Onward (locomotive)
The steam locomotive ''Onward'' had polygonal driving wheels. This rather ineffective locomotive with only one driving axle was built in 1887 by the Hinkley Locomotive Works in Boston for the Swinerton Locomotive Driving Wheel Company. History In 1887, the Swinerton Locomotive Driving Wheel Company in the United States received a unique locomotive boldly called ''Onward'', which had been built by the Hinkley Locomotive Works of Boston. Its unique feature was that its wheels were not round. The company's founder, C. E. Swinerton, had specified that both drivin ...[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hinkley Locomotive Works
Hinkley Locomotive Works was a steam locomotive manufacturer based in Boston, Massachusetts in the 19th century. History The company that was to become known as Hinkley Locomotive Works got its start in Boston in 1831. Holmes Hinkley and his partner Daniel F. Child founded the Boston Machine Works and soon built the third stationary steam engine that was constructed in Massachusetts. The company's first locomotive was a 4-2-0 built in 1840 that followed the roughly standard designs of the 1830s. Hinkley's early locomotives closely resembled those designed by John Souther. The company gained a reputation as a reliable and respectable locomotive builder and grew to become the largest manufacturer in New England within a decade. In 1848 the company reorganized as the Boston Locomotive Works and operated under that name until foreclosure due to the financial panic in 1859. After reorganization under Jarvis Williams, the company became Hinkley, Williams and Company. Hinkley, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boston
Boston (), officially the City of Boston, is the state capital and most populous city of the Commonwealth of Massachusetts, as well as the cultural and financial center of the New England region of the United States. It is the 24th- most populous city in the country. The city boundaries encompass an area of about and a population of 675,647 as of 2020. It is the seat of Suffolk County (although the county government was disbanded on July 1, 1999). The city is the economic and cultural anchor of a substantially larger metropolitan area known as Greater Boston, a metropolitan statistical area (MSA) home to a census-estimated 4.8 million people in 2016 and ranking as the tenth-largest MSA in the country. A broader combined statistical area (CSA), generally corresponding to the commuting area and including Providence, Rhode Island, is home to approximately 8.2 million people, making it the sixth most populous in the United States. Boston is one of the oldest ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

4-2-2
Under the Whyte notation for the classification of steam locomotives, 4-2-2 represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle, and two trailing wheels on one axle. Other equivalent classifications are: :UIC classification: 2A1 :French classification: 211 :Turkish classification: 14 :Swiss classification: 1/4 Like other steam locomotive types with single pairs of driving wheels, they were also known as singles. History The 4-2-2 configuration offered designers eight wheels to spread the weight of a larger locomotive, but prior to the bogies (invented in 1830s) becoming popular, created a long rigid wheelbase with limited adhesion. As a result, the type was relatively rare until the 1870s. The first steam locomotive made by Borsig of Berlin in 1841, the ''Borsig'' No 1, was a 4-2-2, but the company quickly reverted to the more common 2-2-2 configuration.

Portland & Rochester Railroad
The Portland & Rochester Railroad, established in 1867, was an important predecessor railway of the Rochester to Portland branch line of the Boston and Maine Railroad. It was founded in the merger of several smaller shortline rail transport companies, the oldest being the shortline York and Cumberland Railroad which was formed in 1846 to connect the seaport facilities of Portland, Maine, to the water powered manufacturing and textile industries along the Quampheagan Falls on the Salmon Falls River in the twin towns of South Berwick, Maine, and Rollinsford, New Hampshire (ca 1850). A year later another investor group began a railway leading inland to the upcoming mill town of Nashua, New Hampshire, inspiring the easier to construct leg founded as the Nashua & Rochester Railroad (1847). The York and Cumberland opened to Gorham, Maine, in 1851 under the direction of Maine railroad pioneer John A. Poor and was extended in 1853. The York and Cumberland was reorganized as the ''Portl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotives Of The United States
Steam is a substance containing water in the gas phase, and sometimes also an aerosol of liquid water droplets, or air. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Steam that is saturated or superheated is invisible; however, "steam" often refers to wet steam, the visible mist or aerosol of water droplets formed as water vapor condenses. Water increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapor pressure, it can create a steam explosion. Types ...

Rolling Stock Innovations
Rolling is a type of motion that combines rotation (commonly, of an axially symmetric object) and translation of that object with respect to a surface (either one or the other moves), such that, if ideal conditions exist, the two are in contact with each other without sliding. Rolling where there is no sliding is referred to as ''pure rolling''. By definition, there is no sliding when there is a frame of reference in which all points of contact on the rolling object have the same velocity as their counterparts on the surface on which the object rolls; in particular, for a frame of reference in which the rolling plane is at rest (see animation), the instantaneous velocity of all the points of contact (e.g., a generating line segment of a cylinder) of the rolling object is zero. In practice, due to small deformations near the contact area, some sliding and energy dissipation occurs. Nevertheless, the resulting rolling resistance is much lower than sliding friction, and thus, ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
4-2-2 Locomotives
A coxless four is a rowing boat used in the sport of competitive rowing. It is designed for four persons who propel the boat with sweep oars, without a coxswain. The crew consists of four rowers, each having one oar. There are two rowers on the stroke side (rower's right hand side) and two on the bow side (rower's lefthand side). There is no coxswain, but the rudder is controlled by one of the crew, normally with the rudder cable attached to the toe of one of their shoes which can pivot about the ball of the foot, moving the cable left or right. The steersman may row at bow, who has the best vision when looking over their shoulder, or on straighter courses stroke may steer, since they can point the stern of the boat at some landmark at the start of the course. The equivalent boat when it is steered by a coxswain is called a "coxed four". Racing boats (often called "shells") are long, narrow, and broadly semi-circular in cross-section with gradual tapers, causing little dra ...

Railway Locomotives Introduced In 1887
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 prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run. Tracks usually consist of steel rails, installed on sleepers (ties) set in ballast, on which the rolling stock, usually fitted with metal wheels, moves. Other variations are also possible, such as "slab track", in which the rails are fastened to a concrete foundation resting on a prepared subsurface. Rolling stock in a rail transport system generally encounters lower frictional resistance than rubber-tyred road vehicles, so passenger and freight cars (carriages and wagons) can be coupled into longer trains. The operation is carried out by a railway company, providing transport between train stations or freight customer faciliti ...
