Booster Engine
A locomotive booster for steam locomotives is a small supplementary two-cylinder steam engine back-gear-connected to the trailing truck axle on the locomotive or one of the trucks on the tender. It was invented in 1918 by Howard L. Ingersoll, assistant to the president of the New York Central Railroad. A rocking idler gear permits the booster engine to be put into operation by the driver (engineer). A geared booster engine drives one axle only and can be non-reversible, with one idler gear, or reversible, with two idler gears. There were variations built by the Franklin company which utilized side rods to transmit tractive force to all axles of the booster truck. These rod boosters were predominately used on the leading truck of the tender, though there is an example of a Lehigh Valley 4-8-4 using it as a trailing tender truck. A booster engine is used to start a heavy train or maintain low speed under demanding conditions. Rated at about at speeds from , it can be cut in ...

Pounds Per Square Inch
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), is a unit of measurement of pressure or of stress based on avoirdupois units and used primarily in the United States. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately . The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victorian Railways
The Victorian Railways (VR), trading from 1974 as VicRail, was the state-owned operator of most rail transport in the Australian state of Victoria from 1859 to 1983. The first railways in Victoria were private companies, but when these companies failed or defaulted, the Victorian Railways was established to take over their operations. Most of the lines operated by the Victorian Railways were of . However, the railways also operated up to five Narrow gauge lines of the Victorian Railways, narrow gauge lines between 1898 and 1962, and a line between Albury railway station, Albury and Melbourne from 1961. History Formation A Department of Railways (1858–71), Department of Railways was created in 1856 with the first appointment of staff. British engineer, George Christian Darbyshire was made first Engineer-in-Chief in 1857, and steered all railway construction work until his replacement by Thomas Higinbotham in 1860. In late 1876, New York consulting engineer Walton Evans arran ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2-10-4
Under the Whyte notation for the classification of steam locomotives, a locomotive has two leading wheels on one axle, usually in a Bissel truck, ten coupled driving wheels on five axles, and four trailing wheels on two axles, usually in a bogie. These were referred to as the Texas type in most of the United States, the Colorado type on the Burlington Route, and the Selkirk type in Canada. Overview The Texas wheel arrangement originated and was principally used in the United States. The evolution of this locomotive type began as a Santa Fe type with a larger four-wheeled trailing truck that would allow an enlarged firebox. A subsequent development was as an elongated Berkshire type that required extra driving wheels to remain within axle load limits. Examples of both of these evolutionary progressions can be found. Some tank locomotives also existed in eastern Europe. One extraordinary experimental tender locomotive, built in the Soviet Union, had an opposed-pisto ...

Selkirk Locomotive
The Selkirk locomotives were 36 steam locomotives of the 2-10-4 wheel arrangement built for Canadian Pacific Railway by Montreal Locomotive Works, Montreal in Quebec, Canada. History The first of these large engines, which had a 2-10-4 wheel arrangement, was built in July 1929. Altogether, twenty were constructed before the end of this year bearing numbers 5900 to 5919. The Canadian Pacific Railway's classification was T1a. These locomotives weighed fully loaded. They were the largest and most powerful locomotives in the British Empire. While most other 2-10-4s were named after the state of Texas, these locomotives were named after the Selkirk range of mountains that they crossed, the (railway) summit of which was located just inside the western portal of the Connaught Tunnel beneath Rogers Pass. Montreal Locomotive Works built another ten of these successful Selkirk locomotives during November and December 1938. The Canadian Pacific Railway assigned them T1b class. They were ...

Royal Hudson
The Royal Hudsons are a series of semi-Streamliner, streamlined 4-6-4 "Hudson" type steam locomotives formerly owned and operated by the Canadian Pacific Railway (CPR) and built by Montreal Locomotive Works (MLW). The engines were built in 1937. In 1939, George VI of the United Kingdom, King George VI allowed the CPR to use the term after Royal Hudson number 2850 transported the Royal and viceroyal transport in Canada, royal train across Canada with no need of replacement. These locomotives were in service between 1937 and 1960. Four of them have been preserved. No. 2839 was used to power excursions for the Southern Railway (U.S.), Southern Railway Steam Program between 1979 and 1980. No. 2860 was used for Excursion train, excursion service in British Columbia between 1974 and 1999, then again between 2006 and 2010. Royal visit In 1939, King George VI and Queen Elizabeth Bowes-Lyon, Elizabeth visited Canada, arriving at Anse-au-Foulon, Wolfe's Cove, Quebec, on 17 May 1939. This wa ...

Canadian Pacific Railway
The Canadian Pacific Railway () , also known simply as CPR or Canadian Pacific and formerly as CP Rail (1968–1996), is a Canadian Class I railway incorporated in 1881. The railway is owned by Canadian Pacific Kansas City, Canadian Pacific Kansas City Limited, known until 2023 as Canadian Pacific Railway Limited, which began operations as legal owner in a corporate restructuring in 2001. The railway is headquartered in Calgary, Alberta. In 2023, the railway owned approximately of track in seven provinces of Canada and into the United States, stretching from Montreal to Vancouver, and as far north as Edmonton. Its rail network also served Minneapolis–St. Paul, Milwaukee, Detroit, Chicago, and Albany, New York, in the United States. The railway was first built between eastern Canada and British Columbia between 1875 and 1885 (connecting with Ottawa Valley and Georgian Bay area lines built earlier), fulfilling a commitment extended to British Columbia when it entered Canadia ...

