HO Scale Atlas Code 100 Track Systems
Atlas Code 100 track has served as the foundation for countless HO scale model railroad layouts, offering a comprehensive system that combines reliable operation, authentic appearance, and excellent value. Code 100 refers to the rail height of 0.100 inches, representing the standard for HO scale track that accommodates all HO scale equipment including older locomotives and rolling stock with deeper wheel flanges. Atlas's nickel silver rail provides superior electrical conductivity compared to brass or steel alternatives, resists oxidation that can cause electrical pickup problems, and maintains consistent performance over years of operation. The comprehensive system includes everything needed to build complete layouts from simple ovals to complex multi-level operations, with components engineered to work together seamlessly for trouble-free construction and reliable long-term performance.
Understanding Code 100 Rail and Nickel Silver Construction
Code 100 rail measures 0.100 inches in height, making it one of the most versatile rail sizes for HO scale model railroading. This rail height accommodates virtually all HO scale equipment, from modern precision models to vintage locomotives with larger wheel flanges, ensuring broad compatibility across any collection. Nickel silver construction offers significant advantages over brass or steel rail, including superior electrical conductivity that improves locomotive performance, natural resistance to oxidation that maintains reliable electrical pickup over time, and the ability to accept soldering for power feeders and track modifications. These qualities make Code 100 nickel silver rail the practical choice for modelers building permanent layouts.
Flex Track for Custom Layout Design
Flex track represents the most versatile component in the Code 100 system, enabling modelers to create custom curves, easements, and transitions that sectional track alone cannot achieve. Nickel silver flex track can be curved to any radius from broad mainline curves to tight industrial sidings, and the molded plastic ties maintain proper rail gauge while allowing the flexibility needed for custom track arrangements. Flex track can be curved by hand without special tools, cut to exact lengths with rail nippers or a razor saw, and joined with standard rail joiners for seamless integration with sectional track components. This versatility makes flex track essential for creating realistic track arrangements that follow natural terrain and fit unique layout spaces.
Sectional Track: Straight and Curved Components
Sectional track components provide the building blocks for efficient layout construction, offering straight sections in multiple lengths and curved sections in various radii. Straight track sections come in several standard lengths, enabling efficient construction with minimal cutting and waste, while shorter sections allow precise spacing adjustments and fitting track into tight spaces. Curved track is available in multiple radii, from compact curves suitable for small layouts to broad mainline curves that enable smoother operation and more realistic appearance. Fractional curve sections allow precise curve fitting and custom track arrangements, giving modelers the flexibility to create complex track plans without extensive cutting or modification.
Turnouts and Switch Machines for Routing
Turnouts are essential components that enable trains to move between tracks, and Atlas offers multiple turnout configurations to suit different operational requirements. Turnout numbers indicate the diverging angle, with lower numbers providing sharper angles for compact layouts and higher numbers offering gentler, more prototypical diverging routes suitable for mainline operation. Manual turnouts provide economical operation with hand-thrown levers, while remote switch machines enable electrical operation from control panels or DCC systems for hands-free route control. Wye turnouts and curved turnouts expand the possibilities for complex track arrangements, allowing modelers to create realistic junctions and terminal operations.
Crossings and Bridges for Scenic Realism
Crossings enable complex track intersections at various angles, allowing modelers to create realistic junctions, diamond crossings, and grade-separated operations. Available in multiple angles from shallow crossings to 90-degree intersections, crossings provide the flexibility needed for virtually any track arrangement. Bridge kits add vertical interest and operational realism to layouts, with options including deck bridges, through truss bridges, and plate girder bridges in various railroad-specific paint schemes. These structures elevate track above scenery, creating dramatic visual elements while serving functional roles in multi-level layout design.
Track Accessories and Electrical Components
Essential track accessories include rail joiners for connecting track sections, terminal joiners for power connections, and rerailers that help guide derailed equipment back onto the track. Rail joiners come in plastic and metal varieties, with nickel silver joiners providing electrical continuity between sections and plastic joiners used for insulated gaps in block detection systems. Terminal tracks and terminal joiners enable power connections to transformers and DCC systems, while bumpers provide realistic end-of-track protection for sidings and stub-end tracks. Starter sets and track assortments offer convenient packages for new modelers beginning their first layout projects.
