4-8-4 Locomotives
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, eight powered and coupled driving wheels on four axles and four trailing wheels on two axles. The type was first used by the Northern Pacific Railway, and initially named the Northern Pacific, but railfans and railroad employees have shortened the name since its introduction. It is most-commonly known as a Northern. Overview Development The wheel arrangement was a progression from the Mountain type and, like the Berkshire and Hudson types, an example of the "Super Power" concept in steam locomotive design that made use of the larger firebox that could be supported by a four-wheel trailing truck, which allowed greater production of steam. The four-wheel leading truck gave stability at speed and the eight driving wheels gave greater adhesion. The evolution to the type occurred in the United States of America soon after the Lima Loco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atchison, Topeka And Santa Fe Railway
The Atchison, Topeka and Santa Fe Railway , often referred to as the Santa Fe or AT&SF, was one of the larger railroads in the United States. The railroad was chartered in February 1859 to serve the cities of Atchison, Kansas, Atchison and Topeka, Kansas, and Santa Fe, New Mexico. The railroad reached the Kansas–Colorado border in 1873 and Pueblo, Colorado, in 1876. To create a demand for its services, the railroad set up real estate offices and sold farmland from the land grants that it was awarded by United States Congress, Congress. Despite being chartered to serve the city, the railroad chose to bypass Santa Fe, due to the engineering challenges of the mountainous terrain. Eventually Santa Fe Southern Railway, a branch line from Lamy, New Mexico, brought the Santa Fe railroad to its namesake city. The Santa Fe was a pioneer in intermodal freight transport; at various times, it operated an airline, the short-lived Santa Fe Skyway, and the fleet of Santa Fe Railroad Tugboa ...

2-8-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles and two trailing wheels on one axle, usually in a trailing truck. This configuration of steam locomotive is most often referred to as a Mikado, frequently shortened to Mike. At times it was also referred to on some railroads in the United States of America as the McAdoo Mikado and, during World War II, the MacArthur. The notation 2-8-2T indicates a tank locomotive of this wheel arrangement, the "T" suffix indicating a locomotive on which the water is carried in tanks mounted on the engine rather than in an attached tender. Overview The 2-8-2 wheel arrangement allowed the locomotive's firebox to be placed behind instead of above the driving wheels, thereby allowing a larger firebox that could be both wide and deep. This supported a greater rate of combustion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Germany

Deutsche Reichsbahn
The ''Deutsche Reichsbahn'', also known as the German National Railway, the German State Railway, German Reich Railway, and the German Imperial Railway, was the German national railway system created after the end of World War I from the regional railways of the individual states of the German Empire. The ''Deutsche Reichsbahn'' has been described as "the largest enterprise in the capitalist world in the years between 1920 and 1932"; nevertheless its importance "arises primarily from the fact that the Reichsbahn was at the center of events in a period of great turmoil in German history". Overview The company was founded on 1 April 1920 as the ("German Imperial Railways") when the Weimar Republic, which still used the nation-state term of the previous monarchy, (German Reich, hence the usage of the in the name of the railway; the monarchical term was ), took national control of the German railways, which had previously been run by the German states. In 1924 it was reorganise ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
DRB Class 06
The German DRB Class 06 engines were standard steam locomotives (''Einheitsdampflokomotiven'') with the Deutsche Reichsbahn#1937: Deutsche Reichsbahn (DRB), Deutsche Reichsbahn (DRB) designed to haul express train services. They were the only German locomotives with a 4-8-4, 4-8-4 (Northern) Whyte notation, wheel arrangement. History The two Class 06 locomotives built by the firm of Krupp in 1939 were the largest, heaviest and most powerful locomotives in the Deutsche Reichsbahn. They were built for heavy express train duties in hilly terrain. The performance requirement was for the transportation of 650 tons at 120 km/h. On ramps of 1:100 it was to still be capable of maintaining 60 km/h. The Class 06 was given the same boiler as the DRG Class 45, Class 45 and many of the same components as the DRG Class 41, Class 41. The running gear, with four coupled axles, had a wheelbase of 6,75 m. In trials, the vehicles confirmed their remarkable capability and runni ...

