H. K. Porter, Inc
H.K. Porter, Inc. (Porter) manufactured light-duty railroad locomotives in the US, starting in 1866. The company became the largest producer of industrial locomotives, and built almost eight thousand of them. The last locomotive was built in 1950, but the company continues to produce industrial equipment to this day. Porter was known for building locomotives for industrial railways, which were often small enough that they could be operated by one person. Porter built mostly steam locomotives, but also some gas- and diesel- engined locomotives, and some that ran on compressed air. History In 1866 Henry Kirke Porter formed a partnership with John Y. Smith, forming the company Smith & Porter. They opened a small machine shop on 28th Street in Pittsburgh, Pennsylvania, and begin repairing and building industrial equipment. They received an order for their first locomotive on March 4, 1867, and built the ''Joshua Rhodes'' for the New Castle Railroad and Mining Company. They wen ...

Railroad
Rail transport (also known as train transport) is a means of transport using wheeled vehicles running in railway track, tracks, which usually consist of two parallel steel railway track, 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 rail freight transport, freight transport globally, thanks to its Energy efficiency in transport, energy efficiency and potentially high-speed rail, high speed.Rolling stock on rails generally encounters lower friction, frictional resistance than rubber-tyred road vehicles, allowing rail cars to be coupled into longer trains. Power is usually provided by Diesel locomotive, diesel or Electric locomotive, electric locomotives. While railway transport is capital intensity, 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 an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressed-air Locomotive
A fireless locomotive is a type of locomotive which uses reciprocating engines powered from a reservoir of compressed air or steam, which is filled at intervals from an external source. They offer advantages over conventional steam locomotives of lower cost per unit, cleanliness, and decreased risk from fire or boiler explosion; these are counterbalanced by the need for a source to refill the locomotive, and by the limited range afforded by the reservoir. They were desirable in situations where smoke from a firebox would be too noxious, or where there was risk of fire or explosion. Typical usage was in a mine, or a food or chemical factory. They were also used where a source of air or steam was readily available, and for moving loads within limited areas, such as a switch yard or within an industrial factory. They were eventually replaced for most uses by diesel and battery electric locomotives fitted with protective appliances; these are described as flame-proof locomotives. ...

Rocket Motor
A rocket engine is a reaction engine, producing thrust in accordance with Newton's third law by ejecting reaction mass rearward, usually a high-speed jet of high-temperature gas produced by the combustion of rocket propellants stored inside the rocket. However, non-combusting forms such as cold gas thrusters and nuclear thermal rockets also exist. Rocket vehicles carry their own oxidiser, unlike most combustion engines, so rocket engines can be used in a vacuum, and they can achieve great speed, beyond escape velocity. Vehicles commonly propelled by rocket engines include missiles, artillery shells, ballistic missiles and rockets of any size, from tiny fireworks to man-sized weapons to huge spaceships. Compared to other types of jet engine, rocket engines are the lightest and have the highest thrust, but are the least propellant-efficient (they have the lowest specific impulse). The ideal exhaust is hydrogen, the lightest of all elements, but chemical rockets produce a mix o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Davenport Locomotive Works
The Davenport Locomotive Works, of Davenport, Iowa, United States, USA, was formed as the W W Whitehead Company in 1901. In 1902, the company commenced building light locomotives. The Company was renamed the Davenport Locomotive Works in 1904. In late 1930, Davenport was licensed to assemble and market R. G. LeTourneau, R G LeTourneau Inc products under the Davenport-LeTourneau brand. The agreement is believed to have ended in 1935 when LeTourneau moved to Peoria, Illinois. Davenport also sold Davenport-Winchell three-wheel roller conversions of industrial wheel tractors, Davenport-Frink snow plows, which were built in license from Frink Sno-Plows Inc, and Reynolds patented Mov-Mor rotary scrapers. In 1933, the company was again restructured and renamed the Davenport-Besler Corporation, which continued in business until 1956. William George Besler was a director at the time of the restructuring. The company acquired the locomotive business of H. K. Porter, Inc. in 1950 and from ...

Bankruptcy
Bankruptcy is a legal process through which people or other entities who cannot repay debts to creditors may seek relief from some or all of their debts. In most jurisdictions, bankruptcy is imposed by a court order, often initiated by the debtor. Bankrupt is not the only legal status that an insolvent person may have, meaning the term ''bankruptcy'' is not a synonym for insolvency. Etymology The word ''bankruptcy'' is derived from Italian language, Italian , literally meaning . The term is often described as having originated in Renaissance Italy, where there allegedly existed the tradition of smashing a banker's bench if he defaulted on payment. However, the existence of such a ritual is doubted. History In Ancient Greece, bankruptcy did not exist. If a man owed and he could not pay, he and his wife, children or servants were forced into "debt slavery" until the creditor recouped losses through their Manual labour, physical labour. Many city-states in ancient Greece lim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baldwin Locomotive Works
The Baldwin Locomotive Works (BLW) was an American manufacturer of railway locomotives from 1825 to 1951. Originally located in Philadelphia, Pennsylvania, it moved to nearby Eddystone, Pennsylvania, Eddystone in the early 20th century. The company was for decades the world's largest producer of steam locomotives, but struggled to compete when demand switched to diesel locomotives. Baldwin produced the last of its 70,000-plus locomotives in 1951, before merging with the Lima Locomotive Works, Lima-Hamilton Corporation on September 11, 1951, to form the Baldwin-Lima-Hamilton Corporation. The company has no relation to the E.M. Baldwin and Sons of New South Wales, Australia, a builder of small diesel locomotives for sugar cane railroads. History: 19th century Beginning Matthias W.

Tank Locomotives
A tank locomotive is a steam locomotive which carries its water in one or more on-board water tanks, instead of a more traditional tender (rail), tender. Most tank engines also have Fuel bunker, bunkers (or fuel tanks) to hold fuel; in a #Tender-tank, tender-tank locomotive a tender holds some or all of the fuel, and may hold some water also. There are several different types of tank locomotive, distinguished by the position and style of the water tanks and fuel bunkers. The most common type has tanks mounted either side of the boiler. This type originated about 1840 and quickly became popular for industrial tasks, and later for Shunting (rail), shunting and shorter-distance Main line (railway), main line duties. Tank locomotives have #Advantages and disadvantages, advantages and disadvantages compared to traditional locomotives that required a separate tender to carry needed water and fuel.
