Steam locomotive
Most British express-passenger locomotives built between 1930 and 1950 were 4-6-0 or 4-6-2 types with three or four cylinders (e.g. GWR 6000 Class, LMS Coronation Class, SR Merchant Navy Class, LNER Gresley Class A3). From 1951, all but one of the 999 new British Rail standard class steam locomotives across all types used 2-cylinder configurations for easier maintenance.
