Pennsylvania Railroad K4 Class
The Pennsylvania Railroad (PRR) K4 4-6-2 "Pacific" (425 built 1914–1928, PRR Altoona, Baldwin) was its premier passenger-hauling steam locomotive from 1914 through the end of steam on the PRR in 1957. Attempts were made to replace the K4s, including the K5 and the T1 duplex locomotive, but neither was very successful. The K4s hauled the vast majority of express passenger trains until they were replaced by diesel locomotives. The K4s were not powerful enough for the heavier trains they often pulled from the mid-1930s onward, so they were often double- or even triple-headed, sometimes with atlantic class locomotives. This was effective, but expensive, and several crews were needed. The PRR did have the extra locomotives, many having been displaced by electrification east of Harrisburg. The two preserved K4s Nos. 1361 and 3750 were designated as Pennsylvania's official state steam locomotives on December 18, 1987, when Pennsylvania Governor Robert P. Casey signed into la ...

Railway Electrification System
A railway electrification system supplies electric power to railway trains and trams without an on-board prime mover or local fuel supply. Electric railways use either electric locomotives (hauling passengers or freight in separate cars), electric multiple units (passenger cars with their own motors) or both. Electricity is typically generated in large and relatively efficient generating stations, transmitted to the railway network and distributed to the trains. Some electric railways have their own dedicated generating stations and transmission lines, but most purchase power from an electric utility. The railway usually provides its own distribution lines, switches, and transformers. Power is supplied to moving trains with a (nearly) continuous conductor running along the track that usually takes one of two forms: an overhead line, suspended from poles or towers along the track or from structure or tunnel ceilings, or a third rail mounted at track level and contacted by a s ...

Reversing Gear
On a steam locomotive, the reversing gear is used to control the direction of travel of the locomotive. It also adjusts the cutoff of the steam locomotive. Reversing lever This is the most common form of reverser. It consists of a long lever mounted, parallel to the direction of travel, on the driver’s side of the cab. It has a handle and sprung trigger at the top and is pivoted at the bottom so as to pass between two notched sector plates. The reversing rod, which connects to the valve gear, is attached to this lever, either above or below the pivot, in such a position as to give good leverage. A square pin is arranged so as to engage with the notches in the plates and hold the lever in the desired position when the trigger is released. The advantages of this design are that change between forward and reverse gear can be made very quickly as is needed in, for example, a shunting engine. Disadvantages are that, because the lever must rest at one of the notches, fine adjustment ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Grate Area
Grate firing is a type of industrial combustion system used for solid fuels. It now is used mainly for burning waste and biomass, but also for smaller coal furnaces. * Capacities 0.3 to 175 MWth in industry and CHP * Fuel fired per grate area 1-2 MW/m2, maximum grate area 100 m2 * Grates are typical only suitable for coarse particles, for fine particles a spreader is required, increases max. capacity * Primary air through the grate (also used for cooling) and secondary air Types ;Travelling grate :A moving grate which is covered with a fuel layer, 10-30 cm. Power control by means of varying the grate velocity ;Reciprocating grate :For ash-rich, low calorific fuels like municipal waste, arrangement of stationary and moving grates -> conveying and mixing (forward-moving type or reverse-action grate) ;Vibrating grate :Water cooled membrane wall, with holes for air. For burning coal or wood. Grate area The grate area is the area of the grate (length x width). The larger the grate ...

Trailing Truck
On a steam locomotive, a trailing wheel or trailing axle is generally an unpowered wheel or axle ( wheelset) located behind the driving wheels. The axle of the trailing wheels is usually located in a trailing truck. On some large locomotives, a booster engine was mounted on the trailing truck to provide extra tractive effort when starting a heavy train and at low speeds on gradients. Trailing wheels were used in some early locomotives but fell out of favor for a time during the latter 19th century. As demand for more powerful locomotives increased, trailing wheels began to be used to support the crew cab and rear firebox area. Trailing wheels first appeared on American locomotives between 1890 and 1895, but their axle worked in rigid pedestals. It enabled boilers to be lowered, since the top of the main frames was dropped down behind the driving wheels and under the firebox. The firebox could also be longer and wider, increasing the heating surface area and steam generation c ...

4-4-2 (locomotive)
Under the Whyte notation for the classification of steam locomotives by wheel arrangement, represents a configuration of a four-wheeled leading bogie, four powered and coupled driving wheels, and two trailing wheels supporting part of the weight of the boiler and firebox. This allows a larger firebox and boiler than the configuration. This wheel arrangement is commonly known as the Atlantic type, although it is also sometimes called a Milwaukee or 4-4-2 Milwaukee, after the Milwaukee Road, which employed it in high speed passenger service. Overview While the wheel arrangement and type name Atlantic would come to fame in the fast passenger service competition between railroads in the United States by mid-1895, the tank locomotive version of the Atlantic type first made its appearance in the United Kingdom in 1880, when William Adams designed the 1 Class T of the London, Tilbury and Southend Railway (LT&SR).

