Caboose
A caboose is a crewed North American railroad car coupled at the end of a freight train. Cabooses provide shelter for crew at the end of a train, who were formerly required in switching and shunting; as well as in keeping a lookout for load shifting, damage to equipment and cargo, and overheating axles. Originally flatcars fitted with cabins or modified box cars, they later became purpose-built, with bay windows above or to the sides of the car to allow crew to observe the train. The caboose also served as the conductor's office, and on long routes, included sleeping accommodations and cooking facilities. A similar railroad car, the brake van, was used on British and Commonwealth railways outside North America (the role has since been replaced by the crew car in Australia). On trains not fitted with continuous brakes, brake vans provided a supplementary braking system, and they helped keep chain couplings taut. Cabooses were used on every freight train in the United ...

End-of-train Device
The end of train device (ETD), sometimes referred to as an EOT, flashing rear-end device (FRED) or sense and braking unit (SBU) is an electronic device mounted on the end of freight trains in replacement of a caboose. They are divided into three categories: "dumb" units, which only provide a visible indication of the rear of the train with a flashing red taillight; "average intelligence" units with a brake pipe pressure gauge; and "smart" units, which send back data to the crew in the locomotive via radio-based telemetry. They originated in North America, and are also used elsewhere in the world, where they may include complete End of Train Air System (ETAS) or Sense and Brake Unit (SBU) devices. Tail lamps The earliest known method of showing the position of and completeness of a train was by the Stockton and Darlington Railway in the 1830s. These early references are to the use of a burning brazier on the rear of the locomotive. It is easy to imagine that the danger represe ...

Railroad Car
A railroad car, railcar (American English, American and Canadian English), railway wagon, railway carriage, railway truck, railwagon, railcarriage or railtruck (British English and International Union of Railways, UIC), also called a train car, train wagon, train carriage or train truck, is a vehicle used for the carrying of cargo or passengers on a rail transport network (a railroad/railway). Such cars, when coupled together and hauled by one or more locomotives, form a train. Alternatively, some Passenger railroad car, passenger cars are self-propelled in which case they may be either single railcars or make up multiple units. The term "car" is commonly used by itself in American English when a rail context is implicit. Indian English sometimes uses "bogie" in the same manner, though the term has Bogie, other meanings in other variants of English. In American English, "railcar" is a generic term for a railway vehicle; in other countries "railcar" refers specifically to ...

Conductor (transportation)
A conductor (North American English) or guard (Commonwealth English) is a train crew member responsible for operational and safety duties that do not involve actual operation of the train/locomotive. The role is common worldwide under various job titles, although on many railroads the role has been discontinued. The ''conductor'' title is most common in North America. In Commonwealth countries, the conductor (also sometimes known as ''train manager'') is someone who sells and/or inspects tickets. The responsibilities of the role typically include the following: * ensuring that the train follows applicable safety rules and practices * making sure that the train stays on schedule starting from the stations * opening and closing power operated doors * selling and checking tickets, and other customer service duties * ensuring that any cars and cargo are picked up and dropped off properly * completing en-route paperwork * directing the train's movement while operating in reverse * ...

Brake Van
Brake van and guard's van are terms used mainly in the UK, Ireland, Australia and India for a Rolling stock, railway vehicle equipped with a hand brake which can be applied by the Conductor (transportation), guard. The equivalent North American term is caboose, but a British brake van and a caboose are very different in appearance, and use because the former usually has only four wheels, while the latter usually has bogies, as well as American Cabooses not being used to provide braking on a train, and instead serving as a mobile office for the Conductor_(rail), conductor and the Brakeman, brakemen who helped monitor the train. German railways employed brakeman's cabins combine car, combined into other cars. Many British freight trains formerly had no continuous brake so the only available brakes were those on the locomotive and the brake van. Because of this shortage of brake power, the speed was restricted to . The brake van was marshalled at the rear of the train so both por ...

