4-2-0 (song)
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of four leading wheels on two axles, two powered driving wheels on one axle and no trailing wheels. This type of locomotive is often called a Jervis type, the name of the original designer. Overview The wheel arrangement type was common on United States railroads from the 1830s through the 1850s. The first to be built was the ''Experiment'', later named ''Brother Jonathan'', for the Mohawk and Hudson Railroad in 1832. It was built by the West Point Foundry based on a design by John B. Jervis. Having little else to reference, the manufacturers patterned the boiler and valve gear after locomotives built by Robert Stephenson of England. A few examples of Stephenson locomotives were already in operation in America, so engineers did not have to travel too far to get their initial ideas. In England, the was developed around 1840 from the 2-2-2 design of Stephenson's first Long B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hackensack And New York Railroad
The Hackensack and New York Railroad was a New Jersey railroad company which was chartered in 1856. The railway ran from Rutherford, New Jersey to Hackensack, New Jersey and service started in 1858. Construction along a northward extension of the line known as the Hackensack and New York Extension Railroad under the leadership of David P. Patterson started in 1866. Service to Hillsdale opened on March 4, 1870. The company is said to have gone into receivership by 1878 and reorganized as the New Jersey and New York Railroad, extended into Rockland County, New York and leased by the Erie Railroad in 1896. The track right of way is now New Jersey Transit's Pascack Valley Line The Pascack Valley Line is a commuter rail line operated by the Hoboken Division of New Jersey Transit, in the United States. The line runs north from Hoboken Terminal, through Hudson County and Bergen County in New Jersey, and into Rockland Co .... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smokebox
A smokebox is one of the major basic parts of a steam locomotive exhaust system. Smoke and hot gases pass from the firebox through tubes where they pass heat to the surrounding water in the boiler. The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney (or funnel). Early locomotives had no smokebox and relied on a long chimney to provide natural draught for the fire but smokeboxes were soon included in the design for two specific reasons. Firstly and most importantly, the blast of exhaust steam from the cylinders, when directed upwards through an airtight smokebox with an appropriate design of exhaust nozzle, effectively draws hot gases through the boiler tubes and flues and, consequently, fresh combustion air into the firebox. Secondly, the smokebox provides a convenient collection point for ash and cinders ("char") drawn through the boiler tubes, which can be easily cleaned out at the end of a working day. Without a smokebox, all char must ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Engineer
Engineers, as practitioners of engineering, are professionals who invent, design, analyze, build and test machines, complex systems, structures, gadgets and materials to fulfill functional objectives and requirements while considering the limitations imposed by practicality, regulation, safety and cost. "Science is knowledge based on our observed facts and tested truths arranged in an orderly system that can be validated and communicated to other people. Engineering is the creative application of scientific principles used to plan, build, direct, guide, manage, or work on systems to maintain and improve our daily lives." The word ''engineer'' (Latin ) is derived from the Latin words ("to contrive, devise") and ("cleverness"). The foundational qualifications of an engineer typically include a four-year bachelor's degree in an engineering discipline, or in some jurisdictions, a master's degree in an engineering discipline plus four to six years of peer-reviewed professiona ...

Henry Roe Campbell
Henry Roe Campbell (September 9, 1807 – February 6, 1879) was an American surveyor and civil engineer. Campbell contributed to American railroading and bridge-building in the first half of the 19th century. Campbell patented his 4-4-0 design in February 1836, just a few months before the patent law was changed to require that claims include proof of originality or novelty. The 4-4-0 or American type steam locomotive was the most popular wheel arrangement in 19th century American railroads and was widely copied. White noted that the design was successful because it "... met every requirement of early United States railroads". At the end of Campbell's career. a Harper's Magazine article in March 1879 noted that the impact Campbell's design played in railroad development in the United States when it wrote: Not only did the new American Type steam locomotive deliver more horsepower, tractive effort, and reliability it also laid the groundwork for locomotive engineering in ...

Best Friend Of Charleston
The ''Best Friend of Charleston'' was a steam-powered railroad locomotive widely considered the first locomotive to be built entirely within the United States for revenue service. It produced the first locomotive boiler explosion in the United States. History The locomotive was built for the South Carolina Canal and Rail Road Company by the West Point Foundry of New York in 1830. Disassembled for shipment by boat to Charleston, South Carolina, it arrived in October of that year and was unofficially named ''The Best Friend of Charleston''. After its inaugural run on Christmas Day, it was used in regular passenger service along a demonstration route in Charleston. At the time, it was considered one of the fastest modes of transport, taking its passengers "on the wings of wind at the speed of ." The only faster mode of travel was by an experienced horse and rider. On June 17, 1831, the ''Best Friend'' was the first locomotive in the US to suffer a boiler explosion. The blast i ...

Steel
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lickey Incline
The Lickey Incline, south of Birmingham, is the steepest sustained main-line railway incline in Great Britain. The climb is a gradient of 1 in 37.7 (2.65% or 26.5‰ or 1.52°) for a continuous distance of two miles (3.2 km). Constructed originally for the Birmingham and Gloucester Railway (B&GR) and opened in 1840 it is located on the Cross Country Route between and stations in Worcestershire. In earlier times many trains required the assistance of banking locomotives with associated logistical considerations to ensure that the train reached the top; now only the heaviest of freight trains require such assistance. History and geography A survey by Isambard Kingdom Brunel in 1832 for a line between Birmingham and Gloucester followed a longer route well to the east with a maximum 1 in 300 gradient avoiding population centres, the plan lapsed with the cost being deemed too high. In 1836 William Moorsom was engaged on a ''no success - no fee'' to survey a suitable r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Birmingham And Bristol Railway
The Birmingham and Bristol Railway was a short-lived railway company, formed in 1845 by the merger of the Birmingham and Gloucester Railway and the Bristol and Gloucester Railway. Origin At Gloucester the latter had formed a junction with the broad gauge Cheltenham and Great Western Union Railway running into the town on mixed gauge tracks. In 1843 the C&GWU had been taken over by the Great Western Railway which began putting pressure on the Bristol and Gloucester to join the GWR at Bristol, to subscribe to the proposed South Devon Railway, and to convert to broad gauge track, to the alarm of the Northern "narrow" gauge railways. The "break-of-gauge" at Gloucester was a major problem. It caused pandemonium as whole trainloads of passengers, and their luggage, changed from one to another, together with the transshipment of goods. Formation Parliament had established a commission to examine the problem and there was a consensus that the track should be unified throughout the l ...

Tractive Effort
As used in mechanical engineering, the term tractive force can either refer to the total traction a vehicle exerts on a surface, or the amount of the total traction that is parallel to the direction of motion. In railway engineering, the term tractive effort is often used synonymously with tractive force to describe the pulling or pushing capability of a locomotive. In automotive engineering, the terms are distinctive: tractive effort is generally higher than tractive force by the amount of rolling resistance present, and both terms are higher than the amount of drawbar pull by the total resistance present (including air resistance and grade). The published tractive force value for any vehicle may be theoretical—that is, calculated from known or implied mechanical properties—or obtained via testing under controlled conditions. The discussion herein covers the term's usage in mechanical applications in which the final stage of the power transmission system is one ...

Cantilever
A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab. When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment. Cantilever construction allows overhanging structures without additional support. In bridges, towers, and buildings Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges, the cantilevers are usually built as pairs, with each cantilever used to support one end of a central section. The Forth Bridge in Scotland is an example of a cantilever truss bridge. A cantilever in a traditionally timber framed building is called a jetty or forebay. In the southe ...

England Loco Birmingham & Glos'ter Railway
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.
