The sole member of the class was built by Beyer, Peacock and Company in 1910, and entered service the following year, as no. 31 in the DHR fleet.[1] Its basic dimensions were designed to be roughly equivalent to those of two of the DHR's existing B Class 0-4-0ST engines, with the intention that it would produce approximately double the power of those engines. However, in practice it was only able to haul 65% more load than a single B Class unit.[3]
Although the DHR did not acquire any further articulated locomotives, no. 31 remained in service until November 1954.[3]
