These locomotives were built as shunting engines to use ‘parts on hand’. The cylinders had been ordered for a project that did not eventuate and the wheel sets came from B15 engines.

Like the first C16s built at Ipswich , the engines had a combined number and builder’s plate mounted on the sides of the cab.

All were constructed as 6D13½ Class tank engines and were converted to tender engines between 1932 and 1938 using tenders from condemned B13 and C15 engines, to increase their water and coal capacity and possibly also to reduce their original 10.2 ton axle load. To solve weight distribution problems after removal of their side tanks, the Baldwin type sand box was placed behind rather than in the usual position of in front the steam dome.

N°400 was used as ‘ash shunter’ at Mayne and was the last of the class to be written off in 1961.

N°398 was written off the books in 1953 but was retained as Ipswich Workshops shunter until 1972 when it was replaced by DL3. The original funnel was replaced by a simple stove pipe chimney in 1960. It ran on main line excursions in 1967 and 1968 and is now preserved at Ipswich Workshops. The engines were never fitted with electric headlights.

* Originally fitted with a steam brake only then fitted with WH brake and 8 X 6½” pumps from 1914 .

These were replaced by larger 8 X 7½” pumps in 1938.
