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.

Introduction

The WMR ordered No.17 from the Baldwin Locomotive Works. It entered service on 10 June 1902 and was at the time the most powerful locomotive to operate in the country. No.17 was the only 2-8-2 "Mikado" to run in New Zealand. It was a Vauclain compound, and its trailing truck bore similarities to the Q class, the world's first 4-6-2 "Pacific" type then under construction by Baldwin for NZR. [3]

The locomotive was designed to haul trains on the WMR's steep main line between Wellington and Paekakariki, and it proved capable of hauling a 280-ton freight train up the steep grades. This line became the southern portion of the North Island Main Trunk Railway when acquired by NZR in 1908.

Withdrawal

No.17/BC 463 worked this line its entire life. It operated for nearly two decades in NZR's ownership until it was withdrawn on 31 March 1927 along with fellow surviving WMR locomotives when NZR adopted a rapid locomotive standardisation plan in the 1920s. [3] It did not survive to be preserved. A decade after it was withdrawn, the steepest section of its former line was bypassed by the Tawa Flat deviation and became the Johnsonville Branch.

Railway preservation in New Zealand

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.

NZR T class

The NZR T class was a class of steam locomotive used in New Zealand; of the "Consolidation" type, popular in North America, especially with the narrow gauge Denver and Rio Grande Western Railroad.

NZR N class

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.

Wellington and Manawatu Railway Trust

The Wellington and Manawatu Railway Trust is a charitable trust based in Wellington, New Zealand, and is actively restoring former Wellington and Manawatu Railway locomotive No.9, to full working order.

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>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.

NZR E class (1906)

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

NZR P class (1876)

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 class (1899)

The NZR B class of 1899 was a class of steam locomotives that operated on New Zealand's national rail network. An earlier B class of Double Fairlies had entered service in 1874, but as they had departed from the ownership of the New Zealand Railways (NZR) by the end of 1896, the B classification was free to be re-used. Despite early difficulties, they were amongst NZR's most influential designs.

NZR B<sup>B</sup> class

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).

NZR R class

The NZR R class was a class of early 0-6-4T single Fairlie steam locomotives operated by New Zealand's Railways Department (NZR) between 1879 and 1936.

NZR V class

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.

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.

Wellington and Manawatu Railway Company

The Wellington and Manawatu Railway Company was a private railway company that built, owned and operated the Wellington-Manawatu railway line between Thorndon in Wellington, the capital of New Zealand, and Longburn, near Palmerston North in the Manawatu, between 1881 and 1908, when it was acquired by the New Zealand Government Railways. Its successful operation in private ownership was unusual for early railways in New Zealand.

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>H</sup> class

The NZR WH class was a class of three steam locomotives built by Manning Wardle in 1884 for service on New Zealand's private Wellington and Manawatu Railway Company (WMR). They did not acquire their WH classification until 1908 when WMR was nationalised and incorporated into the New Zealand Government Railways (NZR). A total of five locomotives were purchased by the WMR but two had been sold by the time NZR took over the company.

NZR U class

The NZR U class, the first tender locomotives built in New Zealand, were a class of 4-6-0 Ten Wheeler locomotive designed to the requirements of Mr T. F. Rotherham and built at NZR Addington between 1894 and 1903. They were amongst NZRs' longest lived tender engines.
