McGregor And Company
McGregor and Company Ltd was a heavy engineering company based in Dunedin, New Zealand. Apart from building the notable steam ship '' Earnslaw'', the company also built early 20th century steam locomotives, of which there are no survivors. The company's factory was located in Thomas Burns Street, directly across the railway tracks from the city's railway station Rail transport (also known as train transport) is a means of transport that transfers passengers and goods on wheeled vehicles running on rails, which are incorporated in tracks. In contrast to road transport, where the vehicles run on a prep .... References History of Dunedin Engineering companies of New Zealand {{NewZealand-company-stub ...

Engineering
Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering. The term ''engineering'' is derived from the Latin ''ingenium'', meaning "cleverness" and ''ingeniare'', meaning "to contrive, devise". Definition The American Engineers' Council for Professional Development (ECPD, the predecessor of ABET) has defined "engineering" as: The creative application of scientific principles to design or develop structures, machines, apparatus, or manufacturing processes, or works utilizing them singly or in combination; or to construct or operate the same with full cognizance of their design; or to forecast their behavior under speci ...

Dunedin
Dunedin ( ; mi, Ōtepoti) is the second-largest city in the South Island of New Zealand (after Christchurch), and the principal city of the Otago region. Its name comes from , the Scottish Gaelic name for Edinburgh, the capital of Scotland. The city has a rich Scottish, Chinese and Māori heritage. With an estimated population of as of , Dunedin is both New Zealand's seventh-most populous metro and urban area. For historic, cultural and geographic 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, and 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. Archaeological evidence points to lengthy occupation of the area by Māori prior to the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
TSS Earnslaw
The TSS ''Earnslaw'' is a 1912 Edwardian twin screw steamer based at Lake Wakatipu in New Zealand. It is one of the oldest tourist attractions in Central Otago, and the only remaining commercial passenger-carrying coal-fired steamship in the southern hemisphere. History At the beginning of the twentieth century, New Zealand Railways (NZR) awarded a £20,850-pound contract to John McGregor and Company shipbuilders of Dunedin to build a steamship for Lake Wakatipu at their Otago foundry and engineering works. The ''Earnslaw'' was designed by naval architect Hugh McRae and was based on a Siemens-Martin steel hull design and using Kauri for the decking. Propulsion was provided by twin coal-fired triple-expansion, jet-condensing, vertically inclined engines. The keel was laid on 4 July 1911. The ship was named after Mount Earnslaw, a 2889-metre peak at the head of Lake Wakatipu. She was to be 51.2 metres long, the biggest boat on the lake, and the largest steamship built in N ...

Steam Locomotive
A steam locomotive is a locomotive that provides the force to move itself and other vehicles by means of the expansion of steam. It is fuelled by burning combustible material (usually coal, oil or, rarely, wood) to heat water in the locomotive's boiler to the point where it becomes gaseous and its volume increases 1,700 times. Functionally, it is a steam engine on wheels. In most locomotives, the steam is admitted alternately to each end of its cylinders, in which pistons are mechanically connected to the locomotive's main wheels. Fuel and water supplies are usually carried with the locomotive, either on the locomotive itself or in a tender coupled to it. Variations in this general design include electrically-powered boilers, turbines in place of pistons, and using steam generated externally. Steam locomotives were first developed in the United Kingdom during the early 19th century and used for railway transport until the middle of the 20th century. Richard Trevith ...

History Of Dunedin
The villages and then city that lay at the head of Otago Harbor never existed in isolation, but have always been a staging ground between inland Otago and the wider world. While Dunedin's current official city limits extend north to Waikouaiti, inland to Middlemarch and south to the Taieri River mouth, this articles focus is the history of the Dunedin urban area, only mentioning Mosgiel, the Otago Peninsula, Port Chalmers and inland Otago for context. Archaeological evidence shows the first Māori occupation of the wider Dunedin area occurred within decades of their arrival in New Zealand (1280–1320). The population at this time was concentrated along the southern coast and they relied on seals and to a lesser extent moa for the bulk of their food. With reduced moa and seal numbers the population slumped. Elsewhere in New Zealand it grew again with the evolution of the horticulture based Classic culture, necessitating fortified villages (pā). However, this culture did no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
