The British Railways Mark 3 coach is a type of coaching stock produced for British Railways between 1975 and 1988 which has since been operated by various railway companies. They are currently used for loco-hauled services on a small number of routes but are mostly used as carriages for the BR Class 43 HST. In Train Sim World, they are featured in Great Western Railway livery in the Great Western Express dlc. First class, second class and buffet car variants are featured at present.
