Service history edit

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]
