatively, you can draw a rough sketch on paper and use it as a guide.

Connecting the Tracks

Once you have planned the layout, it is time to connect the tracks of the two Bachmann train sets. You should begin by laying out the tracks on a flat surface, such as a table or a plywood board. Make sure to align the tracks properly and use rail joiners to connect them securely.

If the two sets have different rail heights or joiner types, you might need to use adapters or shims to make them compatible. You should also consider using expansion tracks, turnouts, and crossovers to add more variety and flexibility to your layout.

Wiring the Sets Together

After connecting the tracks, you need to wire the two Bachmann train sets together. It involves connecting the power supply, control system, and accessories of both sets using wires and connectors. You should refer to the user manuals of the sets and follow the instructions carefully.

In general, you need to connect the positive and negative terminals of the power supply to the track power input of the control system. You should also connect the accessories, such as lights, signals, and switches, to the corresponding output terminals of the control system.

Testing the Connection

Once you have wired the two Bachmann train sets together, you should test the connection to ensure that everything works as intended. You should turn on the power supply and control system and run the trains along the tracks.

If you notice any issues, such as slow speed, jerky movement, or derailment, you should troubleshoot them by adjusting the track alignment, cleaning the tracks, or checking the wiring. You might also need to fine-tune the speed and direction of the trains using the control system.

Adding Accessories and Landscaping

After testing the connection, you can add accessories and landscaping to your combined Bachmann train sets. You can use a variety of accessories, such as buildings, figures, vehicles, and scenery items, to create a realistic and immersive environment.

Bachmann offers a wide range of accessories that are compatible with their train sets, such as trackside structures, people, animals, and trees. You can also use generic accessories from other manufacturers or make your own using simple materials, such as cardboard, foam, and paint.

When adding landscaping, you should consider the scale and theme of your layout. For example, if you have an HO scale layout, you should use 1:87 scale scenery items that match the era and location of your trains. You can also use landscaping techniques, such as adding hills, valleys, and water features, to create a more dynamic and appealing layout.

Troubleshooting Common Issues

While using two Bachmann train sets together can be a fun and rewarding experience, it can also come with some challenges and issues. Some of the most common issues include:

  • Poor track alignment or connection
  • Dirty or corroded tracks
  • Incompatible wiring or control systems
  • Overloading the power supply
  • Derailments or collisions

To troubleshoot these issues, you should follow the user manuals of the train sets and accessories and use common sense. For example, you should clean the tracks regularly using a track cleaner or rubbing alcohol and avoid using too many accessories that can overload the power supply.

Maintaining Your Bachmann Train Sets

To ensure that your Bachmann train sets continue to run smoothly and look great, you should maintain them regularly. This includes cleaning the tracks and wheels, lubricating the moving parts, checking the wiring and connections, and storing them properly.

You should also avoid exposing your train sets to extreme temperatures, moisture, dust, or sunlight, as they can damage the components and the paint. Instead, you should store them in a dry and cool place, such as a closet or a garage.


Combining two Bachmann train sets can be a fun and challenging project that can enhance your model train experience. By choosing the right sets, planning the layout, connecting the tracks, wiring the sets together, testing the connection, adding accessories and landscaping, troubleshooting common issues, and maintaining your sets, you can create a stunning and realistic layout that will impress your friends and family.
