Lionel 6-12033 | FasTrack O36 Curved Track 4-Pack - 45° Sections | O Gauge

Lionel FasTrack O36 Curved Track 4-Pack — four 45° curved sections in O Gauge, with a wide 36" diameter curve that gives semi-scale and modern Lionel locomotives plenty of room to track smoothly. The molded gray roadbed and pre-attached ties give your layout an instant ballasted look without any extra scenery work, and the snap-together pin connections lock tight so trains roll over the joints without shorts or derailments.

Eight pieces make a full O36 circle, so this 4-pack gets you a clean half-circle right out of the box — perfect for expanding an existing FasTrack oval or building out the curves on a new layout. Browse our full O Scale Track & Accessories and O Scale Trains & Track to round out your FasTrack system.

• Four 45° curved sections of O36 FasTrack — eight sections form a complete circle.
• Realistic gray molded roadbed with pre-attached ties for a finished, ballasted look.
• Snap-together pin connections lock securely and align the rails automatically.
• 36" diameter curve gives smoother running for larger O Gauge locomotives and rolling stock.
• Compatible with the full Lionel FasTrack system — switches, crossovers, straights, and accessory tracks.
• Scale: O Scale (1:48) — three-rail O Gauge.

How many of these do I need to make a full circle?
You'll need 8 sections (two of these 4-packs) to form a complete O36 circle.

Does this work with older Lionel tubular track?
No. FasTrack uses its own roadbed and pin system — you'll need a FasTrack-to-tubular transition piece to combine the two.

What's the minimum locomotive that can run on O36?
O36 is the smallest curve recommended for most modern Lionel locomotives. Most semi-scale and traditional engines run great; some larger scale-detailed locos require O54 or larger.

Are these compatible with MTH RealTrax or Atlas O?
No. FasTrack is a Lionel-only system. It does not interchange with MTH RealTrax, ScaleTrax, or Atlas O without adapter pieces.
