NZR G Class (1928)
The NZR G class was a type of Garratt locomotives used in New Zealand, later rebuilt as Pacific (locomotive), Pacific type locomotives. They were the only Garratt type steam locomotives ever used by the New Zealand Railways Department, New Zealand Railways (NZR). They were ordered to deal with traffic growth over the Grade (slope), heavy gradients of the North Island Main Trunk (NIMT) and to do away with the use of banking engines on steep grades. They were one of the few Garratt designs to employ six cylinders. A mechanical stoker was used to feed coal into the locomotive. The locomotives lasted longer in rebuilt form as standard Pacific locomotives than they did as Garratts, but their numerous mechanical issues lead to their final withdrawal following a union ban on their use in 1956. Introduction About 1913, the General Manager E. H. Hiley considered the importing of ten articulated Garratt engines and ten Pacifics. With the success of the NZR AB class, AB class and NZR WAB c ...

Beyer, Peacock & Company
Beyer, Peacock and Company was an English general engineering company and railway locomotive manufacturer with a factory in Openshaw, Manchester. Charles Beyer, Richard Peacock and Henry Robertson founded the company in 1854. The company closed its railway operations in the early 1960s. It retained its stock market listing until 1976, when it was bought and absorbed by National Chemical Industries of Saudi Arabia. Founders German-born Charles Beyer had undertaken engineering training related to cotton milling in Dresden before moving to England in 1831 aged 21. He became draughtsman at Sharp, Stewart and Company, Sharp, Roberts and Company's Atlas works in central Manchester, which manufactured cotton mill machinery and had just started building locomotives for the Liverpool and Manchester Railway. There he was mentored by head engineer and prolific inventor of cotton mill machinery Richard Roberts (engineer), Richard Roberts. By the time he resigned 22 years later he was well ...

Tunnel
A tunnel is an underground or undersea passageway. It is dug through surrounding soil, earth or rock, or laid under water, and is usually completely enclosed except for the two portals common at each end, though there may be access and ventilation openings at various points along the length. A pipeline differs significantly from a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment.Salazar, Waneta.

NZR J Class (1939)
The NZR J class was a class of forty 4-8-2 steam locomotives operated by the New Zealand Railways Department (NZR). Although designed to work on the lighter secondary lines, the class was frequently used on mainline express passenger trains as well as freight. When first introduced, the class boasted distinctive streamlining, which was later removed from 1947 onwards for maintenance reasons. Three of this class remained in service until the end of steam operation on 26 October 1971, when they were withdrawn and entered into preservation. This class should not be confused with the earlier J class from 1874. Introduction The J class was primarily designed to be a mixed traffic locomotive that was more powerful than the AB class, being capable of running on the lighter secondary lines while also being able to operate express passenger trains on main routes, which were at the time operated by the larger K class locomotives and the in-production KA and KB classes. The order, i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NZR KB Class
The NZR KB class of 1939 was a class of six mixed traffic steam locomotives built for New Zealand Railways Department (NZR), that operated on New Zealand's railway network. After the success of the K class, the KB class were built to meet the increasing traffic demands on the Midland Line in the South Island. The locomotives had a wheel arrangement of 4-8-4 and first appeared with distinctive streamlining, mainly to hide their ACFI feedwater systems. History Following the success of the K class in the North Island, there was a need for similar locomotives to operate the Midland Line, primarily between Springfield and Arthur's Pass. These new locomotives incorporated a number of improvements upon the K class, including a re-designed plate frame to eliminate cracking issues the K class experienced; roller bearings on all wheels; hydrostatic lubrication throughout; and the inclusion of the ACFI feed-water system that had been pioneered on K 919. The ACFI equipment's aes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Arthur's Pass
Arthur's Pass, previously called Camping Flat then Bealey Flats, and for some time officially Arthurs Pass, is a township in the Southern Alps of the South Island of New Zealand, located in the Selwyn district. It is a popular base for exploring Arthur's Pass National Park. Arthur's Pass township is about south of the mountain pass with the same name. At an elevation of above sea level, the settlement is surrounded by beech forest. The Bealey River runs through the township. The town is located from Christchurch, a two-hour drive on State Highway 73. Naming and history The township and the pass take their names after Arthur Dudley Dobson (1841–1934, Sir Arthur from 1931). The Chief Surveyor of Canterbury Province, Thomas Cass, had tasked Arthur Dobson to find out if there was an available pass out of the Waimakariri watershed into valleys running to the West Coast. In 1864, Arthur's brother Edward Henry Dobson joined him and accompanied him over the watershed into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Midland Line, New Zealand
The Midland line is a 212 km section of railway between Rolleston, New Zealand, Rolleston and Greymouth in the South Island of New Zealand. The line features five major bridges, five viaducts and 17 tunnels, the longest of which is the Otira Tunnel, Otira tunnel. It is the route of the popular TranzAlpine passenger train. History Railway development in the South Island in the 1870s was concentrated on a main line linking the established centres of Christchurch, Timaru, Dunedin and Invercargill and light, easily constructed branch lines serving the arable plains; (see Rail transport in New Zealand#Vogel Era, Vogel Era). These later included a branch to Springfield which was reached by January 1880. In 1882 the East and West Coast Railway League was formed and in 1884 a Royal Commission, although fully aware of the construction difficulties of the Waimakariri Valley-Arthurs Pass route, as compared with the somewhat easier but longer Hurunui Valley-Harpers Pass route, ...

