The NZR WB class was a class of tank locomotives that operated in New Zealand. Built in 1898 by the Baldwin Locomotive Works, the twelve members of the class entered service during the first five months of 1899. Eight were withdrawn by the end of 1935, while four others survived with new boilers until the mid-1950s.
