However, despite Bulleid's experimentation with Malachite Green livery on express passenger locomotive, the Maunsell livery was continued with the S11s, though the 'Southern' lettering on the tender was changed to the 'Sunshine Yellow' style.
Livery after Nationalisation was initially Southern Wartime Black livery with 'British Railways' on the tender, and an 'S' prefix on the number, until superseded by the Standard BR 30xxx series.