Norfolk & Western
The Norfolk and Western Railway , commonly called the N&W, was a US class I railroad, formed by more than 200 railroad mergers between 1838 and 1982. It was headquartered in Roanoke, Virginia, for most of its existence. Its motto was "Precision Transportation"; it had a variety of nicknames, including "King Coal" and "British Railway of America". In 1986, N&W merged with Southern Railway to form today's Norfolk Southern Railway. The N&W was famous for manufacturing its own steam locomotives, which were built at the Roanoke Shops, as well as its own hopper cars. After 1960, N&W was the last major Class I railroad using steam locomotives; the last remaining Y class 2-8-8-2s would eventually be retired in 1961. In December 1959, the N&W merged with the Virginian Railway (reporting mark VGN), a longtime rival in the Pocahontas coal region. By 1970, other mergers with the Nickel Plate Road and Wabash formed a system that operated of road on of track from North Carolina to New ...

Chesapeake And Ohio Class H-8
The Chesapeake and Ohio class H-8 was a class of 60 simple articulated 2-6-6-6 steam locomotives built by the Lima Locomotive Works in Lima, Ohio between 1941 and 1948, operating until the mid 1950s. The locomotives were among the most powerful steam locomotives ever built and hauled fast, heavy freight trains for the railroad. Only two units were preserved; Nos. 1601 and 1604. History In 1939, the C&O was in the market for new locomotive power for its coal traffic. The railroad already had 40 Lima-built 2-10-4 T-1s from 1930 which ran across the largely level trackage in Ohio, while 45 2-8-8-2 H-7s dating back to 1924-1926 plodded away in mountainous territories of West Virginia and Virginia. Seemingly poised to order more Superpower T-1s, Norfolk & Western's success with their home-built Class A 2-6-6-4 prompted the C&O and Lima to consider a more modern articulated design. Design engineers at Lima argued that expanding the 4-wheeled trailing truck design to a 6-wheel desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superpower Steam
"Superpower steam" was a term coined by Lima Locomotive Works in the mid-1920s, referring to steam locomotives with booster-equipped four-wheel trailing trucks supporting large fireboxes, as well as enlarged superheaters. The wheel arrangements introduced in the 1920s for these locomotives were the 4-6-4s, 2-8-4s, 4-8-4s and 2-10-4s; and in the 1930s, the 2-6-6-4s. The term "superpower" was later often applied to all locomotives with 4-wheel trailing truck arrangements, though many did not have boosters and almost all steam of any wheel arrangement built after that time had large superheaters. The design was invented by Lima for the New York Central's Boston and Albany Railroad. The design was invented by Lima's Vice President of Engineering, William Woodard, who had experimented with a New York Central 2-8-2 Mikado in 1922. The new design called for double the firebox size than the earlier Mikados, thus giving it more grate area leading to the development of the 2-8-4. The large ...

Chesapeake And Ohio Railway
The Chesapeake and Ohio Railway was a Class I railroad formed in 1869 in Virginia from several smaller Virginia railroads begun in the 19th century. Led by industrialist Collis Potter Huntington, it reached from Virginia's capital city of Richmond to the Ohio River by 1873, where the railroad town (and later city) of Huntington, West Virginia, was named for him. History 19th century The C&O traces its origins to the Louisa Railroad of Louisa County, Virginia, begun in 1836. By 1850, the Louisa was built east to Richmond and west to Charlottesville, and in keeping with its new and larger vision, was renamed the Virginia Central Railroad. The Commonwealth of Virginia owned a portion of Virginia Central stock and financed the Blue Ridge Railroad to accomplish the task of crossing the first mountain barrier to the west. During the American Civil War, the Virginia Central played a key role in several battles but was a target for Federal armies. By 1865, it only had five mile ...

Pennsylvania Railroad
The Pennsylvania Railroad ( reporting mark PRR), legal name as the Pennsylvania Railroad Company, also known as the "Pennsy," was an American Class I railroad that was established in 1846 and headquartered in Philadelphia, Pennsylvania. At its peak in 1882, the Pennsylvania Railroad was the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Over its existence, Pennsylvania Railroad acquired, merged with, or owned part of at least 800 other rail lines and companies. At the end of 1926, it operated of rail line;This mileage includes companies independently operated. PRR miles of all tracks, which includes first (or main), second, third, fourth, and sidings, totalled 28,040.49 at the end of 1926. in the 1920s, it carried nearly three times the traffic as other railroads of comparable length, such as the Union Pacific and Atchison, Topeka & Santa Fe railroads. Its only formidable rival was the New York Centra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
