The Lionel Extended Truss Bridge is a centerpiece accessory for O gauge model railroaders, offering both visual appeal and functional versatility. For hobbyists building elaborate layouts, the question of compatibility—whether this bridge works seamlessly with all track types—is paramount. In this comprehensive guide, we will explore every aspect of the Lionel Extended Truss Bridge's compatibility, examine its design features, and provide practical advice for integrating it into various track systems. We will also address common questions and troubleshooting tips to ensure your model railroad operates smoothly and looks spectacular.
The Lionel Extended Truss Bridge, especially the FasTrack version (SKU: 6-82110), is renowned for its detailed latticework, molded rivet details, and simulated wood decking. Spanning a full 30 inches, it is designed to be both a functional and aesthetic addition to O gauge layouts. The bridge can be used as a "lift out" section, providing access to walkways or hard-to-reach areas of your layout.
Track compatibility refers to the ability of a bridge or accessory to physically and electrically integrate with different types of model railroad track systems. For O gauge layouts, the primary track types include:
- Lionel FasTrack
- Lionel Tubular Track (O and O27)
- Other O gauge track systems from third-party manufacturers
Each track system has unique dimensions, connection methods, and electrical characteristics, which influence how accessories like bridges can be incorporated.
FasTrack is Lionel's modern, modular track system, featuring a plastic roadbed and easy snap-together connections. Its popularity stems from its durability, ease of use, and wide range of compatible accessories.
Tubular track is the classic Lionel track system, made of hollow metal rails and metal ties. It comes in O and O27 sizes, each with slightly different dimensions and curve radii.
Several manufacturers produce O gauge track compatible with Lionel trains, including Atlas O, MTH RealTrax, and GarGraves. These tracks may have different heights, rail profiles, and connection methods.
One of the standout features of the Lionel Extended Truss Bridge is its modular pier system. The piers can be stacked and configured to match the height of both FasTrack and tubular track trestles, ensuring a level transition across the bridge.
The bridge can be lifted off its piers, allowing for easy access to walkways or maintenance areas beneath the layout. This is especially useful in large, permanent setups where access can be challenging.
With intricate latticework, molded rivets, and simulated wood decking, the bridge adds realism and visual interest to any layout.
Spring steel contacts under each rail ensure a solid electrical connection as trains pass over the bridge, maintaining reliable power delivery.
The bridge is natively compatible with Lionel FasTrack. The track mounting top pier halves are designed to snap directly into FasTrack sections, accommodating both straight and curved pieces. This makes integration into a FasTrack-based layout straightforward.
To use the bridge with Lionel tubular track (O or O27), you need to use a FasTrack Transition Track (part number 6-12040, sold separately) at each end of the bridge. This transition piece connects the FasTrack on the bridge to the tubular track on your layout. The bridge piers can be stacked in a configuration that matches the height of tubular track elevated trestles, ensuring a smooth transition.
For other O gauge track systems, compatibility depends on the track's rail profile and connection method. In most cases, using the FasTrack Transition Track as an intermediary allows you to connect other brands' O gauge track to the bridge. However, some modifications or additional adapters may be necessary, depending on the specific track system.
Determine whether you are using FasTrack, tubular track, or another O gauge system. This will dictate which adapters or transition pieces you need.
- Unbox the bridge and identify the pier components.
- Stack the piers according to your track system:
- For FasTrack: Use the FasTrack elevated trestle section.
- For Tubular Track: Use the tubular track elevated trestle section.
- For tubular or other non-FasTrack systems, install the FasTrack Transition Track at each end of the bridge.
- Ensure the track sections align properly and are securely connected.
- Position the bridge on the piers.
- Use mounting tabs or screws to secure the piers to your layout base if desired.
- Run a test train across the bridge to ensure smooth operation and consistent power delivery.
- Check for any gaps or misalignments that could cause derailments.
If the bridge and your track are not at the same height, adjust the pier configuration by stacking the appropriate sections. The modular design allows for fine-tuning to achieve a level surface.
When using transition tracks, ensure all connections are tight and secure. Loose connections can lead to derailments or power loss.
If trains stall or lose power on the bridge, check the spring steel contacts under the rails and ensure the bridge is properly seated on the piers.
While the bridge is designed for straight sections, you can connect curved FasTrack pieces to the ends of the bridge using the track mounting top pier halves.
You can connect two or more Extended Truss Bridges to create longer spans. When doing so, use the bridge mating top pier halves as center supports and ensure all piers are of equal height.
The bridge's piers are designed to accommodate Lionel FasTrack Girder Bridges as approach sections. This adds visual variety and allows for creative layout designs.
If you run tall rolling stock, such as Husky stack cars or auto carriers, stack both FasTrack and tubular track elevated trestle sections to achieve maximum bridge height (up to 6.9 inches).
The Lionel Extended Truss Bridge is a versatile and visually striking addition to any O gauge model railroad. Its modular design and compatibility with both FasTrack and tubular track systems make it accessible for a wide range of layouts. While it is natively designed for Lionel's own track systems, with the appropriate transition tracks and adapters, it can also be integrated with other O gauge brands. Whether you are building a sprawling permanent layout or a compact temporary setup, the Extended Truss Bridge offers flexibility, realism, and reliability.
By understanding the bridge's features and following the recommended setup procedures, you can ensure seamless operation and enhance the visual appeal of your model railroad. For hobbyists seeking to push the boundaries of their layouts, the ability to connect multiple bridges, maximize clearance, and incorporate additional accessories opens up endless possibilities.
No special tools are required, but a small Phillips head screwdriver is helpful for securing the upper girder face plate and mounting the piers.
The bridge itself is a straight section and does not have a minimum curve radius. However, it can be connected to curved track sections at each end.
Yes, the bridge is designed to be easily lifted off its piers, making it ideal for use as a lift-out section over walkways or access points in your layout.
The bridge's modular design makes it suitable for both permanent and temporary layouts. It can be securely mounted or left as a removable section as needed.
Yes, replacement parts such as piers and screws are available through Lionel's support and parts service.
