Railway preservation in New Zealand is the preservation of historically significant facets of New Zealand's rail transport history. The earliest recorded preservation attempt took place in 1925, although the movement itself did not start properly until 1960.
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 Eight were withdrawn by the end of 1935, while four others survived with new boilers until the mid-1950s.
The NZR WD class was a class of tank locomotive built by Baldwin Locomotive Works to operate on New Zealand's national rail network.
The NZR O class consisted of six steam locomotives that operated on New Zealand's national rail network. Ordered from the Baldwin Locomotive Works of Pennsylvania in 1885, three arrived in time to begin work in December 1885, while two more were placed in service in January 1886 and the sixth in February 1886. After almost four decades of service, all six were withdrawn in May 1922. None survived to be preserved, although two engine frames and 5 tenders from O class locomotives are known to exist near Summit on the former Rimutaka Incline.
The N class were 12 steam locomotives that operated on the national rail network of New Zealand. They were built in three batches, including one batch of two engines for the private Wellington and Manawatu Railway Company, the WMR, by the Baldwin Locomotive Works in 1885, 1891, and 1901. Previously the N class designation had been applied between 1877 and 1879 to Lady Mordaunt, a member of the B class of 1874.
The NZR NA class was a class of two steam locomotives that operated on the privately owned Wellington and Manawatu Railway (WMR) and then the publicly owned New Zealand Railways (NZR). Ordered by the WMR to operate on its line up the west coast of the North Island north of Wellington, the first was built in 1894 by the Baldwin Locomotive Works and entered service that year as WMR No. 14. In 1896, a second locomotive that was slightly more powerful was ordered from Baldwin, and it entered service in October 1897. The engines were similar to the two members of the N class ordered in 1891, except they were heavier and more powerful. They were Vauclain compound locomotives.
The NZR NC class was a class of two steam locomotives built by Baldwin Locomotive Works built for service on New Zealand's private Wellington and Manawatu Railway (WMR). They did not acquire their NC classification until the publicly owned New Zealand Railways Department (NZR) purchased the WMR and its locomotive fleet.
The OB class was the first class of steam locomotives constructed by the Baldwin Locomotive Works for the Wellington and Manawatu Railway Company (WMR) in New Zealand. The class consisted of two locomotives ordered in 1888, and they entered service in September of that year as WMR No.'s 11 and 12.
The OA class is a solitary steam locomotive built by the Baldwin Locomotive Works for the Wellington and Manawatu Railway (WMR) in New Zealand. Ordered in 1894, it entered service in August of that year as No. 13 and was the first narrow gauge Vauclain compound in the world. In 1908, the WMR and its locomotive fleet were purchased by New Zealand Railways Department (NZR) and incorporated into the national rail network, and, although No. 13 bore a likeness to members of the O class, it was sufficiently different that it warranted separate classification. The designation of OA was created and it was numbered OA 457. It operated for another two decades until it was withdrawn in December 1929 in Auckland. The locomotive was known to WMR staff as "The Lady".
The New Zealand E class locomotive comprised a single Mallet steam locomotive operated by New Zealand Railways (NZR) from 1906 until 1917. Classified as E 66 and nicknamed Pearson's Dream after its designer, it was an experimental Mallet locomotive designed to work on the Rimutaka Incline. The "E" classification was previously used by the Double Fairlie E class of 1872-75, but the classification was free as they had all been withdrawn by the time E 66 entered service. After the withdrawal of E 66, "E" was again re-used on the battery-electric E class of 1922. It was the only Mallet locomotive to operate for the NZR
The NZR BB class of steam locomotives comprised 30 engines operated by the New Zealand Railways (NZR) in the North Island of New Zealand. Ordered to replace smaller locomotives of several classes in the North Island, they were similar in design and appearance to the preceding B and BA classes. The first BB class locomotive entered service in February 1915, with the last to commence operations doing so on 8 March 1917. All were built by A & G Price Ltd of Thames, New Zealand, and as their cylinders had a larger diameter than the B and BA locomotives they were capable of generating more power to haul heavier trains. The most visible difference however was the roundtop firebox in place of the preceding classes Belpaire design. The BB class could haul up to 700 long tons of freight on a level railway line, though they were limited to a top speed of around 40 mph (64 km/h).
The NZR BC class comprised a single steam locomotive that operated on New Zealand's national rail network. Built for the Wellington and Manawatu Railway (WMR) and classified as No. 17, it passed into the ownership of the New Zealand Railways Department (NZR) when the government purchased the WMR in December 1908, and it was then that it acquired the BC classification as BC 463.
The NZR H class steam locomotive is a unique class of Fell locomotive used by New Zealand Railways (NZR) on the Rimutaka Incline, the 3-mile (4.8 km) section of 1 in 15 gradient between Cross Creek and Summit, over the Rimutaka Ranges.
The NZR Q class was an important steam locomotive class not only in the history of New Zealand's railway network but also in worldwide railways in general. Designed by New Zealand Government Railways' (NZR) Chief Mechanical Engineer A. L. Beattie and ordered from the Baldwin Locomotive Works in 1901, they were the first locomotives in the world to be built with the wheel arrangement of 4-6-2. This wheel arrangement came to be known as the Pacific type after the voyage the completed locomotives made across the Pacific Ocean to New Zealand. A few instances of the 4-6-2 wheel arrangement are known to have existed prior to 1901, but these were all reconstructions of locomotives that were originally built with a different wheel arrangement, thereby making the thirteen members of the Q class the first "true" Pacifics in the world. The Pacific style went on to become arguably the most famous wheel arrangement in the world.
The New Zealand V class steam locomotive was used on New Zealand's railway network from 1885 onwards. They were operated by New Zealand Government Railways and the Wellington and Manawatu Railway Company.
The NZR WJ class was a class of one steam locomotive built by Baldwin Locomotive Works for service on New Zealand's private Wellington and Manawatu Railway (WMR). She acquired the WJ classification when the publicly owned New Zealand Railways Department (NZR) purchased the WMR and its locomotive fleet in 1908.
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.
The NZR WE Class were rebuilt from earlier Sharp Stewart built B class locomotives. In service, the first two were tried on the Rimutaka Incline, however, they lacked the required adhesion on the 1 in 15 (6.67%) grade. They were later transferred to Greymouth for use on the Rewanui Incline, where they were far more successful, on the line's 1 in 25 (4%) grade. It is not known if they ever operated on the Roa Incline.
The NZR WG class was a development of the preceding WF class of all purpose tank locomotive. Later in their careers most (14) were rebuilt as WW class. The locomotives were designed by A. L. Beattie, who described them as a "large tank locomotive."
NZR H199 Mount Cenis is a preserved NZR H class 0-4-2T steam locomotive. It is the only surviving rack locomotive in New Zealand and the only surviving steam locomotive to use the fell rack system in the world. The locomotive is preserved at the Fell Engine Museum in Featherston.
