Hancock Air Whistle
The Hancock air whistle was a railroad whistle intended for use on North American diesel locomotives in place of the standard air horn. It was manufactured by the Hancock Valve Division of Manning, Maxwell and Moore. History Steam era Hancock was well known to the railroads during the days of steam. The company produced many appliances, one of which was the popular long-bell three-chime steam whistle. When railroads began dieselizing, Hancock, along with other manufacturers of railroad equipment, adjusted their offerings in order to remain competitive. And so Hancock modified their whistle design so they could be used on diesel locomotives. Diesel era Hancock already had vast experience with steam whistles, and practically none with air horns. Also, diesel locomotives were an emerging technology, and most early models were equipped with single-note 'honkers'. These horns were anything but appealing to the general public. Therefore, Hancock developed their line of air whist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

New York, New Haven And Hartford Railroad
The New York, New Haven and Hartford Railroad , commonly known as The Consolidated, or simply as the New Haven, was a railroad that operated principally in the New England region of the United States from 1872 to 1968. Founded by the merger of the New York and New Haven Railroad, New York and New Haven and Hartford and New Haven Railroad, Hartford and New Haven railroads, the company had near-total dominance of railroad traffic in Southern New England for the first half of the 20th century. Beginning in the 1890s and accelerating in 1903, New York banker J. P. Morgan sought to monopolize New England transportation by arranging the NH's acquisition of 50 companies, including other railroads and steamship lines, and building a network of electrified trolley lines that provided interurban transportation for all of southern New England. By 1912, the New Haven operated more than of track, with 120,000 employees, and practically monopolized traffic in a wide swath from Boston to New ...

Safety Equipment
Personal protective equipment (PPE) is protective clothing, helmets, goggles, or other garments or equipment designed to protect the wearer's body from injury or infection. The hazards addressed by protective equipment include physical, electrical, heat, chemical, biohazards, and airborne particulate matter. Protective equipment may be worn for job-related occupational safety and health purposes, as well as for sports and other recreational activities. ''Protective clothing'' is applied to traditional categories of clothing, and ''protective gear'' applies to items such as pads, guards, shields, or masks, and others. PPE suits can be similar in appearance to a cleanroom suit. The purpose of personal protective equipment is to reduce employee exposure to hazards when engineering controls and administrative controls are not feasible or effective to reduce these risks to acceptable levels. PPE is needed when there are hazards present. PPE has the serious limitation that it d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Railway Safety
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in tracks, which usually consist of two parallel steel rails. Rail transport is one of the two primary means of land transport, next to road transport. It is used for about 8% of passenger and freight transport globally, thanks to its energy efficiency and potentially high speed.Rolling stock on rails generally encounters lower frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by diesel or electric locomotives. While railway transport is capital-intensive and less flexible than road transport, it can carry heavy loads of passengers and cargo with greater energy efficiency and safety. Precursors of railways driven by human or animal power have existed since antiquity, but modern rail transport began with the invention of the steam locomotive in the United Kingdom at the beginning of the 19th c ...

Locomotive Parts
A locomotive is a rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, gravity or stationary engines that drove cable systems. Few such systems are sti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Whistle
A steam whistle is a device used to produce sound in the form of a whistle using live steam, which creates, projects, and amplifies its sound by acting as a vibrating system. Operation The whistle consists of the following main parts, as seen on the drawing: the whistle bell (1), the steam orifice or aperture (2), and the valve (9). When the lever (10) is actuated (usually via a pull cord), the valve opens and lets the steam escape through the orifice. The steam will alternately compress and rarefy in the bell, creating the sound. The pitch (music), pitch, or tone, is dependent on the length of the bell; and also how far the operator has opened the valve. Some locomotive engineers invented their own distinctive style of whistling. Uses of steam whistles Steam whistles are often used on buildings such as factory, factories, university, universities, and similar places to signal the start or end of a work shift, etc. Steam locomotive, Steam railway locomotives, traction e ...

EMD FL9
The EMD FL9 (New Haven Class EDER-5) is a model of electro-diesel locomotive, capable of operating either as a traditional diesel-electric locomotive or as an electric locomotive powered from a third rail ("dual power"). Sixty units were built between October 1956 and November 1960 by General Motors Electro-Motive Division for the New York, New Haven and Hartford Railroad (the "New Haven"). The locomotives were designed to allow diesel powered trains to enter Grand Central Terminal, where non-electric locomotives are forbidden. The FL9s continued in passenger service under the New Haven's successors, with the final units in revenue service retired by Metro-North Railroad in 2009. A number of FL9s have been preserved at museums or with private owners. Design Due to concerns about diesel emissions in the East River Tunnels and the underground tracks of Grand Central Terminal and Penn Station, passenger trains entering New York City have long been required to use electrical powe ...

Romanticism
Romanticism (also known as the Romantic movement or Romantic era) was an artistic and intellectual movement that originated in Europe towards the end of the 18th century. The purpose of the movement was to advocate for the importance of subjectivity and objectivity (philosophy), subjectivity, imagination, and appreciation of nature in society and culture in response to the Age of Enlightenment and the Industrial Revolution. Romanticists rejected the social conventions of the time in favour of a moral outlook known as individualism. They argued that passion (emotion), passion and intuition were crucial to understanding the world, and that beauty is more than merely an classicism, affair of form, but rather something that evokes a strong emotional response. With this philosophical foundation, the Romanticists elevated several key themes to which they were deeply committed: a Reverence (emotion), reverence for nature and the supernatural, nostalgia, an idealization of the past as ...

Train Whistle
A train whistle or air whistle (originally referred to as a train trumpet or air trumpet) is an audible signaling device on a steam or gas locomotive, used to warn that the train is approaching, and to communicate with rail workers. Modern diesel and electric locomotives primarily use a powerful air horn instead of a whistle as an audible warning device. However, the word ''whistle'' continues to be used by railroaders in referring to such signaling practices as "whistling off" (sounding the horn when a train gets underway). The need for a whistle on a locomotive exists because trains move on fixed rails and thus are uniquely susceptible to collision. This susceptibility is exacerbated by a train's enormous weight and inertia, which make it difficult to quickly stop when encountering an obstacle. Hence a means of warning others of the approach of a train from a distance is necessary. As train whistles are inexpensive compared to other warning devices, the use of loud and dis ...

Dieselisation
Dieselisation (US: dieselization) is the process of equipping vehicles with a diesel engine or diesel engines. It can involve replacing an internal combustion engine powered by petrol (US: gasoline) fuel with an engine powered by diesel fuel, as occurred on a large scale with trucks, buses, farm tractors, trains, and building construction machinery after World War II. Alternatively it can involve replacing the entire plant or vehicle with one that is diesel-powered; the term commonly describes the generational replacement between the 1930s to 1970s of railway steam locomotives with diesel locomotives, and associated facilities. Water transport The two-stroke diesel engine for marine applications was introduced in 1908 and remains in use today. It is the most efficient prime mover to date, models such as the Wärtsilä-Sulzer RTA96-C offer a thermal efficiency of 50% and over 100,000 horsepower. First steps towards conversions using diesel engines as means of propulsion (on sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
