Data from "The Locomotive History of the London, Brighton and South Coast Railway," The Locomotive & Railway Carriage & Wagon Review, Vol IV (July 1899), p. 106.
Robert John Billinton introduced this maid-of-all-passenger-work (up to a point) wheel arrangement to the LB & SCR. Because of the popularity of the 0-4-4T layout for the repeated stop-and-start nature of commuter work, it surprised some observers that this was the only such class the LB & SCR would produce. Brighton turned out the class from 1892 to 1896.
They were a solid success, serving branch and main lines for decades. 26 survived to be taken into British Railways under the 1948 Nationalization.
