Pennsylvania Railroad T1 Steam Locomotive Trust
Pennsylvania Railroad 5550 (PRR 5550) is a mainline Duplex locomotive, duplex drive steam locomotive under construction in the United States. With an estimated completion by 2030, the locomotive will become the 53rd example of the Pennsylvania Railroad's Pennsylvania Railroad class T1, T1 steam locomotive class and the only operational locomotive of its type. The estimated cost of PRR 5550 was originally $10 million, but an updated projected cost of $7 million was released with the acquisition of an existing long-haul tender from the Western New York Railway Historical Society in August 2017. Construction began in 2014 with the casting of the locomotive's Keystone (architecture), keystone-shaped number plate. Major components, including two Boxpok drivers, the prow, the cab, third-course boiler, and fire door have been completed. Introduction The original T1 Class The Pennsylvania Railroad class T1, Pennsylvania Railroad class T1 class steam locomotive was one of the most uniqu ...

4-4-4-4
A 4-4-4-4 steam locomotive, in the Whyte notation for describing locomotive wheel arrangements, has a four-wheel leading truck, two sets of four driving wheels, and a four-wheel trailing truck. While it would be possible to make an articulated locomotive of this arrangement, the only 4-4-4-4s ever built were duplex locomotives—with two sets of cylinders driving two sets of driven wheels in one rigid frame, essentially a 4-8-4 with divided drive. Usage The first locomotive built with this arrangement was the Baltimore and Ohio Railroad's sole class N-1 #5600 ''George H. Emerson'', constructed at the B&O's own Mount Clare Shops in May 1937. To reduce the fixed wheelbase, this locomotive had the two sets of cylinders at opposite ends, so that the rear pair were beside the firebox. This proved to be a poor design, as it restricted the firebox size and exposed the cylinders to dust and dirt, causing premature wear. The locomotive was not considered successful enough to duplica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel Slip
Slippery rail, or low railhead adhesion, is a condition of railways (railroads) where contamination of the railhead reduces the traction between the wheel and the rail. This can lead to wheelslip when the train is taking power, and wheelslide when the train is braking. One common cause of contamination is fallen leaves that adhere to the railhead (top surface) of railway tracks. The condition results in significant reduction in friction between train wheels and rails, and in extreme cases can render the track temporarily unusable. In Britain, the situation is colloquially referred to as "leaves on the line". Low adhesion caused by weather Railhead contamination caused by weather conditions can occur at any time of year. The leaf fall season causes the most disruption to rail operations. In heavily deciduous forested areas like the American Mid-Atlantic states, New England, many parts of Europe including the UK, and Southern Ontario, Canada, the problem can arise. Where the l ...

LNER Class P2
The London and North Eastern Railway Class P2 was a class of 2-8-2 steam locomotives designed by Sir Nigel Gresley for working heavy express trains over the harsh Edinburgh to Aberdeen Line. As they were to serve on Scottish expresses, they were given famous names from Scottish lore. Six locomotives of the class were built; introduced between 1934 and 1936. In 1936, the Class P2 were given streamlined fronts, similar to that of the Class A4. Between 1943 and 1944 the class were rebuilt under Gresley's successor Edward Thompson into the LNER Thompson Class A2/2 4-6-2 type. History Design The locomotives were designed by Nigel Gresley to haul express trains over the difficult Edinburgh to Aberdeen section of the London and North Eastern Railway. In the design Gresley was influenced by recent French practice, in particular passenger locomotives of the Paris à Orléans railway. The first locomotive of the class, No. 2001 ''Cock o' the North'', was introduced in 1934. It was b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

BR Standard Class 8
The BR Standard Class 8 was a class of a single 4-6-2 ''Pacific'' steam locomotive designed by Robert Riddles for use by British Railways. Only the prototype was constructed, named ''Duke of Gloucester''. Constructed at Crewe Works in 1954, the ''Duke'', as it is popularly known, was a replacement for the destroyed LMS Princess Royal Class locomotive number 46202 ''Princess Anne'', which was involved in the Harrow and Wealdstone rail crash of 1952. The ''Duke'' was based on the BR Standard Class 7 ''Britannia'' design. It incorporated three sets of modified Caprotti valve gear, relatively new to British locomotive engineering and more efficient than Walschaerts or Stephenson valve gear. The ''Duke'' was regarded as a failure by locomotive crews due to its poor steaming characteristics and its heavy fuel consumption. Trials undertaken by British Railways also returned negative feedback, reporting problems with the poor draughting of the locomotive which resulted in difficulty a ...

Chairman
The chairperson, also chairman, chairwoman or chair, is the presiding officer of an organized group such as a board, committee, or deliberative assembly. The person holding the office, who is typically elected or appointed by members of the group, presides over meetings of the group, and conducts the group's business in an orderly fashion. In some organizations, the chairperson is also known as ''president'' (or other title). In others, where a board appoints a president (or other title), the two terms are used for distinct positions. Also, the chairman term may be used in a neutral manner not directly implying the gender of the holder. Terminology Terms for the office and its holder include ''chair'', ''chairperson'', ''chairman'', ''chairwoman'', ''convenor'', ''facilitator'', '' moderator'', ''president'', and ''presiding officer''. The chairperson of a parliamentary chamber is often called the ''speaker''. ''Chair'' has been used to refer to a seat or office of authority ...

