The Class D express locomotives were among Wainwright's first designs for the SE&CR. They were brightly colored to attract more public attention. They were built by different manufacturers, from 1905 also with Belpaire fireboxes. From 1913 Maunsell rebuilt some machines into the heavier class D1, which also had a Belpaire firebox. From around 1920, most of them received a superheater. A larger number of withdrawals took place from 1951 and the last rebuilt class D1 locomotives disappeared in 1961.
