The NZR WA class locomotives were a class of Tank locomotive built for use for New Zealand Railways Department. 11 were built inhouse at Addington Workshops and at Hillside Workshops. Four more were converted from old J class 2-6-0 locomotives.[1][2] Three were fitted with brakes to assist descent on the Fell-operated Rewanui and Roa inclines on the South Island's West Coast Region. These were amongst the last in use.