LNER Class A4 4468 Mallard
LNER Class A4 4468 ''Mallard'' is a 4-6-2 ("Pacific") steam locomotive built in 1938 for operation on the London and North Eastern Railway (LNER) at Doncaster Works to a design of Nigel Gresley. Its streamlined, wind tunnel tested design allowed it to haul long distance express passenger services at high speeds. On 3 July 1938, ''Mallard'' broke the world speed record for steam locomotives at , which still stands. While in British Railways days regular steam-hauled rail services in the UK were officially limited to a 90 mph 'line speed', before the war, the A4s had to run significantly above 90 mph just to keep schedule on trains such as the '' Silver Jubilee'' and '' The Coronation'', with the engines reaching 100 mph on many occasions. ''Mallard'' covered almost one and a half million miles (2.4 million km) before it was retired in 1963. The locomotive is long and weighs 165 long tons (168 tonnes, 369,600 lbs), including the tender. It is painted LNER garter ...

NYC Hudson
A New York Central Hudson was a popular 4-6-4 " Hudson" type steam locomotive built by the American Locomotive Company (ALCO) and the Lima Locomotive Works in three series from 1927 to 1938 for the New York Central Railroad. Named after the Hudson River, the 4-6-4 wheel arrangement came to be known as the "Hudson" type in the United States, as these locomotives were the first examples built and used in North America. Built for high-speed passenger train work, the Hudson locomotives were famously known for hauling the New York Central's crack passenger trains, such as the ''20th Century Limited'' and the ''Empire State Express''. With the onset of diesel locomotives by the mid-20th Century, all Hudson locomotives were retired and subsequently scrapped by 1957, with none preserved today except for a converted tender from J-1d 5313, which is preserved at the Steamtown National Historic Site in Scranton, Pennsylvania.

New York Central Railroad
The New York Central Railroad was a railroad primarily operating in the Great Lakes and Mid-Atlantic regions of the United States. The railroad primarily connected greater New York and Boston in the east with Chicago and St. Louis in the Midwest, along with the intermediate cities of Albany, Buffalo, Cleveland, Cincinnati, Detroit, Rochester and Syracuse. New York Central was headquartered in New York City's New York Central Building, adjacent to its largest station, Grand Central Terminal. The railroad was established in 1853, consolidating several existing railroad companies. In 1968, the NYC merged with its former rival, the Pennsylvania Railroad, to form Penn Central. Penn Central went bankrupt in 1970 and merged into Conrail in 1976. Conrail was broken-up in 1999, and portions of its system were transferred to CSX and Norfolk Southern Railway, with CSX acquiring most of the old New York Central trackage. Extensive trackage existed in the states of New York, Pennsyl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflation
In economics, inflation is an increase in the general price level of goods and services in an economy. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose. The employment cost index is also used for wages in the United States. Most economists agree that high levels of inflation as well as hyperinflation—which have severely disruptive effects on the real economy—are caused by persistent excessive growth in the money supply. Views on low to moderate rates of inflation are more varied. Low or moderate inflation may be attri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Excursion Train
An excursion train is a chartered train run for a special event or purpose. Examples are trains to major sporting event, trains run for railfans or tourists, and special trains operated by the railway company for employees and prominent customers. United Kingdom A number of excursion trains are run in the United Kingdom and in some cases there are regular steam worked passenger services over some routes, one such train being ''The Jacobite (steam train), The Jacobite'' which runs Monday to Friday from Fort William railway station, Fort William to Mallaig railway station, Mallaig from April to October. A second afternoon train also runs from May to mid September but on weekdays only, weekend services running from June to October. A number of Christmas Jacobite's have even started running on select days in December. There are also a number of routes across the UK which are famed for running excursion trains, examples include: Settle & Carlisle line, Cumbrian Coast line, North War ...

Diesel Locomotives
A diesel locomotive is a type of railway locomotive in which the prime mover is a diesel engine. Several types of diesel locomotives have been developed, differing mainly in the means by which mechanical power is conveyed to the driving wheels. Early internal combustion locomotives and railcars used kerosene and gasoline as their fuel. Rudolf Diesel patented his first compression-ignition engine in 1898, and steady improvements to the design of diesel engines reduced their physical size and improved their power-to-weight ratios to a point where one could be mounted in a locomotive. Internal combustion engines only operate efficiently within a limited power band, and while low power gasoline engines could be coupled to mechanical transmissions, the more powerful diesel engines required the development of new forms of transmission. This is because clutches would need to be very large at these power levels and would not fit in a standard -wide locomotive frame, or wear too quickl ...
