Co-Co is a code for a locomotive wheel arrangement with two six-wheeled bogies with all axles powered, with a separate motor per axle. Co+Co is the code for a similar wheel arrangement but with an articulated connection between the bogies. The equivalent UIC classification for this arrangement is CoCo.
