The class was given the Power Classification of 0P, and initially carried the Southern livery with the addition of 'British Railways' on the water tank sides, though this was promptly changed to the BR Standard Mixed-Traffic Black livery with red and white lining.

The Isle of Wight's unique numbering system was retained on the BR examples on the island, along with the names.

The mainland complement were renumbered by the addition of 30000 to their existing Southern Railway numbers to give a new number in the 30177 to 30236 sequence.
