| Remarks: These distinctive "Consolidation" freight locomotives were practically the same as the highly successful engines Baldwin had designed and built for America's pioneer narrow-gauge railwy, the 3'0" Denver and Rio Grande. With small coupled wheels the "T's" were normally restricted to a maximum speed of 18 m.p.h., but sometimes hauled express trains between Oamaru and Dunedin. In 1900, these locomotives were reboilered and equipped with Belpaire fireboxes raising their working pressure to 160 psig and the heating surface to 920 sq ft and treated to a steel cab. For several years, these Baldwin's were the most powerful locomotives on the NZR. |