Tender (rail)
A tender is a special rail vehicle hauled by a steam locomotive containing its fuel (wood, coal, oil or torrefied biomass) and water. Steam locomotives consume large quantities of water compared to the quantity of fuel, so their tenders are necessary to keep them running over long distances. A locomotive that pulls a tender is called a tender locomotive. Locomotives that do not have tenders and carry all their fuel and water on board are called '' tank locomotives'' or ''tank engines''. A corridor tender is a locomotive tender with a passageway to one side, allowing crew changes on the fly. A brake tender is a tender that is heavy and used (primarily) to provide greater braking efficiency. General functions The largest steam locomotives are semi-permanently coupled by a drawbar to a tender that carries the water and fuel. The fuel source used depends on what is economically available locally. In the UK and parts of Europe, a plentiful supply of coal made this the obvious ...

Dunedin
Dunedin ( ; ) is the second-most populous city in the South Island of New Zealand (after Christchurch), and the principal city of the Otago region. Its name comes from ("fort of Edin"), the Scottish Gaelic name for Edinburgh, the capital of Scotland. The city has a rich Māori people, Māori, Scottish people, Scottish, and Chinese people, Chinese heritage. With an estimated population of as of , Dunedin is New Zealand's seventh-most populous metropolitan and urban area. For cultural, geographical, and historical reasons, the city has long been considered one of New Zealand's four main centres. The urban area of Dunedin lies on the central-eastern coast of Otago, surrounding the head of Otago Harbour. The harbour and hills around Dunedin are the remnants of an extinct volcano. The city suburbs extend out into the surrounding valleys and hills, onto the isthmus of the Otago Peninsula, and along the shores of the Otago Harbour and the Pacific Ocean.

Hutt Workshops
The Hutt Railway Workshops is a major railway engineering facility in the Lower Hutt suburb of Gracefield in the Wellington region of New Zealand's North Island. It is state-owned enterprise KiwiRail's only workshops, and was opened in 1930. This facility is the central motive power maintenance operation and also maintains rolling stock. History Predecessor The Hutt Workshops were preceded by a workshops at Petone, adjacent to the railway station. It operated from 1876 when first used to store the H-class "Fell" locomotives until its replacement in 1929. Decision to move In the 1920s, the problems caused by the inadequacy of some railway workshop facilities was becoming more acute. In order to examine the issue, a Royal Commission was established in 1924 consisting of English railwaymen Sir Sam Fay and Sir Vincent Raven. One recommendation of their report read: "In the North Island the shops at Napier, Whangārei, and East Town, so far as locomotive work is concerne ...

NZR K Class (1932)
The NZR K class of 1932 was a class of mixed traffic 4-8-4 steam locomotives built by the New Zealand Railways Department (NZR) that operated on New Zealand's railway network. The locomotives were developed following the failure of the G class Garratt locomotives. The class should not be confused with the much earlier K class of 1877-78, the first American-built engines to arrive in New Zealand. History The three G class locomotives were introduced by NZR in response to increased tonnages, especially on the mountainous, demanding North Island Main Trunk Railway. However, various faults led to their swift withdrawal from service and NZR still needed a large and powerful type of locomotive. It decided to develop a conventional rather than articulated locomotive, to avoid a repeat of the G class failure. Initially conceived as a 4-8-2 locomotive, the K class was to be at least 50% more powerful than the AB class, and due to New Zealand's narrow gauge track and limited loading g ...
