PRR Q1
The Pennsylvania Railroad class Q1, #6130, was a single experimental steam locomotive designed for dual service. The locomotive entered service in 1942, and retired in 1949 after accumulating a relatively low 165,000 service miles. The Q1 had a 4-6-4-4 wheel arrangement, consisting of a four-wheel leading truck, two sets of driving wheels (six and four) in a rigid locomotive frame, and a four-wheel trailing truck. The first group of six driving wheels were powered by a pair of conventional front-mounted cylinders, while the rear four driving wheels had their cylinders mounted behind them, on either side of the firebox. The driving wheels were , larger than the PRR's existing dual-service locomotives. The Q1's streamlined design consisted of a blunt nosecone in front of the smokebox, extended side skirts covering the locomotive's pipework, and a streamlined shape on the tender similar to the PRR's S1, S2, and T1 passenger locomotives. The cab front was set at a rakish angle. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Railroad
The Pennsylvania Railroad (reporting mark PRR), legal name 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. It was named for the commonwealth in which it was established. By 1882, Pennsylvania Railroad had become the largest railroad (by traffic and revenue), the largest transportation enterprise, and the largest corporation in the world. Its budget was second only to the U.S. government. Over the years, it 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, T ...

PRR S2
The Pennsylvania Railroad's S2 class was a steam turbine locomotive designed and built in a collaborative effort by Baldwin Locomotive Works and Westinghouse Electric & Manufacturing Company, as an attempt to prolong the dominance of the steam locomotive by adapting technology that had been widely accepted in the marine industry. One was built, #6200, delivered in September 1944. The S2 was the sole example of the 6-8-6 wheel arrangement in the Whyte notation, with a six-wheel leading truck, eight driving wheels, and a six-wheel trailing truck. The S2 used a direct-drive steam turbine provided by the Westinghouse Electric & Manufacturing Company, geared to the center pair of axles with the outer two axles connected by side rods; the fixed gear ratio was 18.5:1. Such design was to prevent energy loss and S2 achieved a mechanical efficiency of 97% which means only 3% of steam energy was lost within the propulsion equipment. The disadvantage of direct-drive steam turbine was that the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Columbus, Ohio
Columbus () is the state capital and the most populous city in the U.S. state of Ohio. With a 2020 census population of 905,748, it is the 14th-most populous city in the U.S., the second-most populous city in the Midwest, after Chicago, and the third-most populous state capital. Columbus is the county seat of Franklin County; it also extends into Delaware and Fairfield counties. It is the core city of the Columbus metropolitan area, which encompasses 10 counties in central Ohio. The metropolitan area had a population of 2,138,926 in 2020, making it the largest entirely in Ohio and 32nd-largest in the U.S. Columbus originated as numerous Native American settlements on the banks of the Scioto River. Franklinton, now a city neighborhood, was the first European settlement, laid out in 1797. The city was founded in 1812 at the confluence of the Scioto and Olentangy rivers, and laid out to become the state capital. The city was named for Italian explorer Christopher Columbus. ...

Enola Yard
Enola Yard is a large rail yard located in East Pennsboro Township, Pennsylvania, along the western shore of the Susquehanna River at Harrisburg, Pennsylvania. Built in 1905 and expanded through the 1930s, Enola was the world's largest freight yard in 1956. It remains in operation today, though it has long since been eclipsed in size and traffic, first by Conway Yard outside Pittsburgh and later by Bailey Yard in Nebraska. History The yard was built by the Pennsylvania Railroad (PRR) in 1905 with two hump classification yards. Initially, the yard processed 7,000 cars per day. The westbound complex had a 20-track receiving yard and 25 classification tracks; the eastbound, a 21-track receiving yard and 17 classification tracks. There were no separate departure yards. By the late 1920s, Enola encompassed 316 acres and had a capacity of 9,692 cars. Service buildings included a 43-stall roundhouse and a steel car shop. A 240-car yard to handle container freight was added to the comp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Grand Trunk Western
The Grand Trunk Western Railroad Company is an American subsidiary of the Canadian National Railway operating in Michigan, Illinois, Indiana, and Ohio. Since a corporate restructuring in 1971, the railroad has been under CN's subsidiary holding company, the Grand Trunk Corporation. Grand Trunk Western's routes are part of CN's Michigan Division. Its primary mainline between Chicago and Port Huron, Michigan serves as a connection between railroad interchanges in Chicago and rail lines in eastern Canada and the Northeastern United States. The railroad's extensive trackage in Detroit and across southern Michigan has made it an essential link for the automotive industry as a hauler of parts and automobiles from manufacturing plants. Early history Grand Trunk Western grew out of a collection of 19th century Michigan rail lines which included: *Bay City Terminal Railway *Chicago, Detroit and Canada Grand Trunk Junction Railroad *Chicago and Grand Trunk Railway *Chicago, Kala ...

Duplex Locomotive
A duplex locomotive is a steam locomotive that divides the driving force on its wheels by using two pairs of cylinders rigidly mounted to a single locomotive frame; it is not an articulated locomotive. The concept was first used in France in 1863, but was particularly developed in the early 1930s by the Baldwin Locomotive Works, the largest commercial builder of steam locomotives in North America, under the supervision of its then chief engineer, Ralph P. Johnson. Prior to this, the term ''duplex locomotive'' was sometimes applied to articulated locomotives in general. Drawbacks of the two-cylinder locomotive The duplex solution In Europe this problem was often overcome by dividing the drive between inside and outside cylinders, or else by using Articulated locomotives, although at the time it was not believed possible to run one stably at greater than . American railroads proved to be unwilling to use locomotives with inside cylinders, so the problem of balance could not ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Raymond Loewy
Raymond Loewy ( , ; November 5, 1893 – July 14, 1986) was a French-born American industrial designer who achieved fame for the magnitude of his design efforts across a variety of industries. He was recognized for this by ''Time'' magazine and featured on its cover on October 31, 1949. He spent most of his professional career in the United States, becoming a naturalized citizen in 1938. Among his designs were the Shell, Exxon, TWA and the former BP logos, the Greyhound Scenicruiser bus, Coca-Cola vending machines and bottle redesign, the Lucky Strike package, Coldspot refrigerators, the Studebaker Avanti and Champion, and the Air Force One livery. He was engaged by equipment manufacturer International Harvester to overhaul its entire product line, and his team also assisted competitor Allis-Chalmers.

PRR Q2
The Pennsylvania Railroad's class Q2 comprised one prototype and twenty-five production duplex steam locomotives of 4-4-6-4 wheel arrangement. They were the largest non- articulated locomotives ever built and the most powerful locomotives ever static tested, producing 7,987 cylinder horsepower (5,956 kW) on the PRR's static test plant. They were by far the most successful duplex type. The duplex propensity to slip was combated by an automatic slip control mechanism that reduced power to the slipping unit. The Q2 locomotive was 78% more powerful than the locomotives that PRR had in service at the time, and the company claimed the Q2 could pull 125 freight cars at a speed of .
