| Remarks: A tank version of the famous 'Ab', these massive, capable-looking locomotives were originally designated 'Ws'. Both Classes were identical in principle dimensions, the chief differences being the positioning of the sand domes and the distribution of weight. The 'Ws' was intended for suburban haulage and the 'Wab' for short-distance main-line work. this distinction continued until 1932-35, when the 'Ws' locomotives were redesignated 'Wab'. It was in suburban passenger service at Auckland and Wellington that the 'Wab'; made its mark. Fourteen classed W's until 1930s. Eleven rebuilt to Ab class 1947-1957. The design was intended for use on the North Island Main Trunk between Taihape and Taumarunui, but ended up in various places throughout the country and excelled in suburban passenger work, when they were fitted with an American "Delta" trailing truck for bunker first running. A large number of 'Ab' drawings was used in its design. |
