PRR P5
The Pennsylvania Railroad's class P5 comprised 92 mixed-traffic electric locomotives constructed 1931–1935 by the PRR, Westinghouse and General Electric. Although the original intention was that they work many passenger trains, the success of the GG1 locomotives meant that the P5 class were mostly used on freight. A single survivor, prototype #4700, is at the National Museum of Transportation in St Louis, Missouri. They had an AAR wheel arrangement of 2-C-2, or 2′ in the UIC classification system — three pairs of driven wheels rigidly mounted to the locomotive, with a two-axle unpowered truck at each end. This is an equivalent to a 4-6-4 in the Whyte notation. The PRR did not have any 4-6-4 steam locomotives, so the P5s were the only 4-6-4 type locomotives owned by the PRR. The first P5s were built with box cabs. A grade crossing accident in which the crew were killed led to the substitution of a central cab to give better crash protection, a streamlined steeple type, ...

Altoona Works
Altoona Works (also known as Altoona Terminal) is a large railroad industrial complex in Altoona, Pennsylvania. It was built between 1850 and 1925 by the Pennsylvania Railroad (PRR), to supply the railroad with locomotives, railroad cars and related equipment. For many years, it was the largest railroad shop complex in the world. History In 1849, PRR officials developed plans to construct a repair facility at a town newly established for this purpose, Altoona. Construction was started in 1850, and soon a long building was completed in the 12th Street area that housed a machine shop, woodworking shop, blacksmith shop, locomotive repair shop and foundry. The 12th Street area facilities were replaced later by the Altoona Machine Shops. The first locomotive was built there in 1866. A total of 6,783 steam, diesel and electric locomotives were manufactured in Altoona between 1866 and 1946. In time, additional PRR repair facilities were located in Harrisburg, Pittsburgh, Renovo and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
St Louis, Missouri
St. Louis () is the second-largest city in Missouri, United States. It sits near the confluence of the Mississippi and the Missouri Rivers. In 2020, the city proper had a population of 301,578, while the bi-state metropolitan area, which extends into Illinois, had an estimated population of over 2.8 million, making it the largest metropolitan area in Missouri and the second-largest in Illinois. Before European settlement, the area was a regional center of Native American Mississippian culture. St. Louis was founded on February 14, 1764, by French fur traders Gilbert Antoine de St. Maxent, Pierre Laclède and Auguste Chouteau, who named it for Louis IX of France. In 1764, following France's defeat in the Seven Years' War, the area was ceded to Spain. In 1800, it was retroceded to France, which sold it three years later to the United States as part of the Louisiana Purchase; the city was then the point of embarkation for the Corps of Discovery on the Lewis and Clark Ex ...

PRR DD2
The Pennsylvania Railroad's class DD2 electric locomotive was a single prototype locomotive never placed into series production. It was intended as an improved and simplified GG1 for use on the planned, but never built, extension of the PRR's electrification west of Harrisburg, Pennsylvania. The one locomotive produced was numbered #5800 and used in regular Baltimore tunnel helper service until it was scrapped in September 1962. Design, construction and testing On May 21, 1937, a meeting was held in Philadelphia to outline the design of a new electric freight locomotive. The meeting was attended by the PRR and Baldwin, as well as electrical suppliers General Electric and Westinghouse, and the transportation engineering firm Gibbs & Hill, who were consultants on the proposal to extend electrification to Pittsburgh. The locomotive being designed was what became the DD2. Technical details Although the design specified either passenger gearing or freight gearing, the prototype ...

