Remarks:     These small tank engines were the Manawatu Railway's first "main-line" locomotives. They were useful engines and after assisting with construction work, were assigned to Wellington and Paekakariki with a spare engine at Longburn. For the next two years, until the arrival of the first Baldwin "Consolidations", they worked all traffic and on the heaviest turns of duty as many as three would be required to lift a single train over the steep grades. Eventually they were superceded by more powerful locomotives and relegated to shunting and banking duties, and to the haulage of ballast trains. By the turn of the century, two had been sold off and when the Government took over the company, the remaining three were inducted into the NZR system and given the class 'Wh'.
