The NZR WA class locomotives were a class of tank locomotive built by New Zealand Railways (NZR). Eleven were built at NZR's own Addington Workshops in Christchurch and Hillside Workshops in Dunedin. Four more were converted from old J class 2-6-0 locomotives.
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 among the last in use.
Only one WA class has been preserved, number 165. The locomotive was restored by Gisborne City Vintage Railway in 2000.[1]
