Dynamometer Car
A dynamometer car is a railroad maintenance of way car used for measuring various aspects of a locomotive's performance. Measurements include tractive effort (pulling force), power, top speed, etc. History The first dynamometer car was probably one built in about 1838 by the "Father of Computing" Charles Babbage. Working for the Great Western Railway of Great Britain, he equipped a passenger carriage to be placed between an engine and train and record data on a continuously moving roll of paper. The recorded data included the pulling force of the engine, a plot of the path of the carriage and the vertical shake of the carriage. The work was undertaken to help support the position of the Great Western Railway in the controversy over standardizing the British track gauge. In the United States, the Pennsylvania Railroad began using dynamometer cars in the 1860s. The first modern dynamometer car in the United States was built in 1874 by P. H. Dudley for the New York Central Rai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
North Eastern Railway Dynamometer Car National Railway Museum York Object Number 1975-7050
North is one of the four compass points or cardinal directions. It is the opposite of south and is perpendicular to east and west. ''North'' is a noun, adjective, or adverb indicating direction or geography. Etymology The word ''north'' is related to the Old High German ''nord'', both descending from the Proto-Indo-European unit *''ner-'', meaning "left; below" as north is to left when facing the rising sun. Similarly, the other cardinal directions are also related to the sun's position. The Latin word ''borealis'' comes from the Greek ''boreas'' "north wind, north" which, according to Ovid, was personified as the wind-god Boreas, the father of Calais and Zetes. ''Septentrionalis'' is from ''septentriones'', "the seven plow oxen", a name of ''Ursa Major''. The Greek ἀρκτικός (''arktikós'') is named for the same constellation, and is the source of the English word ''Arctic''. Other languages have other derivations. For example, in Lezgian, ''kefer'' can mean b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
National Railway Museum
The National Railway Museum (NRM) is a museum in York, England, forming part of the Science Museum Group. The museum tells the story of rail transport in Britain and its impact on society.

Maintenance Of Way Equipment
Railway track ( and UIC terminology) or railroad track (), also known as permanent way () or "P way" ( and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade. It enables trains to move by providing a dependable, low-friction surface on which steel wheels can roll. Early tracks were constructed with wooden or cast-iron rails, and wooden or stone sleepers. Since the 1870s, rails have almost universally been made from steel. Historical development The first railway in Britain was the Wollaton wagonway, built in 1603 between Wollaton and Strelley in Nottinghamshire. It used wooden rails and was the first of about 50 wooden-railed tramways built over the subsequent 164 years. These early wooden tramways typically used rails of oak or beech, attached to wooden sleepers with iron or wooden nails. Gravel or small stones were packed ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the imperial horsepower as in "hp" or "bhp" which is about , and the metric horsepower as in "cv" or "PS" which is approximately . The electric horsepower "hpE" is exactly , while the boiler horsepower is 9809.5 or 9811 watts, depending on the exact year. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other power-generating machinery such as piston engines, turbines, and electric motors. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 201 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Integrator
An integrator in measurement and control applications is an element whose output signal is the time integral of its input signal. It accumulates the input quantity over a defined time to produce a representative output. Integration is an important part of many engineering and science, scientific applications. Mechanical integrators are the oldest type and are still used for metering water flow or electrical power. Electronic analogue integrators, which have generally displaced mechanical integrators, are the basis of analog computers and charge amplifiers. Integration can also be performed by algorithms in digital computers. Mechanical integrators One simple kind of mechanical integrator is the disk-and-wheel integrator. This functions by placing a wheel on and perpendicular to a spinning disk, held there by means of a freely spinning shaft parallel to the disk. Because the speed at which a part of the disk turns is proportional to its distance from the center, the rate at whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Illinois Railway Museum
The Illinois Railway Museum (IRM, reporting mark IRMX) is the largest railroad museum in the United States. It is located in the Chicago metropolitan area at 7000 Olson Road in Union, Illinois, northwest of downtown Chicago. Overview History The museum was founded in 1953 by ten people who joined to purchase Indiana Railroad interurban car 65. Originally called the Illinois Electric Railway Museum, the museum was located on the grounds of the Chicago Hardware Foundry in North Chicago. In 1961, it was renamed to the Illinois Railway Museum to reflect its expanding scope. In 1964, the museum moved to Union, Illinois along the former right-of-way of the Elgin and Belvidere Electric Company. In 1968 the first steam locomotive was operated at the museum. The first storage barn was erected in 1972. In 1981, a streetcar loop was constructed. The right-of-way the museum was constructed next to still had back taxes into the 1980s. To gain full use of the track, the museum p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chicago, Burlington And Quincy Railroad
The Chicago, Burlington and Quincy Railroad was a railroad that operated in the Midwest, Midwestern United States. Commonly referred to as the Burlington Route, the Burlington, CB&Q, or as the Q, it operated extensive trackage in the states of Colorado, Illinois, Iowa, Missouri, Nebraska, Wisconsin, Wyoming, and also in Texas through subsidiaries Colorado and Southern Railway, Fort Worth and Denver Railway, and Burlington-Rock Island Railroad. Its primary connections included Chicago, Minneapolis–Saint Paul, St. Louis, Kansas City, Missouri, Kansas City, and Denver. Because of this extensive trackage in the midwest and mountain states, the railroad used the advertising slogans "Everywhere West", "Way of the ''Zephyrs''", and "The Way West".

1948 Locomotive Exchange Trials
The 1948 Locomotive Exchange Trials were organised by the newly nationalised British Railways (BR). Locomotives from the former "Big Four" constituent companies ( GWR, LMS, LNER, SR) were transferred to and worked on other regions. Officially, these comparisons were to identify the best qualities of the four different schools of thought of locomotive design so that they could be used in the planned BR standard designs. However, the testing had little scientific rigour, and political influence meant that LMS practice was largely followed by the new standard designs regardless. However, the trials were useful publicity for BR to show the unity of the new British Railways. To record the locomotive performances, one of three dynamometer cars were included in the train directly behind the locomotive (with a GWR, LMS and NER version being available). LMS engines which operated over the Southern Region, where there were no water troughs, were paired with four-axled ex-WD tender ...
