Pacific Type
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, six powered and coupled driving wheels on three axles and two trailing wheels on one axle. The locomotive became almost globally known as a Pacific type after a locomotive built by the Baldwin Locomotive Works in Philadelphia was shipped across the Pacific Ocean to New Zealand. Overview The introduction of the design in 1901 has been described as "a veritable milestone in locomotive progress". On many railways worldwide, Pacific steam locomotives provided the motive power for express passenger trains throughout much of the early to mid-20th century, before either being superseded by larger types in the late 1940s and 1950s, or replaced by electric locomotive, electric or diesel locomotive, diesel-electric locomotives during the 1950s and 1960s. Nevertheless, new Pacific designs continued to be built until the mid-1950s. The type is genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
NZR Q Class (1901)
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 made 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 requirement ...

Trailing Wheel
On a steam locomotive, a trailing wheel or trailing axle is generally an unpowered wheel or axle (Wheelset (rail transport), wheelset) located behind the driving wheels. The axle of the trailing wheels is usually located in a trailing Bogie, truck. On some large locomotives, a booster engine was mounted on the trailing truck to provide extra tractive effort when starting a heavy train and at low speeds on gradients. Trailing wheels were used in some early locomotives but fell out of favor for a time during the latter 19th century. As demand for more powerful locomotives increased, trailing wheels began to be used to support the crew cab and rear firebox area. Trailing wheels first appeared on American locomotives between 1890 and 1895, but their axle worked in rigid pedestals. It enabled boilers to be lowered, since the top of the main frames was dropped down behind the driving wheels and under the firebox. The firebox could also be longer and wider, increasing the heating su ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South African Class 5A 4-6-2
The South African Railways Class 5A 4-6-2 of 1903 was a steam locomotive from the pre- Union era in the Cape of Good Hope. In 1903, the Cape Government Railways placed two Karoo Class steam locomotives with a Pacific type wheel arrangement in passenger service. In 1912, when they were assimilated into the South African Railways, they were renumbered and designated Class 5A.Espitalier, T.J.; Day, W.A.J. (1944).

Kitson & Company
Kitson and Company was a locomotive manufacturer based in Hunslet, Leeds, West Yorkshire, England. Early history The company was started in 1835 by James Kitson (businessman), James Kitson at the Airedale Foundry, off Pearson Street, Hunslet, with Charles Todd as a partner. Todd had been apprenticed to Matthew Murray at the Round Foundry in Holbeck, Leeds. Initially, the firm made parts for other builders, until it was joined in 1838 by David Laird, a wealthy farmer who was looking for investments, and the company became Todd, Kitson and Laird. That year saw the production of the company's first complete locomotives, either for the North Midland Railway, North Midland or the Liverpool and Manchester Railway. However, Todd left almost immediately to form Railway Foundry, Shepherd and Todd, and the company was known variously as Kitson and Laird or Laird and Kitson. The order for six engines by the Liverpool and Manchester began with ''LMR 57 Lion, Lion'', which still exists. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cape Colony
The Cape Colony (), also known as the Cape of Good Hope, was a British Empire, British colony in present-day South Africa named after the Cape of Good Hope. It existed from 1795 to 1802, and again from 1806 to 1910, when it united with three other colonies to form the Union of South Africa, then became the Cape Province, which existed even after 1961, when South Africa had become a republic, albeit, temporarily outside the Commonwealth of Nations (1961–94). The British colony was preceded by an earlier corporate colony that became an Dutch Cape Colony, original Dutch colony of the same name, which was established in 1652 by the Dutch East India Company, Dutch East India Company (VOC). The Cape was under VOC rule from 1652 to 1795 and under rule of the Napoleonic Batavian Republic, Batavia Republic from 1803 to 1806. The VOC lost the colony to Kingdom of Great Britain, Great Britain following the 1795 Invasion of the Cape Colony, Battle of Muizenberg, but it was ceded to the ...

