The locomotives were turned out in British Railways Brunswick green livery with orange and black lining with the British Railways crest on the tender side, after their first under new ownership. This was unlike the Merchant Navy class, which was initially turned out in British Railways experimental express passenger blue livery. By this stage, the Southern Railway-built locomotives were re-liveried and renumbered from 34001–34070. The rebuilt locomotives were also in British Railways Brunswick green with orange and black lining, and crest on the tender side, whilst the nameplates were placed on a custom-made mounting on the running plate due to the absence of a flat surface.
