Rusty Rails OO gauge 8mm Buckeye Magnetic Couplings

Upgrade your rolling stock with the next generation of model railway connectivity - Rusty Rails Modelling Magnetic Buckeye Couplings.

These are 8mm long* Magnetic Buckeye Couplings - seven pairs of couplings per pack

Designed and hand-assembled in North Wales, UK, these premium OO gauge magnetic couplers offer model railway enthusiasts a perfect blend of realistic presentation, reliable performance and effortless coupling.

By eliminating unsightly traditional tension-lock couplers, these sleek, low-profile alternatives add an authentic layer of detail to your layout while ensuring your trains remain securely connected over gradients and through complex trackwork.

Key Features

• Handcrafted Quality: Each coupler is 3D printed and hand-assembled by Birch (Rusty Rails Modelling) in North Wales, ensuring consistent quality and attention to detail.
• Premium Materials: Made from high-grade black resin for a durable, clean finish that blends seamlessly with your models.
• Strong Magnetic Hold: Fitted with ultra-strong N52 neodymium magnets (3mm × 2mm) for a secure and reliable connection under normal operating loads.
• Universal Fit: Designed for standard NEM sockets, allowing quick and easy installation across a wide range of locomotives and rolling stock.
  
• 8mm length – closer, more prototypical spacing (best on wider curves)
  

Installation & Compatibility

Installation is simple - push the coupling shaft into a standard NEM socket until firmly seated.

• Suitable for most modern rolling stock with NEM pockets
• Not compatible with step-down connectors (e.g. Bachmann Mk1 coaches), as contact with the chassis may cause friction and reduce performance

Polarity Guidance

Correct polarity is essential for proper operation. Each coupling has a small moulded bolt indicator near the magnet.

• Align indicators consistently across your fleet so magnets attract rather than repel
• Use a standard orientation (e.g. all indicators facing the same side) for full compatibility between stock

Care & Safety

• Scale: OO Gauge (1:76)
• Material: Black photopolymer resin
• Magnet: N52 neodymium
• Recommended Age: 12+

Warning: Choking hazard – small parts. Contains strong magnets. Keep away from children under 5. Seek immediate medical attention if magnets are swallowed.
