| Remarks: These small locomotives proved that they were fond of hard work and were a substitute for the overweight Naysmith, Wilson 'P's. For several years they were used on goods train in the South Island, but between 1898 and 1902, they were transferred to the North Island for service on the Wairarapa and Napier lines. These engines had a rather exposed footplate, the boiler backhead was level with the back of the cab, so the fireman had to stand on the tender to fire. |