Baldwin Locomotive Works
The Baldwin Locomotive Works (BLW) was an American manufacturer of railroad locomotives from 1825 to 1951. Originally located in Philadelphia, it moved to nearby Eddystone, Pennsylvania, in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete as demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation. The company has no relation to the E.M. Baldwin and Sons of New South Wales, Australia, a builder of small diesel locomotives for sugar cane railroads. History: 19th century Beginning The Baldwin Locomotive Works had a humble beginning. Matthias W. Baldwin, the founder, was a jeweler and whitesmith, who, in 1825, formed a partnership with machinist David H. Mason, and engaged in the manufacture of bookbinders' tools and cylinders for cal ...

Drag Freight
A drag freight is a long, slow, high-tonnage railroad train, often carrying commodities such as coal or ore. Compared to "fast freight" trains, drag freight trains have a very low power-to-weight ratio, making them somewhat unpredictable on steep grades or hilly routes. This causes many dispatchers to be extremely conservative with how they handle drag freights, especially when they share lines with higher priority fast freights and passenger trains. Power Before and during WWI and into the 1920s, large locomotives such as the 2-8-2 Mikado or mainly larger types like Articulated locomotives were typically used for drag freight operations. After the railroads dieselized, heavy duty diesel locomotives (typically six-axle units, to improve adhesion) were used for the drag freights. Multiple unit operations allowed one person to control multiple locomotives. As many as 4-11 locomotives may be used for a heavy haul drag freight. Attempts were made to develop ultra large locomotives ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timken Company
The Timken Company is a global manufacturer of bearings and power transmission products. Timken operates from 42 countries. Company history In 1898, Henry Timken obtained a patent for an improved tapered roller bearing, and in 1899 incorporated as The Timken Roller Bearing Axle Company in St. Louis. In 1901, the company moved to Canton, Ohio, as the automobile industry began to overtake the carriage industry. Timken and his two sons chose this location because of its proximity to the American car manufacturing centers of Detroit and Cleveland and the American steel-making centers of Pittsburgh and Cleveland. In 1917, the company began its steel- and tube-making operations in Canton to vertically integrate and maintain better control over the steel used in its bearings. World War I had created an increase in demand for steel, affecting its supply and price in the market. Timken entered international markets in the early 1900s, establishing a presence initially in Great Brit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rolling-element Bearing
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing, is a bearing which carries a load by placing rolling elements (such as balls or rollers) between two concentric, grooved rings called races. The relative motion of the races causes the rolling elements to roll with very little rolling resistance and with little sliding. One of the earliest and best-known rolling-element bearings are sets of logs laid on the ground with a large stone block on top. As the stone is pulled, the logs roll along the ground with little sliding friction. As each log comes out the back, it is moved to the front where the block then rolls on to it. It is possible to imitate such a bearing by placing several pens or pencils on a table and placing an item on top of them. See " bearings" for more on the historical development of bearings. A rolling element rotary bearing uses a shaft in a much larger hole, and cylinders called "rollers" tightly fill the space between t ...

Valve Gear
The valve gear of a steam engine is the mechanism that operates the inlet and exhaust valves to admit steam into the cylinder and allow exhaust steam to escape, respectively, at the correct points in the cycle. It can also serve as a reversing gear. It is sometimes referred to as the "motion". Purpose In the simple case, this can be a relatively simple task as in the internal combustion engine in which the valves always open and close at the same points. This is not the ideal arrangement for a steam engine, though, because greatest power is achieved by keeping the inlet valve open throughout the power stroke (thus having full boiler pressure, minus transmission losses, against the piston throughout the stroke) while peak efficiency is achieved by only having the inlet valve open for a short time and then letting the steam expand in the cylinder (expansive working). The point at which steam stops being admitted to the cylinder is known as the '' cutoff'', and the optimal positio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fireman (steam Engine)
A fireman, stoker or watertender is a person whose occupation it is to tend the fire for the running of a boiler, heating a building, or powering a steam engine. Much of the job is hard physical labor, such as shoveling fuel, typically coal, into the boiler's firebox. On steam locomotives the title ''fireman'' is usually used, while on steamships and stationary steam engines, such as those driving saw mills, the title is usually ''stoker'' (although the British Merchant Navy did use ''fireman''). The German word ''Heizer'' is equivalent and in Dutch the word ''stoker'' is mostly used too. The United States Navy referred to them as ''watertenders''. Nautical Royal Navy The Royal Navy used the rank structure ordinary stoker, stoker, leading stoker, stoker petty officer and chief stoker. The non-substantive (trade) badge for stokers was a ship's propeller. Stoker remains the colloquial term used to refer to a marine engineering rating, despite the decommissioning of the la ...
