An order was placed in February 1882, with the Vulcan Foundry for six 2-4-0T locomotives to the specification of the then Acting Locomotive Engineer, Mr Scott. During Mr Scott’s subsequent absence in England on official business, Thomas Middleton, Locomotive Engineer, had the specifications altered to 0-6-0T wheel arrangement, together with other variations to the original order. Middleton claimed that the revised design would enable the locomotives to run at in suburban service. Commissioner Goodchap approved the changes and despite the protests on Scott’s return, the variations were made.
