Our N-Possible couplers are scale-sized N scale couplers. That means no more "boxing gloves" overpowering your finely detailed models. Good looks mean nothing if the couplers don't do their job of reliably coupling cars. Our N-Possible couplers out-perform other knuckle style couplers by every metric.


N-Possible coupler features realized by the Patent Pending N-Possible spring mechanism:

Precise Scale Design: Enhance authenticity with a meticulously detailed prototypical appearance. Compatible with other scale designs but not conventional couplers.

Ultra-Low Force Automatic Coupling: Experience reliable scale-speed switching with minimal coupling force and easy pick uncoupling.

Easy Installation: The retained spring design simplifies installation into car integrated boxes.

Slip-Resistant Performance: Stays connected on uneven trackwork, maintaining reliability.

Reliable Alignment: Dependable reverse movements and DPU/helper operation.

Versatile Shank Lengths: Three shank lengths for prototypically accurate coupler configurations.

Various Versions Available: Choose spring-mounted versions or kits.

​No Slinky Effect: Eliminates the “slinky” effect for a realistic look


The N-Possible is available in two formats and multiple lengths. The URS series is for installation in existing coupler boxes while the SBX series includes replacement coupler boxes for more custom installation needs.


NOTE: Due to their perfect scale design, N-Possible scale couplers are too small to properly mate with traditional N-Scale couplers from any manufacturer, which are all significantly oversize. One can readily accommodate a mixed fleet by using conversions cars (a car with a traditional coupler on one end with a N-Possible scale coupler on the other). MTL True-Scale couplers are fully compatible with N-Possible couplers due to their scale design.
