Service history

The two members of the A class, nos D19 and D20, were ordered in 1919 and completed in 118 working days. They were dismantled, boxed, and shipped on 5 April 1920, before entering service later that year.[1]

Both locomotives survived the dieselisation of the MRWA in 1958 as emergency power. They were written off in April 1963, and scrapped soon afterwards.[2]
