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 WD class was a class of tank locomotive built by Baldwin Locomotive Works to operate on New Zealand's national rail network.

<span class="mw-page-title-main">NZR O class</span> Class of steam locomotives in New Zealand

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 After almost four decades of service, all six were withdrawn in May 1922.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.

NZR A<sup>A</sup> class

The NZR AA class consisted of ten steam locomotives built by Baldwin Locomotive Works in 1914 to an order by Chief Mechanical Engineer, H. H. Jackson for operation on New Zealand's national rail network.

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.

NZR N<sup>C</sup> class

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.

NZR O<sup>B</sup> class

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.

NZR O<sup>C</sup> class

The OC class, built by the Baldwin Locomotive Works for the Wellington and Manawatu Railway (WMR) in New Zealand, consists of a solitary steam locomotive. Ordered in 1896 as an externally similar but more powerful version of the OA class locomotive ordered in 1894, it entered service in June 1897 as No. 16. It was a Vauclain compound locomotive.

<span class="mw-page-title-main">NZR E class (1906)</span>

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

<span class="mw-page-title-main">NZR P class (1876)</span>

The NZR P class was a class of two 0-6-0ST locomotives built to work on the government-owned national rail network of New Zealand in 1876. They were initially ordered by the Otago Provincial Council, but they were soon incorporated into the national locomotive fleet when the provinces were abolished. Other examples of the P class were built for industrial service and never came under the ownership of the New Zealand Railways Department, though one worked on the Kaitangata Line.

NZR B<sup>C</sup> class

The 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.

<span class="mw-page-title-main">NZR H class</span>

The NZR H class steam locomotive was 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.

<span class="mw-page-title-main">NZR W class</span>

The NZR W class consisted of two steam locomotives built at the Addington Railway Workshops in Christchurch, New Zealand by the New Zealand Railways Department (NZR). They were the first locomotives to be built by NZR.

NZR U<sup>D</sup> class

The NZR UD class was a class of two 4-6-0 steam locomotives built by the Baldwin Locomotive Works in 1904 for the Wellington and Manawatu Railway Company. When that company was nationalised in 1908, they passed into the ownership of the New Zealand Railways and received the designation UD.

NZR W<sup>J</sup> class

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.

NZR W<sup>A</sup> class

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.

<span class="mw-page-title-main">NZR L class</span>

The NZR L class were a series of ten small tank engines built in England for the New Zealand Railways Department (NZR) during the early years of the development of New Zealand's railway network.

<span class="mw-page-title-main">NZR M class</span>

The NZR M class were a series of four tank engines built in England for the Otago railways Bluff to Winton section. They were acquired by NZR in the late 1870s and rebuilt in the late 1880s. As rebuilt they were not very successful and were used in shunting duties until retirement in the 1920s.

NZR U<sup>B</sup> class

The NZR UB class were a series of Ten Wheelers built by American manufacturers for New Zealand Railways (NZR) around the start of the twentieth century. Two batches were built by Baldwin in 1898 and 1901. The earlier engines had slide valves and inside Stephenson motion, the later had piston valves and Walschaerts valve gear, as well as a higher boiler pressure.

NZR W<sup>G</sup> class

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 W<sup>W</sup> class Class of 50 (+14) New Zealand 4-6-4T locomotives

The NZR WW class was a class of 4-6-4T tank locomotives that operated on the New Zealand national railway network. They were built for New Zealand Railways Department (NZR), and were the final development of the six-coupled tank engine in New Zealand, the penultimate class of tank locomotives to be built for NZR, and the first class of tank locomotives to be built with superheaters.
