The kitchen car contained no passenger accommodation. Its sole purpose was to provide meals when the demand was greater than could be met by a kitchen/dining car. They were marshalled between at least one open first (e.g. COMET MODELS M16, M33, M34) and one or two open thirds (e.g. COMET MODELS M4, M5, M21, M22, M40, M41, M42). They were also used on excursion trains serving the open coaches which usually made up such services. Six were rebuilt by BR as “Party Cars” in 1955.
