The NZR Q class were a pair of 2-4-4T type tank engines built by Rogers Locomotive and Machine Works in New Jersey. They were similar, in appearance, to the earlier K class of the same manufacturer and were purchased by the Rakaia & Ashburton Forks Railway Company [1] for working their newly constructed railway to Methven from Rakaia, which later became the Methven Branch.

The NZR A class of 1873 consisted of three types of steam locomotives used on New Zealand's railway network of similar specification but differing detail. The first and most numerous were from the Dübs and Company, the next from the Wellington firm E.W. Mills Lion Foundry, and the last from the Scottish firm of Shanks. The specifications are for the Dubs Yorkshire engines.

The Methven Branch was a branch line railway that was part of New Zealand's national rail network in Canterbury. It opened in 1880 and operated until 1976.

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 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>A</sup> class

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".

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 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 simply 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.

NZR L<sup>A</sup> class

The NZR LA class was a class of 4-4-0T steam locomotives used by the New Zealand Railways Department and the New Zealand Midland Railway Company. They were built by Nasmyth, Wilson and Company in 1887 for New Zealand Midland Railway Company, and were taken over by NZR in 1900, when the government acquired the incomplete Midland line. The designation also applies to the NZR 4-4-0Trebuilds of the Avonside L class of 1875 which were later reclassified LB after being rebuilt as 4-4-2Ts.

The Canterbury Provincial Railways was an early part of the railways of New Zealand. Built by the Canterbury Provincial government mainly to the broad gauge of 5 ft 3 in, the railway reached most of the Canterbury region by the time the province was abolished in 1876. Edward Dobson, the Provincial Engineer from 1854 to 1868, was the designer and overseer.

<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.

<span class="mw-page-title-main">Rakaia railway accident</span>

The Rakaia railway accident at Rakaia, Canterbury, New Zealand on the evening of Saturday, 11 March 1899 occurred when the second of two excursion trains returning from Ashburton to Christchurch ran into the rear of the first at the Rakaia Railway Station, killing four passengers. While due to excessive speed, the accident resulted in overdue improvements by New Zealand Railways to signalling and braking.

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.

The NZR WA class locomotives were a class of Tank locomotive built for use for New Zealand Railways (NZR). 11 were built in-house at the Addington Workshops and at Hillside Workshops. 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."

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

The NZR Y class was a class of three 0-6-0T tank steam locomotives. Built by the Hunslet Engine Company for the Public Works Department in 1923, all three were sold to NZR between 1938 and 1945.