Missouri Pacific Railroad
The Missouri Pacific Railroad , commonly abbreviated as MoPac, was one of the first railroads in the United States west of the Mississippi River. MoPac was a Class I railroad growing from dozens of predecessors and mergers. In 1967, the railroad operated 9,041 miles of road and 13,318 miles of track, not including Wikipedia:WikiProject_Trains/ICC_valuations/Doniphan,_Kensett_and_Searcy_Railway, DK&S, New Orleans and Gulf Coast Railway, NO&LC, Texas_and_Pacific_Railway, T&P, and its subsidiaries C&EI and Missouri-Illinois Railroad, Missouri-Illinois. Union Pacific Corporation, the parent company of the Union Pacific Railroad, agreed to buy the Missouri Pacific Railroad on January 8, 1980. Lawsuits filed by competing railroads delayed approval of the merger until September 13, 1982. After the Supreme Court denied a trial to the Southern Pacific Transportation Company, Southern Pacific, the merger took effect on December 22, 1982. However, due to outstanding bonds of the Missouri Paci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Island
The South Island ( , 'the waters of Pounamu, Greenstone') is the largest of the three major islands of New Zealand by surface area, the others being the smaller but more populous North Island and Stewart Island. It is bordered to the north by Cook Strait, to the west by the Tasman Sea, to the south by the Foveaux Strait and Southern Ocean, and to the east by the Pacific Ocean. The South Island covers , making it the List of islands by area, world's 12th-largest island, constituting 56% of New Zealand's land area. At low altitudes, it has an oceanic climate. The most populous cities are Christchurch, Dunedin, Nelson, New Zealand, Nelson and Invercargill. Prior to European settlement, Te Waipounamu was sparsely populated by three major iwi – Kāi Tahu, Kāti Māmoe, and the historical Waitaha (South Island iwi), Waitaha – with major settlements including in Kaiapoi Pā near modern-day Christchurch. During the Musket Wars expanding iwi colonised Te Tau Ihu Māori, Te Tau Ihu, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lignite
Lignite (derived from Latin ''lignum'' meaning 'wood'), often referred to as brown coal, is a soft, brown, combustible sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35% and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture, which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation. Lignite combustion produces less heat for the amount of carbon dioxide and sulfur released than other ranks of coal. As a result, lignite is the most harmful coal to human health. Depending on the source, various toxic heavy metals, including naturally occurring radioactive materials, may be present in lignite and left over in the coal fly ash produced from its combustion, further increasing health risks. Characteristics Lignite is brownish-bl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wootten Firebox
The Wootten firebox is a type of firebox used on steam locomotives. The firebox was very wide to allow combustion of anthracite waste, known as " culm". Its size necessitated unusual placement of the crew, examples being camelback locomotives. The Wootten firebox made for a free-steaming, powerful locomotive, and the cheap fuel burned almost smokelessly; the combination made for an excellent passenger locomotive, and many camelbacks operated in this service. History John E. Wootten was the Superintendent of Motive Power for the then Philadelphia and Reading Railroad (later simply the Reading Railroad) from 1866, and General Manager of the system from 1876. He saw the vast spoil tips (piles of anthracite waste) in the area as a possible plentiful, cheap source of fuel if he could develop a firebox that could burn it effectively. Through experiments, he determined that a large, wide firebox with a slow firing rate worked best, with a thin layer of the fuel and moderate draft. ...

Milwaukee Road
The Chicago, Milwaukee, St. Paul and Pacific Railroad (CMStP&P), better known as the Milwaukee Road , was a Class I railroad that operated in the Midwestern United States, Midwest and Pacific Northwest, Northwest of the United States from 1847 until 1986. The company experienced financial difficulty through the 1970s and 1980s, including bankruptcy in 1977 (though it filed for bankruptcy twice in 1925 and 1935, respectively). In 1980, it abandoned its Pacific Extension, which included track in the states of Montana, Idaho, and Washington (state), Washington. The remaining system was merged into the Soo Line Railroad , a subsidiary of Canadian Pacific Railway , on January 1, 1986. Much of its historical trackage remains in use by other railroads. The company brand is commemorated by buildings like the historic Minneapolis station (Milwaukee Road), Milwaukee Road Depot in Minneapolis and preserved locomotives such as Milwaukee Road 261 which operates excursion trains.

LNER Class A4 4468 Mallard
LNER Class A4 4468 ''Mallard'' is a 4-6-2 ("Pacific") steam locomotive built in 1938 for operation on the London and North Eastern Railway (LNER) at Doncaster Works to a design of Nigel Gresley. Its streamlined, wind tunnel tested design allowed it to haul long-distance express passenger services at high speeds. On 3 July 1938, ''Mallard'' broke the world speed record for steam locomotives at , which still stands today. While in British Railways days regular steam-hauled rail services in the UK were officially limited to a 'line speed', before the war, the A4s had to run significantly above just to keep schedule on trains such as the ''Silver Jubilee'' and '' The Coronation'', with the engines reaching 100 mph on many occasions. ''Mallard'' covered almost one and a half million miles (2.4 million km) before it was retired in 1963. The locomotive is long and weighs 165 long tons (168 tonnes, 369,600 lbs), including the tender. It is painted in LNER garter blue with ...

Firebox (steam Engine)
In a steam engine, the firebox is the area where the fuel is burned, producing heat to boil the water in the boiler. Most are somewhat box-shaped, hence the name. The hot gases generated in the firebox are pulled through a rack of tubes running through the boiler. Steam locomotive fire tube firebox In the standard steam locomotive fire-tube boiler, the firebox is surrounded by water space on five sides. The bottom of the firebox is open to atmospheric pressure, but covered by fire grates (solid fuel) or a firing pan (liquid fuel). If the engine burns solid fuel, like wood or coal, there is a grate covering most of the bottom of the firebox to hold the fire. An ashpan, mounted underneath the firebox and below the grates, catches and collects hot embers, ashes, and other solid combustion waste as it falls through the grates. In a coal-burning locomotive, the grates may be shaken to clean dead ash from the bottom of the fire. They are shaken either manually or (in larger locomoti ...
