After months of research, model construction and testing, the Blue Ribbon Committee finalized on the Coupler Contour 20240815, shown above. This is based on the American Association of Railroads (AAR) Contour 10A, also known as the "E" Coupler.

	A full-size model of the 10A Contour was ~~built~~ in Fusion360. The model was scaled to 1/8, then used to create a closed gauge. The gauge was printed in PLA (plastic) and was tested with several couplers of different manufacturers. The scaled 10A Contour was a better match compared to the GGLS Contour with the several couplers tested.		A full-size model of the 10A Contour was constructed in Fusion360.