PRR E6
Class E6 on the Pennsylvania Railroad was the final type of 4-4-2 "Atlantic" locomotive built by the railroad, and second only to the Milwaukee Road's streamlined class A in size, speed and power. Although quickly ceding top-flight trains to the larger K4s Pacifics, the E6 remained a popular locomotive on lesser services and some lasted to the end of steam on the PRR. One, #460, called the Lindbergh Engine, is preserved at the Railroad Museum of Pennsylvania. It was moved indoors to begin preparations for restoration on March 17, 2010. On January 10, 2011, PRR #460 was moved to the museum's restoration shop for a two- to three-year project, estimated to cost $350,000. The engine is listed in the National Register of Historic Places. "New life for old iron," January 11, 2011, Intelligencer Journal/New Era, Lancaster, PA Design The E6 was designed by the Pennsy's General Superintendent of Motive Power, Lines East, Alfred W. Gibbs, and his team. They produced an Atlantic o ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

American Locomotive Company
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer of locomotives, diesel generators, steel, and tanks that operated from 1901 to 1969. The company was formed by the merger of seven smaller locomotive manufacturers and Schenectady Locomotive Works, Schenectady Locomotive Engine Manufactory of Schenectady, New York. A subsidiary, American Locomotive Automobile Company, designed and manufactured automobiles under the Alco brand from 1905 to 1913. ALCO also produced nuclear reactors from 1954 to 1962. The company changed its name to Alco Products, Incorporated in 1955. In 1964, the Worthington Corporation acquired the company. The company went out of business in 1969. The ALCO name is currently being used by Fairbanks-Morse, Fairbanks Morse Engine for their FM, ALCO line. Foundation and early history The company was created in 1901 from the merger of seven smaller locomotive manufacturers with Schenectady Locomotive Works, Schenect ...

PRR K29s
The Pennsylvania Railroad's class ''K29s'' comprised a single experimental 4-6-2 "Pacific" type steam locomotive. Constructed by Alco-Schenectady, it was given road number 3395. Although only one demonstrator was constructed, the K29s would become the basis for the highly successful K4s Pacifics and L1s Mikados. The lone example spent most of its life on the PRR's Pittsburgh division main line and was retired around 1929. History The sole K29s, PRR 3395, was constructed by the American Locomotive Company's Schenectady works in 1911 as a demonstrator engine for the Pennsylvania Railroad. The success of the single experimental K29s lead to the development of the equally successful K4s class Pacific and L1s class Mikado locomotives. Despite its success, the K29s was one of only a handful of locomotives constructed by Alco Schenectady as the PRR preferred its own Altoona Works as well the Baldwin Locomotive Works in Philadelphia for large scale locomotive production. The sole K29s ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

2-8-2
Under the Whyte notation for the classification of steam locomotives, represents the wheel arrangement of two leading wheels on one axle, usually in a leading truck, eight powered and coupled driving wheels on four axles and two trailing wheels on one axle, usually in a trailing truck. This configuration of steam locomotive is most often referred to as a Mikado, frequently shortened to Mike. At times it was also referred to on some railroads in the United States of America as the McAdoo Mikado and, during World War II, the MacArthur. The notation 2-8-2T indicates a tank locomotive of this wheel arrangement, the "T" suffix indicating a locomotive on which the water is carried in tanks mounted on the engine rather than in an attached tender. Overview The 2-8-2 wheel arrangement allowed the locomotive's firebox to be placed behind instead of above the driving wheels, thereby allowing a larger firebox that could be both wide and deep. This supported a greater rate of combustion ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

PRR L1s
Class L1s on the Pennsylvania Railroad comprised 574 2-8-2 "Mikado" type steam locomotives constructed between 1914 and 1919 by the railroad's own Juniata Shops (344 examples) as well as the Baldwin Locomotive Works (205) and the Lima Locomotive Works (25). It was the largest class of 2-8-2 locomotives anywhere, although other railroads had more Mikados in total. The L1s shared the boiler and many other components with the K4s 4-6-2 "Pacific" type, giving a total of 425 locomotives with many standard parts. Although the L1s type was quite successful, it was very much eclipsed in PRR service by the larger and more powerful I1s/I1sa 2-10-0 "Decapods", which arrived in service only two years after the L1s and were very suited to the PRR's mountain grades and heavy coal and mineral trains, and by the 1923 introduction of the M1 4-8-2 "Mountains" which took on the best high-speed freight runs. Large numbers of the class were stored out of service during the Great Depression, only to ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Axel Vogt
Axel S. Vogt (January 19, 1849 – November 11, 1921) was the Pennsylvania Railroad's Chief Mechanical Engineer between March 1, 1887, and February 1, 1919. He was succeeded by William Frederic Kiesel, Jr. After retiring from the PRR, Vogt continued to consult for the Baldwin Locomotive Works until his death. Among his accomplishments was the creation of the world's first static locomotive test facility at the Pennsylvania Railroad's Altoona Works, enabling locomotives to be exhaustively and repeatably tested under load – essentially, a locomotive version of the chassis dynamometer. Under his supervision, the PRR designed and produced many noteworthy steam locomotive designs, such as the E6 Atlantics, K4s The Pennsylvania Railroad (PRR) K4 4-6-2 "Pacific" (425 built 1914–1928, PRR Altoona, Baldwin) was its premier passenger-hauling steam locomotive from 1914 through the end of steam on the PRR in 1957.
