New York Central 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 didn't 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. Despite the more common name, the 4-8-2 was actually suited in many ways more to flatland running than slow mountain slogging, with its 4-wheel leading truck for stability at speed. However, the L1s and L2s were unstable at higher speeds due to the design of their reciprocating gear, making the 4-wheel leading truck simply a better distributor of the locomotives weight; the L1s and L2s were consequently limited to , but this issue was resolved for the L3s and L4s. Indeed, the New York Central became the largest user of this wheel arrangement in North America, with 600 locomotives of this type built for its service; only ...

American Locomotive Company
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969. The company was formed by the merger of seven smaller 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. The company changed its name to Alco Products, Incorporated in 1955. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969. The ALCO name is currently being used by Fairbanks-Morse, Fairbanks Morse Engine for their FM, ALCO line. Foundation and early history The company was created in 1901 from the merger of seven smaller locomotive manufacturers with Schenectady Locomotive Works, Schenect ...

Roller 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 ...

New York Central Hudson
A New York Central Hudson was a popular 4-6-4 "Hudson" type steam locomotive built by the American Locomotive Company (ALCO) 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, with none preserved today except for a converted tender from J-1d 5313, which is preserved at the Steamtown National Historic Site in Scranton, Pennsylvania.

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. *Starti ...

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 The predecessor to the connecting length is the mechanical linkage used by Roman-era watermills. The earliest known example of this linkage has been found at the late 3rd century Hierapolis sawmill in Roman Asia (modern Turkey) and the 6th century s ...

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] |
Cylinder (engine)
In a reciprocating 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 to the energy generated from the combustion of the air/fuel mixture in the combustion chamber. In an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Booster Engine
A booster engine for steam locomotives is a small two-cylinder steam engine back-gear-connected to the trailing truck axle on the locomotive or the lead truck on the tender. A rocking idler gear permits it to be put into operation by the driver (engineer). It drives one axle only and can be non-reversible, with one idler gear, or reversible, with two idler gears. A booster engine is used to start a heavy train or maintain low speed under demanding conditions. Rated at about at speeds of from , it can be cut in while moving at speeds under and is semi-automatically cut out via the engineer notching back the reverse gear between , depending on the model and design of the booster. A tractive effort of is common, although ratings of up to around were possible. Tender boosters are equipped with side-rods connecting axles on the lead truck. Such small side-rods restrict speed and are therefore confined to switching locomotives, often used in transfer services between yards. Tende ...
