Editing 2-8-0 (section)

===New Zealand===
Several 2-8-0 locomotives were supplied to New Zealand by the [[Baldwin Locomotive Works]] of [[Philadelphia]] in the United States. Six [[NZR O class|O Class]] locomotives were built for the [[New Zealand Railways Department|New Zealand Railways]] in 1885.

The [[Wellington and Manawatu Railway Company]], which operated the [[Wellington - Manawatu Line|Wellington-Manawatu line]], had four similar locomotives built by Baldwin, two in 1888, one in 1894 and one in 1896. The WMR locomotives of 1894 and 1896, No. 12 and No. 13, were [[Vauclain compound]] locomotives, the first in New Zealand and the first narrow-gauge compounds in the world. While standard gauge compounds usually had the low-pressure cylinder mounted below the high-pressure cylinder on each side, this was often reversed on narrow-gauge locomotives, which had the larger low-pressure cylinders mounted above the high-pressure cylinders to provide greater clearance at platforms.

In 1908, when the WMR was nationalized, these locomotives were classified into three NZR subclasses because of detail differences, the two 1888 locomotives as [[NZR OB class|O<sup>B</sup> class]], the 1894 locomotive as [[NZR OA class|O<sup>A</sup> class]], and the 1896 locomotive as [[NZR OC class|O<sup>C</sup> class]].