Defect Detectors
A defect detector is a device used on railroads to detect axle and signal problems in passing trains. The detectors are normally integrated into the tracks and often include sensors to detect several different kinds of problems that could occur. Defect detectors were one of the inventions which enabled American railroads to eliminate the caboose at the rear of the train, as well as various station agents placed along active routes to detect unsafe conditions. The use of defect detectors has since spread overseas to other railroad systems. History Before the advent of automated detectors, on-board train crew and track-side workers used to visually inspect trains for defects, like " hotboxes" (overheating bearings) which would smoke or glow red. By the 1940s, automatic defect detectors included infrared sensors for hotboxes, wires outlining the clearance envelope to detect high and wide loads, and "brittle bars" – frangible bars mounted between the rails – to detect draggin ...

Brakeman's Cabin
A brakeman's cabin (also brakeman's cab) or brakeman's caboose (US) (German: Bremserhaus) was a small one-man compartment at one end of a railway wagon to provide shelter for the brakeman from the weather and in which equipment for manually operating the wagon brake was located. They were built in the days before railway air brake, continuous braking was available and the locomotive brake needed to be augmented by brakemen applying the wagon brakes individually. History In the early years of the railway, brakemen just had an open seat. The first cabs appeared around 1880. The number of brakeman's cabs occupied in a given train depended on the conditions of the route and the speed of the train; on some trains all the cabs might be occupied. Communication between engine driver and brakemen was by train whistle signals which required the design of the brakeman's cab to be partially open to the elements. Risk Working in brakeman's cabins was dangerous, especially in winter because th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Middle Dutch
Middle Dutch is a collective name for a number of closely related West Germanic dialects whose ancestor was Old Dutch. It was spoken and written between 1150 and 1500. Until the advent of Modern Dutch after 1500 or , there was no overarching standard language, but all dialects were mutually intelligible. During that period, a rich Medieval Dutch literature developed, which had not yet existed during Old Dutch. The various literary works of the time are often very readable for speakers of Modern Dutch since Dutch is a rather conservative language. Phonology Differences with Old Dutch Several phonological changes occurred leading up to the Middle Dutch period. * Earlier Old Dutch , , merge into already in Old Dutch. * Voiceless fricatives become voiced syllable-initially: > , > (merging with from Proto-Germanic ), > . (10th or 11th century) * > * > or . The outcome is dialect-specific, with found in more western dialects and further east. This results in later pairs ...

Middle Low German
Middle Low German is a developmental stage of Low German. It developed from the Old Saxon language in the Middle Ages and has been documented in writing since about 1225–34 (). During the Hanseatic period (from about 1300 to about 1600), Middle Low German was the leading written language in the north of Central Europe and served as a lingua franca in the northern half of Europe. It was used parallel to medieval Latin also for purposes of diplomacy and for deeds. Terminology While ''Middle Low German'' (MLG) is a scholarly term developed in hindsight, speakers in their time referred to the language mainly as (Saxon) or (the Saxon language). In contrast to Latin as the primary written language, speakers also referred to discourse in Saxon as speaking/writing , i.e. 'clearly, intelligibly'. This contains the same root as 'German' (cf., High German: , Dutch ( archaically ''N(i)ederduytsche'' to mean the contemporary version of the Dutch language) both from Proto-Germanic ...

Roller Bearing
In mechanical engineering, a rolling-element bearing, also known as a rolling bearing,ISO 15 is a bearing which carries a load by placing rolling elements (such as balls, cylinders, or cones) 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 is a set 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 onto 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 spheres or cylinders called "rollers" tig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Southern Pacific Railroad
The Southern Pacific (or Espee from the railroad initials) was an American Railroad classes#Class I, Class I Rail transport, railroad network that existed from 1865 to 1996 and operated largely in the Western United States. The system was operated by various companies under the names Southern Pacific Railroad, Southern Pacific Company and Southern Pacific Transportation Company. The original Southern Pacific began in 1865 as a land holding company. The last incarnation of the Southern Pacific, the Southern Pacific Transportation Company, was founded in 1969 and assumed control of the Southern Pacific system. The Southern Pacific Transportation Company was acquired in 1996 by the Union Pacific Corporation and merged with their Union Pacific Railroad. The Southern Pacific legacy founded hospitals in San Francisco, Tucson, Arizona, Tucson, and Houston. In the 1970s, it also founded a telecommunications network with a state-of-the-art microwave and fiber optic backbone. This telec ...
