PRR E7
The Pennsylvania Railroad's class E2, E3, E7 steam locomotives were of the "Atlantic" passenger type, frequently called light Atlantics after the introduction of the heavier E6 Atlantics. All were similar in size and boiler capacity but differed in firebox type, valves and valve gear and cylinder diameter. Classes E2 and E3 were built simultaneously. Starting in 1916 a rebuilding program converted ninety class E2a, b, and c to class E7s by replacing slide valves with piston valves and increasing cylinder diameter from . Fourteen class E2 were similarly converted to class E7sa. Ninety class E2a,d, E3a,d were converted to class E3sd. These improvements allowed many of the engines to remain in active service into the 1930s. The sub-classes differed as follows: In the first decade of the twentieth century classes E2 and E3 handled all of the fast passenger trains of the Pennsylvania Railroad. As train weights increased due to the switch to steel passenger cars and more cars per t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRR 7002
Pennsylvania Railroad 7002 is a preserved E7 class "Atlantic" type steam locomotive built for the Pennsylvania Railroad by their own Altoona Works in August 1902. Today, it is on display at the Railroad Museum of Pennsylvania outside of Strasburg, Pennsylvania. Originally No. 8063, the PRR renumbered it to No. 7002 after the original, claimed to be a land-speed-record-setter, was scrapped. It is the only survivor of its class and was listed on the National Register of Historic Places on December 17, 1979. History Revenue service The E7s-class was created by replacing the slide valves above the cylinders on the E2a, E2b and E2c-classes with piston valves. Unlike the E2, the E2a, b, c and subsequent E7s class used Belpaire firebox instead of a "radial stay" firebox. The original No. 7002 was an E2-class locomotive built in August 1902 by the Pennsylvania Railroad's Altoona Works in Altoona, Pennsylvania. On June 15, the PRR inaugurated its new 18-hour train service from New York ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Steam Locomotives Of The United States
Steam is water vapor, often mixed with air or an aerosol of liquid water droplets. This may occur due to evaporation or due to boiling, where heat is applied until water reaches the enthalpy of vaporization. Saturated or superheated steam is invisible; however, wet steam, a visible mist or aerosol of water droplets, is often referred to as "steam". When liquid water becomes steam, it increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the Industrial Revolution and modern steam turbines are used to generate more than 80% of the world's electricity. If liquid water comes in contact with a very hot surface or depressurizes quickly below its vapour pressure, it can create a steam explosion. Types of steam and conversions Steam is trad ...

Railway Locomotives Introduced In 1916
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 19 ...

Pennsylvania Railroad Locomotives
Pennsylvania, officially the Commonwealth of Pennsylvania, is a U.S. state, state spanning the Mid-Atlantic (United States), Mid-Atlantic, Northeastern United States, Northeastern, Appalachian, and Great Lakes region, Great Lakes regions of the United States. It borders Delaware to its southeast, Maryland to its south, West Virginia to its southwest, Ohio and the Ohio River to its west, Lake Erie and New York (state), New York to its north, the Delaware River and New Jersey to its east, and the Provinces and territories of Canada, Canadian province of Ontario to its northwest via Lake Erie. Pennsylvania's most populous city is Philadelphia. Pennsylvania was founded in 1681 through a royal land grant to William Penn, the son of William Penn (Royal Navy officer), the state's namesake. Before that, between 1638 and 1655, a southeast portion of the state was part of New Sweden, a Swedish Empire, Swedish colony. Established as a haven for religious and political tolerance, the B ...

Lima Locomotives
Lima ( ; ), founded in 1535 as the Ciudad de los Reyes (, Spanish for "City of Kings"), is the capital and largest city of Peru. It is located in the valleys of the Chillón, Rímac and Lurín Rivers, in the desert zone of the central coastal part of the country, overlooking the Pacific Ocean. The city is considered the political, cultural, financial and commercial center of Peru. Due to its geostrategic importance, the Globalization and World Cities Research Network has categorized it as a "beta" tier city. Jurisdictionally, the metropolis extends mainly within the province of Lima and in a smaller portion, to the west, within the Constitutional Province of Callao, where the seaport and the Jorge Chávez Airport are located. Both provinces have regional autonomy since 2002. The 2023 census projection indicates that the city of Lima has an estimated population of 10,092,000 inhabitants, making it the second-most populous city in the Americas. Together with the seaside c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

ALCO Locomotives
The American Locomotive Company (often shortened to ALCO, ALCo or Alco) was an American manufacturer that operated from 1901 to 1969, initially specializing in the production of locomotives but later diversifying and fabricating at various times diesel generators, automobiles, steel, tanks, munitions, oil-production equipment, as well as heat exchangers for nuclear power plants. The company was formed by the merger of seven 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. After World War II, Alco closed all of its manufacturing plants except those in Schenectady and Montreal. In 1955, the company changed its name to Alco Products, Incorporated. In 1964, the Worthington Corporation acquired the company. The company wen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRR D16
Class D16 on the Pennsylvania Railroad was their final development of the "American" type of steam locomotive. A total of 429 of these locomotives were built at the PRR's Juniata Shops, spread across five subclasses; some had diameter driving wheels for service in level territory, while others had drivers for mountainous terrain. In the pre-1895 scheme, these locomotives were second class L. Construction continued until 1910, and the locomotives, aided by a rebuild program from 1914, remained in service in large numbers until the 1930s, a small number surviving into the 1940s. One locomotive, #1223, was preserved and is currently on display. Design These locomotives were originally conceived as an enlargement of the earlier class P (later reclassified D14) and were an extremely large and powerful locomotive for the period. Breaking with the traditional 4-4-0 layout with a low-slung boiler and the firebox between the frames, the class L design had a large Belpaire firebo ...
