No. 735 with round-topped firebox
Locomotive Magazine, July 1901

The class D express locomotives were among Wainwright's first designs for the SE&CR. They were colorfully decorated to attract more public attention. They were built by different manufacturers, from 1905 also with Belpaire fireboxes. From 1921 Maunsell rebuilt some into the heavier class D1, which had a Belpaire firebox, a superheater, piston valves and a new cab. Eleven more were rebuilt between 1923 and 1926. A larger number of withdrawals took place from 1951 and the last rebuilt class D1 locomotives disappeared in 1961. So far there is only a short text for this vehicle. In the future it will be described in more detail.
