These twelve six and a half foot singles were designed by Beattie for the LSWR and built from 1856 onwards. After the name of the first machine, the locomotives were referred to as the “Canute class”. Many parts made of polished brass and the highly ornamental wheel arches were visually striking. Technically noteworthy was the firebox with combustion chamber. The service life of the locomotives ended between 1875 and 1885.
