Talk:NZR AB class
From Wikipedia, the free encyclopedia
Eight Wab tank locos were converted to Ab in the early 1950s, following the electrification of the Hutt Valley suburban services - this made the Wellington-based Wab class redundant but there was still increasing need for medium-sized tender locomotives. This brought the class total for Ab to 149. A further two North British-built examples were lost in the wreck of the 'Wiltshire' in 1922.
