NYC Mohawk
The New York Central Railroad (NYC) called the 4-8-2 type of steam locomotive the Mohawk type. It was known as the ''Mountain'' type on other roads, but the New York Central did not see the name as fitting on its famous Water Level Route. Instead, it picked the name of one of those rivers its rails followed, the Mohawk River, to name its newest type of locomotive. The L1s and L2s were unstable at higher speeds due to the lack of effective cross-balancing, making the 4-wheel leading truck simply a better distributor of their weight; the L1s and L2s were consequently limited to , though this issue was resolved for the L3s and L4s using data gathered from two experimental L-2s. The New York Central became the largest 4-8-2 user in North America, with 600 locomotives of this type built for its service; only the Pennsylvania Railroad came close, with 301 M1's of the type. The Mohawk type was the pre-eminent freight power of the network, displacing the 2-8-2 type from first-line s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Locomotive Company
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer that operated from 1901 to 1969, initially specializing in the production of locomotives but later diversifying and fabricating at various times diesel generators, automobiles, steel, tanks, munitions, oil-production equipment, as well as heat exchangers for nuclear power plants. The company was formed by the merger of seven locomotive manufacturers and Schenectady Locomotive Works, Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962. After World War II, Alco closed all of its manufacturing plants except those in Schenectady and Montreal. In 1955, the company changed its name to Alco Products, Incorporated. In 1964, the Worthington Corporation acquired the company. The company wen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tender (locomotive)
A tender is a special railroad car, rail vehicle hauled by a steam locomotive containing its fuel (wood fuel, wood, coal, fuel oil, oil or torrefaction, 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 Gangway connection#Locomotives (corridor tenders), 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 (haulage), drawbar to a tender that carries the water and fuel. The fuel source used depends on what is ...

New York Central Hudson
The New York Central Hudson was a popular 4-6-4 "4-6-4, Hudson" type steam locomotive built by the American Locomotive Company (ALCO), Baldwin Locomotive Works and the Lima Locomotive Works in three series from 1927 to 1938 for the New York Central Railroad. Named after the Hudson River, the 4-6-4 wheel arrangement came to be known as the "Hudson" type in the United States, as these locomotives were the first examples built and used in North America. Built for high-speed passenger train work, the Hudson locomotives were famously known for hauling the New York Central's crack passenger trains, such as the ''20th Century Limited'' and the ''Empire State Express''. With the onset of diesel locomotives by the mid-20th Century, all Hudson locomotives were retired and subsequently scrapped by 1957, except for the tender (rail), tender from J-1d 5313, which is preserved at the Steamtown National Historic Site in Scranton, Pennsylvania.

Hugh Llewelyn 2933 (5961707796)
Hugh is the English-language variant of the masculine given name , itself the Old French variant of '' Hugo (name)">Hugo'', a short form of Continental Germanic Germanic name">given names beginning in the element "mind, spirit" (Old English ). The Germanic name is on record beginning in the 8th century, in variants ''Chugo, Hugo, Huc, Ucho, Ugu, Uogo, Ogo, Ougo,'' etc. The name's popularity in the Middle Ages ultimately derives from its use by Frankish nobility, beginning with Duke of the Franks and Count of Paris Hugh the Great (898–956). The Old French form was adopted into English from the Norman period (e.g. Hugh of Montgomery, 2nd Earl of Shrewsbury d. 1098; Hugh d'Avranches, 1st Earl of Chester, d. 1101). The spelling ''Hugh'' in English is from the Picard variant spelling '' Hughes'', where the orthography ''-gh-'' takes the role of ''-gu-'' in standard French, i.e. to express the phoneme /g/ as opposed to the affricate /ʒ/ taken by the grapheme ''g'' before front ...

Crank Axle
A crank is an arm attached at a right angle to a rotating shaft by which circular motion is imparted to or received from the shaft. When combined with a connecting rod, it can be used to convert circular motion into reciprocating motion, or vice versa. The arm may be a bent portion of the shaft, or a separate arm or disk attached to it. Attached to the end of the crank by a pivot is a rod, usually called a connecting rod (conrod). The term often refers to a human-powered crank which is used to manually turn an axle, as in a bicycle crankset or a brace and bit drill. In this case a person's arm or leg serves as the connecting rod, applying reciprocating force to the crank. There is usually a bar perpendicular to the other end of the arm, often with a freely rotatable handle or pedal attached. Examples Familiar examples include: Hand-powered cranks * Spinning wheel * Mechanical pencil sharpener * Fishing reel and other reels for cables, wires, ropes, etc. *Starting handle ...