Grade Crossing
A level crossing is an intersection where a railway line crosses a road, path, or (in rare situations) airport runway, at the same level, as opposed to the railway line crossing over or under using an overpass or tunnel. The term also applies when a light rail line with separate right-of-way or reserved track crosses a road in the same fashion. Other names include railway level crossing, railway crossing (chiefly international), grade crossing or railroad crossing (chiefly American), road through railroad, criss-cross, train crossing, and RXR (abbreviated). There are more than 100,000 level crossings in Europe and more than 200,000 in North America. History The history of level crossings depends on the location, but often early level crossings had a flagman in a nearby booth who would, on the approach of a train, wave a red flag or lantern to stop all traffic and clear the tracks. Gated crossings became commonplace in many areas, as they protected the railway fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Erie, Pennsylvania
Erie (; ) is a city on the south shore of Lake Erie and the county seat of Erie County, Pennsylvania, United States. Erie is the fifth largest city in Pennsylvania and the largest city in Northwestern Pennsylvania with a population of 94,831 at the 2020 census. The estimated population in 2021 had decreased to 93,928. The Erie metropolitan area, equivalent to all of Erie County, consists of 266,096 residents. The Erie-Meadville combined statistical area had a population of 369,331 at the 2010 census. Erie is roughly equidistant from Buffalo and Cleveland, each being about 100 miles (160 kilometers) away. Erie's manufacturing sector remains prominent in the local economy, though insurance, healthcare, higher education, technology, service industries, and tourism are emerging as significant economic drivers. As with the other Great Lakes port cities, Erie is accessible to the oceans via the Lake Ontario and St. Lawrence River network in Canada. The local climate is humid, ...

PRR 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. 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 l ...

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] |
PRR O1
The Pennsylvania Railroad's class O1 comprised eight experimental boxcab electric locomotives built in 1930 and 1931. They were built in preparation for the New York to Washington Electrification project. They had the wheel arrangement classified as 4-4-4 in the Whyte notation ( UIC: 2'B2'; AAR: 2-B-2). Although successful, they were not powerful enough for the railroad's increasingly heavy trains. For production, the PRR chose to concentrate on the P5 class, effectively an enlarged and more powerful version of the O1 with an additional pair of driving wheels. The eight locomotives were divided into four sub-classes — O1, O1a, O1b, and O1c. Each sub-class was fitted with a different combination of traction motor power output and drive gear ratio. In addition, three O1 locomotives were fitted with General Electric equipment, three with Westinghouse, and two with Brown Boveri. The O1b locomotives used a Buchli drive between the traction motors and the driving wheels. were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boxcab
A boxcab, in railroad terminology, is a locomotive in which the machinery and crew areas are enclosed in a box-like superstructure (from boxcar). It is a term mostly used in North America while in Victoria (Australia), such locomotives have been nicknamed "butterboxes" (Victorian Railways second series "E" Class electric locomotives numbered E1102 to E1111). Boxcabs may use any source of power but most are diesel or electric locomotives. Few steam locomotives are so described but the British SR Leader class was a possible exception. Most American boxcabs date from before World War II, when the earliest boxcabs were often termed "oil-electrics" to avoid the use of the German name "Diesel" due to propaganda purposes. Styling Boxcabs do not have heavily styled ends, or a superstructure consisting of multiple boxy structures, although the prototype diesel/oil-electric, GE #8835, had one prominently-rounded nose (from its trolley (tram) car ancestry) and the second and following 10 ...

Whyte Notation
Whyte notation is a classification method for steam locomotives, and some internal combustion locomotives and electric locomotives, by wheel arrangement. It was devised by Frederick Methvan Whyte, and came into use in the early twentieth century following a December 1900 editorial in ''American Engineer and Railroad Journal''. The notation was adopted and remains in use in North America and the United Kingdom to describe the wheel arrangements of steam locomotives (in the latter case also for diesel and electric locomotives), but for modern locomotives, multiple units and trams it has been supplanted by the UIC system in Europe and by the AAR system (essentially a simplification of the UIC system) in North America. Structure of the system Basic form The notation in its basic form counts the number of leading wheels, then the number of driving wheels, and finally the number of trailing wheels, numbers being separated by dashes. For example, a locomotive with two leadi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
