Webb developed the Alfred the Great class as an enlarged development of the Jubilee class. Like these, it had a four-cylinder compound engine. A redesign of the valve gear made them the Benbow class. After the Jubilees had been converted into two-cylinder simples, the same thing happened to 25 of the 40 Benbows from 1913 onwards. These, like the rebuilt Jubilees, came to the Renown class. 39 locomotives came to the LMS, the rest were retired by 1923.