Main Rod
A connecting rod, also called a 'con rod', is the part of a piston engine which connects the piston to the crankshaft. Together with the crank, the connecting rod converts the reciprocating motion of the piston into the rotation of the crankshaft. The connecting rod is required to transmit the compressive and tensile forces from the piston. In its most common form, in an internal combustion engine, it allows pivoting on the piston end and rotation on the shaft end. The predecessor to the connecting rod is a mechanic linkage used by water mills to convert rotating motion of the water wheel into reciprocating motion. The most common usage of connecting rods is in internal combustion engines or on steam engines. __TOC__ Origins A connecting rod crank has been found in the Celtic Oppida at Paule in Brittany, dated to 69 BC. The predecessor to the connecting length is the mechanical linkage used by Roman-era watermills. An early example of this linkage has been found at the ...

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 posit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cylinder (engine)
In an engine, the cylinder is the space in which a piston travels. The inner surface of the cylinder is formed from either a thin metallic liner (also called "sleeve") or a surface coating applied to the engine block. A piston is seated inside each cylinder by several metal piston rings, which also provide seals for compression and the lubricating oil. The piston rings do not actually touch the cylinder walls, instead they ride on a thin layer of lubricating oil. Steam engines The cylinder in a steam engine is made pressure-tight with end covers and a piston; a valve distributes the steam to the ends of the cylinder. Cylinders were cast in cast iron and later in steel. The cylinder casting can include other features such as valve ports and mounting feet. Internal combustion engines The cylinder is the space through which the piston travels, propelled by the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an air-cooled e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-6-6-2
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, a is a locomotive with one pair of unpowered leading wheels, followed by two sets of three pairs of powered driving wheels and one pair of trailing wheels. The wheel arrangement was principally used on Mallet locomotive, Mallet-type articulated locomotives, although some tank locomotive examples were also built. A Garratt locomotive or Golwé locomotive with the same wheel arrangement is designated since both engine units are pivoting. Under the UIC classification the wheel arrangement is referred to as (1'C)C1' for Mallet locomotives. Overview The first locomotives of the 2-6-6-2 wheel arrangement were built in 1906 by the Great Northern Railway to permit longer trains on their heavily graded line over the Cascade Mountains.Drury, p. 181. They were a refinement of the first North American Mallets, 0-6-6-0 engines built for the Baltimore & Ohio in 1904, with leading and trailing trucks to ...

Great Depression
The Great Depression was a severe global economic downturn from 1929 to 1939. The period was characterized by high rates of unemployment and poverty, drastic reductions in industrial production and international trade, and widespread bank and business failures around the world. The economic contagion began in 1929 in the United States, the largest economy in the world, with the devastating Wall Street stock market crash of October 1929 often considered the beginning of the Depression. Among the countries with the most unemployed were the U.S., the United Kingdom, and Weimar Republic, Germany. The Depression was preceded by a period of industrial growth and social development known as the "Roaring Twenties". Much of the profit generated by the boom was invested in speculation, such as on the stock market, contributing to growing Wealth inequality in the United States, wealth inequality. Banks were subject to laissez-faire, minimal regulation, resulting in loose lending and wides ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Booster Engine
A locomotive booster for steam locomotives is a small supplementary two-cylinder steam engine back-gear-connected to the trailing truck axle on the locomotive or one of the trucks on the tender. It was invented in 1918 by Howard L. Ingersoll, assistant to the president of the New York Central Railroad. A rocking idler gear permits the booster engine to be put into operation by the driver (engineer). A geared booster engine drives one axle only and can be non-reversible, with one idler gear, or reversible, with two idler gears. There were variations built by the Franklin company which utilized side rods to transmit tractive force to all axles of the booster truck. These rod boosters were predominately used on the leading truck of the tender, though there is an example of a Lehigh Valley 4-8-4 using it as a trailing tender truck. A booster engine is used to start a heavy train or maintain low speed under demanding conditions. Rated at about at speeds from , it can be cut in ...
