Kadee® Quality Products was formed with the goal of providing a realistic and reliable automatic coupler. Since 1946 Kadee® has remained a leader within the model train hobby. Our earliest version of a knuckle coupler, the “K” series prototype, was the first model train coupler to combine a realistic looking design with a fully-functioning mechanism that operated just like the real ones. Today we employ American workers and support American families while we continue to design, manufacture, print, and produce our products in White City, Oregon, USA.
