The O Atlas NS O-72 Left Hand Remote Switch and O Atlas NS O-72 Right Hand Remote Switch provide wide-radius turnouts for mainline speeds. The O Atlas NS O-72 WYE Remote Switch creates three-way junctions for engine terminals and industrial trackage. The O Atlas NS #5 Turnout Left and O Atlas NS #5 Turnout Right replicate prototype #5 turnouts with realistic frog angles. The O Atlas NS #7.5 High Speed Switch-Left and O Atlas NS #7.5 High Speed Switch-Right enable high-speed diverging routes through turnouts.
Create complex track arrangements with Atlas O crossings and specialty track. The O Atlas NS 22.5 Degree Crossing, O Atlas NS 45 Degree Crossing, O Atlas NS 60 Degree Crossing, and O Atlas NS 90 Degree Crossing provide various crossing angles for diamonds, junctions, and complex interlockings. The O Atlas NS #5 Double Slip Switch combines two turnouts and a crossing in one compact unit, enabling trains to cross or diverge in either direction through a single track element. These specialty track pieces replicate prototype railroad trackwork found at busy terminals, junctions, and industrial areas.
Create custom curves, easements, and irregular track alignments with Atlas O flex track. The O Atlas NS 40 inch Custom Flex Track-Wood Ties and O Atlas Custom Flex Track-Wood Ties provide bendable track that conforms to any desired radius or compound curve. Flex track enables smooth transitions between different curve radii, realistic easements entering and exiting curves, and custom track alignments that follow terrain contours or fit irregular spaces. The flexible rail can be bent to any radius within the track's physical limits, offering unlimited layout design possibilities beyond fixed-radius sectional track.
Enable remote uncoupling operations with Atlas O uncoupling track. The O Atlas NS 1 3/4 inch Uncoupling Track incorporates electromagnetic uncoupling mechanisms that activate knuckle couplers, allowing operators to spot cars precisely and perform realistic switching operations without manual intervention.

Successful O scale 3-rail layouts begin with careful track planning that considers available space, operational goals, and scenic possibilities. Minimum radius curves determine which locomotives and rolling stock can operate reliably. Turnout placement affects switching operations and operational flexibility. Crossing angles impact track spacing and junction complexity. Proper planning ensures adequate clearances, realistic track spacing, and operational efficiency. Atlas O's variety of curve radii, turnout sizes, and specialty trackwork enables creation of track plans ranging from simple continuous loops to complex point-to-point railroads with multiple industries, yards, and passing sidings.
Three-rail track systems use the center rail for positive power and the outer rails for common return, simplifying wiring compared to 2-rail systems. However, proper electrical distribution remains essential for reliable operation. Multiple power feeds prevent voltage drop on large layouts. Block wiring enables independent train control in different layout sections. Insulated track sections create electrical isolation for accessories and operating features. Terminal tracks and feeder wires ensure adequate power reaches all layout areas. Atlas O's nickel silver rail provides superior electrical conductivity compared to steel rail, maintaining clean electrical contact and reducing power distribution challenges.
Proper track installation ensures smooth operation and realistic appearance. Secure track to roadbed or layout surface using appropriate fasteners or adhesive. Maintain consistent rail height and alignment across joints. Test electrical continuity throughout track sections. Ballast track with appropriate materials scaled for O gauge, applying ballast between ties and along shoulders. Secure ballast with diluted adhesive that penetrates ballast without creating hard, unrealistic surfaces. Properly installed and ballasted Atlas O track replicates prototype railroad appearance while delivering reliable electrical and mechanical performance.
Regular track maintenance ensures continued reliable operation. Clean rail surfaces remove oxidation, dirt, and oil residue that impede electrical contact. Atlas O's nickel silver rail resists oxidation better than steel rail but still requires periodic cleaning. Use appropriate track cleaning methods including abrasive pads, track cleaning cars, or chemical cleaners. Inspect rail joints for proper alignment and electrical continuity. Check turnout points for smooth movement and proper contact. Maintain clean wheel treads on locomotives and rolling stock to prevent dirt transfer to rails. Proper maintenance extends track life and ensures consistent locomotive performance.
