HO Scale Atlas Code 100

Complete HO Scale Atlas Code 100 Track System

Atlas Code 100 track has served as the foundation for countless HO scale layouts since its introduction, offering modelers 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 deep wheel flanges. Atlas's nickel silver rail provides superior electrical conductivity compared to brass or steel rail, resists oxidation that causes electrical pickup problems, maintains consistent performance over years of operation, and accepts soldering for power feeders and track modifications. The comprehensive product line 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.

Super Flex Track: Layout Building Foundation

Atlas Super Flex track represents the most versatile component in the Code 100 system, enabling modelers to create custom curves, easements, and transitions that sectional track cannot achieve. The 36" Super Flex Track (1 Pcs) provides individual pieces for small projects or specific applications, while the 36" Super Flex Track (5 Pcs) offers economical bulk packaging for larger layouts. Super Flex track features nickel silver rail that can be curved to any radius from broad mainline curves to tight industrial sidings, molded plastic ties that maintain proper rail gauge while allowing flexibility, and pre-weathered tie color that eliminates the toy-like appearance of bright plastic. The 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.

Straight Track Sections

Atlas offers straight track in multiple lengths enabling efficient layout construction with minimal cutting and waste. The 9" Straight Track (6) and 9" Straight Track (1 Pcs) provide the most common straight section length, ideal for yard tracks, sidings, and mainline runs. Shorter sections include 6" Straight Track (4), 3" Straight Track (4), and 1 1/2" Straight Track (4) for precise spacing adjustments and fitting track into tight spaces. These shorter sections eliminate the need to cut flex track for minor length adjustments, saving time and reducing waste.

Curved Track: Multiple Radius Options

Atlas Code 100 curved track comes in multiple radii accommodating different layout sizes and operational requirements. The 15" Radius Track (6) and 15" Radius Track represent the minimum radius for most HO scale equipment, suitable for compact layouts and tight spaces. The 18" Radius Track (6) and 18" Radius Track provide the most popular curve radius, offering good operation with most equipment while conserving space. Broader curves include 22" Radius Track (6), 22" Radius Track, and 24" Radius Curve (6) enabling smoother operation and more realistic appearance. Fractional curves including 1/2 18" Radius Track (4) and 1/3 18" Radius Track (4) allow precise curve fitting and custom track arrangements.

Turnouts: Mark IV and Mark V Systems

Atlas offers two turnout systems providing different levels of realism and operational characteristics. Mark IV turnouts feature simplified construction with manual or remote operation, reliable performance, and economical pricing. The #8 Mark IV Turnout Left and #8 Mark IV Turnout Right provide gentle diverging angles suitable for mainline operation. Mark V turnouts represent Atlas's premium line with enhanced detail, more realistic frog and point construction, and smoother operation. Options include #4 Mark V Turnout Left, #4 Mark V Turnout Right, #6 Mark V Turnout Left, and #6 Mark V Turnout Right. The Mark V Wye Turnout enables wye track configurations, while CustomLine Curved Turnout - Left and CustomLine Curved Turnout - Right allow turnouts in curved track sections.

Snap Switches: Integrated Turnout Systems

Atlas Snap Switches combine turnouts with integrated switch machines in ready-to-install packages. Manual versions include Manual Snap Switch Left and Manual Snap Switch Right with manual throw levers. Remote versions feature Remote Snap Switch Left and Remote Snap Switch Right with electrical operation from control panels. The 30-Degree Snap Crossing provides crossing capability with integrated electrical switching.

Switch Machines and Control

Separate switch machines allow retrofitting manual turnouts for remote operation or replacing failed mechanisms. The Manual Switch Machine - Left and Manual Switch Machine - Right provide manual control, while Remote Left-Hand Switch Machine and Remote Right-Hand Switch Machine enable electrical operation from control panels or DCC systems.

Crossings: Track Intersections

Atlas offers crossings at multiple angles enabling complex track arrangements and junction construction. Options include 12 1/2° Crossing, 19° Crossing, 25° Crossing, 30° Crossing, 45° Crossing, 60° Crossing, and 90° Crossing covering virtually any intersection angle needed for realistic track arrangements.

Bridges: Scenic and Functional

Atlas bridge kits add vertical interest and operational realism to layouts. The Deck Bridge Kit and Warren Bridge Kit provide truss bridge options. Through truss bridges include Through Truss Bridge - Black and Through Truss Bridge - Silver. Plate girder bridges come in multiple railroad-specific paint schemes including Plate Girder Bridge, Plate Girder Bridge D&H, Plate Girder Bridge Lackawanna, Plate Girder Bridge New Haven, Plate Girder Bridge Nickel Plate Road, Plate Girder Bridge SP, and Plate Girder Bridge UP.

Track Accessories and Essentials

Essential accessories include Plastic Rail Joiners 6pks for connecting track sections, Code-100/83 Universal Rail Joiners (Nickel Silver) for mixed Code 100/83 layouts, Terminal Joiners 12pks for power connections, Straight Terminal Track, 18" Radius Terminal Section, Rerailer 1pc, Rerailers (3), and Bumpers (2). The Snap-Track Starter Set and Track Assortment provide convenient starter packages.
