NZR Q Class
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 had to make 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. Design The Q class's design stems from the require ...

Builder's Photo
A builder's photo, also called an official photo, is a specific type of photograph that is typically made by rail transport rolling stock manufacturers to show a vehicle that has been newly built or rebuilt. The builder's photo is meant to show an overview of the basic exterior form of a unit of rolling stock. Photographs made by railfans that show similar features to builder's photos are sometimes informally referred to as roster shots. Builder's photos were also made by some automobile manufacturers to show a representative sample of new models they produced. Prints of builder's photos were also often made for executives of the manufacturers and railroad companies to hang in their offices. Builder's photos were also reproduced as post cards as well as reprinted in advertisements to promote the railroad companies or manufacturers depicted therein. In the United Kingdom, steam locomotives were often temporarily painted in photographic grey color schemes so they would photograph wel ...

Steam Locomotives Of New Zealand
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

NZR G Class (1928)
The NZR G class was a type of Garratt steam locomotive used in New Zealand, the only such Garratt type steam locomotives ever used by the New Zealand Railways (NZR). They were ordered to deal with traffic growth over the 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. Introduction About 1913, General Manager E H Hiley considered the importing of 10 articulated Garratt engines and 10 Pacifics; however, with the success of the AB class and WAB class Pacifics no more was heard of Garratts. Then with the retirement in 1925 of the Chief Mechanical Engineer E E Gillon his successor G S Lynde invited Beyer, Peacock & Company of England to suggest a suitable Garrett for the NIMT, and they were then asked to quote for engines with either four or six cylinders. But the three six-cylinder e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NZR AB Class
The NZR AB class was a class of 4-6-2 Pacific tender steam locomotive that operated on New Zealand's national railway system for New Zealand Railways (NZR). Originally an improvement on the 1906 A class, 141 were built between 1915 and 1927 by NZR's Addington Workshops, A & G Price of Thames, New Zealand, and North British Locomotive Company, making the AB class the largest class of steam locomotives ever to run in New Zealand. An additional eleven were rebuilt from the tank version of the AB – the WAB class – between 1947 and 1957. Two North British-made locomotives were lost in the wreck of the ''SS Wiltshire'' in May 1922. Construction and design The genesis of the AB class originated from the construction of A class 4-6-2 No. 409 at Addington Railway Workshops in 1906. A two-cylinder simple-expansion locomotive, 409 was initially classified AB to differentiate it from the four-cylinder compound A and AD class locomotives, which were by and large of a similar design ...

NZR AA 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. Introduction and design Built to a similar but vastly improved design to the Q class of 1901, they had a wheel arrangement of 4-6-2 and were suited to hauling freight services in the North Island (Originally they were to be classed QB but as they were to supplement the A class, given their aforementioned designation.) The United States built locomotives were an urgent order needed due to heavy demand with both New Zealand and British workshops unable to supply as the First World War was draining resources and manpower for the war effort. Construction was completed less than two months after the order was placed and all ten entered service in New Zealand in June 1915. Bar frames were used by the American builders instead of NZR's preferred plate frames, and the class had superh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NZR A Class (1906)
The NZR A class were a class of steam locomotives built in 1906 with a 4-6-2 wheel arrangement for the New Zealand Railways Department (NZR). The class should not be confused with the older and more obscure A class of 1873. They were designed by the NZR's Chief Mechanical Engineer, A. L. Beattie and his Chief Draughtsman, G. A. Pearson to replace less powerful locomotives struggling with increasing loads on the South Island Main Trunk Railway, and in anticipation of the traffic volumes that would be created upon the completion of the North Island Main Trunk railway. Origin and design The Baldwin Q had established the Pacific as the way forward for Express passenger locomotives, but the C.M.E decided that greater efficiency was needed. The new locomotives were therefore designed as compounds. The Vauclain system had proved ineffective in New Zealand so the type attributed to Frenchman Alfred de Glehn was adopted. The first four had Stephenson valve gear inside and Walschaerts ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Coast, New Zealand
The West Coast ( mi, Te Tai Poutini, lit=The Coast of Poutini, the Taniwha) is a regions of New Zealand, region of New Zealand on the west coast of the South Island that is administered by the West Coast Regional Council, and is known co-officially as Te Tai Poutini. It comprises the Territorial authorities of New Zealand, territorial authorities of Buller District, Grey District and Westland District. The principal towns are Westport, New Zealand, Westport, Greymouth and Hokitika. The region, one of the more remote areas of the country, is also the most sparsely populated. With a population of just 32,000 people, Te Tai Poutini is the least populous region in New Zealand, and it is the only region where the population is declining. The region has a rich and important history. The land itself is ancient, stretching back to the Carboniferous period; this is evident by the amount of carboniferous materials naturally found there, especially coal. First settled by Ngāi Tahu, Kāi T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otago
Otago (, ; mi, Ōtākou ) is a region of New Zealand located in the southern half of the South Island administered by the Otago Regional Council. It has an area of approximately , making it the country's second largest local government region. Its population was The name "Otago" is the local southern Māori dialect pronunciation of "Ōtākou", the name of the Māori village near the entrance to Otago Harbour. The exact meaning of the term is disputed, with common translations being "isolated village" and "place of red earth", the latter referring to the reddish-ochre clay which is common in the area around Dunedin. "Otago" is also the old name of the European settlement on the harbour, established by the Weller Brothers in 1831, which lies close to Otakou. The upper harbour later became the focus of the Otago Association, an offshoot of the Free Church of Scotland, notable for its adoption of the principle that ordinary people, not the landowner, should choose the ministe ...
