Atlas HO Code 100 Plastic Insulating Rail Joiners – 6-Pack (144 Joiners) – ATL55

Atlas HO Code 100 Plastic Insulating Rail Joiners – 6-Pack (144 Joiners) – ATL55 provides a bulk supply of insulating rail joiners for electrically separating sections of HO scale Code 100 track. This package includes six individual Atlas 24-count packages for a total of 144 plastic insulating rail joiners, making it an excellent choice for larger layouts, extensive wiring projects and model railroaders who need multiple electrically isolated track sections.

Unlike standard metal rail joiners that mechanically connect adjoining rails while maintaining electrical continuity, these plastic insulating rail joiners mechanically connect the track while electrically isolating the two sections. They are useful for DC block control, DCC power districts, reversing sections, isolated sidings and other model railroad wiring applications where an electrical gap is required.

6 Packs – 144 Total Insulating Rail Joiners

ATL55 is supplied as six individual packages of Atlas Item #0055. Each individual Atlas package contains 24 Code 100 plastic insulating rail joiners, providing:

• 6 individual packages
• 24 insulating rail joiners per package
• 144 total insulating rail joiners

This larger quantity is particularly useful for modelers building or wiring larger HO scale layouts where numerous electrical gaps may be required throughout the railroad.

What Does an Insulating Rail Joiner Do?

A standard metal rail joiner connects adjoining rails while allowing electrical current to continue through the joint. A plastic insulating rail joiner mechanically connects the adjoining track sections while preventing electrical current from passing through the rail joint.

This creates an electrical gap between track sections, allowing different portions of a model railroad to be electrically isolated when required by the layout's wiring system.

Where Are Insulating Rail Joiners Used?

Atlas Code 100 insulating rail joiners can be used for a variety of model railroad electrical applications, including:

• Creating electrically isolated track blocks
• Separating power districts
• Isolating sidings and storage tracks
• Creating electrical gaps for reversing sections
• Separating independently powered track sections
• DC block-control wiring
• DCC layout wiring and power management
• Large layouts requiring numerous insulated rail gaps

Useful for DC Block Control

Traditional DC model railroad block control commonly divides a railroad into electrically isolated track sections. Insulating rail joiners provide a convenient way to create the electrical gaps required between these blocks.

Depending on the layout's wiring arrangement, individual blocks can then be powered or controlled independently, allowing multiple operating sections to be incorporated into the railroad.

Useful for DCC Layouts

Insulating rail joiners also have important applications on DCC model railroad layouts. Although DCC allows multiple locomotives to operate independently on the same electrical system, larger and more advanced layouts may still require electrically isolated sections.

Common applications can include separate power districts, booster districts, reversing sections and other specialized electrical arrangements. The exact location and number of insulating gaps required will depend on the layout's electrical design.

Plastic vs. Metal Rail Joiners

The primary difference between plastic insulating joiners and conventional metal rail joiners is electrical conductivity.

• Metal Rail Joiners: Mechanically connect adjoining rails while maintaining electrical continuity
• Plastic Insulating Rail Joiners: Mechanically connect adjoining track sections while interrupting electrical continuity

Because insulating joiners intentionally create an electrical break, they should be installed specifically where electrical isolation is required by the track plan and wiring system.

Designed for Atlas HO Code 100 Track

Atlas Item #0055 is designed specifically for HO Code 100 track. Code 100 rail measures approximately .100" high and is one of the most widely used rail sizes for HO scale model railroads.

These insulating joiners can be incorporated into Code 100 track arrangements wherever electrical isolation is required, including layouts using flex track, sectional track, turnouts and other compatible Code 100 track components.

Why Buy the 6-Pack?

With 144 total insulating rail joiners, ATL55 provides a substantial supply for modelers working on larger HO scale railroads or layouts requiring numerous electrical gaps. Rather than receiving a single 24-count package, this configuration includes six complete Atlas packages.

The larger quantity is particularly useful for extensive block-control systems, multiple power districts, yards, staging areas, club layouts and other projects where electrical isolation is required in numerous locations.
