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.

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