Remarks:     These chunky little tank locomotives were placed into service in both North and South Islands. Like their predecessors of Class 'Wb', they were typically American in all respects but having a larger cab and coal bunker. They soon proved to be a most useful locomotive and were being used for almost every kind of duty from shunting to running express trains on steeply graded main lines. In passenger service they were expected to run to time with loads of 200 tons on reasonably level track. With freight service under the same conditions they would handle 400-500 tons.
