Pennsylvania Railroad Class 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 mainly 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 typ ...

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, Pennsylvania, 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 locomotive, steam, diesel locomotive, diesel and electric locomotives were manufactured in Altoona between 1866 and 1946. In time, additional PRR repair faci ...

PRR DD2
The Pennsylvania Railroad's class DD2 was a single prototype electric 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 was only ...

PRR R1
The Pennsylvania Railroad's class R1 comprised a single prototype electric locomotive constructed in 1934 by the Baldwin Locomotive Works of Philadelphia, Pennsylvania, US, with the electrical equipment by Westinghouse. It was built as a competitor to the GG1 design, but after trials the GG1 was selected for volume production on the basis of its superior tracking and riding qualities; the R1 prototype, however, remained in service. It was numbered 4800 originally, swapped numbers with the victorious GG1 prototype to #4899, but was moved in May 1940 to #4999 to make room for the expanding GG1 fleet. For many years, the R1's regular duties involved hauling the westbound Broadway Limited and returning eastward with a mail and express train. The long rigid wheelbase of the locomotive caused occasional derailments in Sunnyside Yard and elsewhere. The R1 design had four driven axles in a rigid locomotive frame, like a steam locomotive. Each was driven by two traction motors driv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 or the road etc. 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. Road-grade crossings are considered incompatible with high-speed rail and are virtually non-existent in European high-speed train operations.

PRR K4s
The Pennsylvania Railroad K4 was a class of 425 4-6-2 steam locomotives built between 1914 and 1928 for the Pennsylvania Railroad (PRR), where they served as the primary mainline passenger steam locomotives on the entire PRR system until late 1957. Attempts were made to replace the K4s, including the K5 and the T1 duplex locomotive. However, the low factor-of-adhesion of K5s meant that they were limited in their pulling power. By contrast, the T1s were more powerful but suffered from greater maintenance costs, wheel slip due to poor springing, and inexperienced crews. The T1s were also introduced late into the lifetime of steam locomotives. As such, the tried and tested K4s held their role as the PRR's primary express passenger locomotives for 30-40 years. 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 wer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PRR E6
The Pennsylvania Railroad Class E6 was the final type of "Atlantic" locomotive built for the company, and second only to the Milwaukee Road's streamlined class A in size, speed and power. Although quickly replaced on the fastest trains by the larger K4s Pacifics, the E6 remained a popular locomotive on lesser services and some lasted until 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 PRR's General Superintendent of Motive Power, Lines East, Alfred W. Gibbs, and his team. They produced an Atlantic of modern ... [...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 u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boxcab
A boxcab, in railroad terminology, is a term for an electric locomotive in which the machinery and cab (locomotive), crew areas were enclosed in a box-like superstructure. Deriving from "boxcar", the term mainly occurs in North America. The term has rarely been applied to diesel locomotives. It was also applied in Australia to Victorian Railways' Victorian Railways E class (electric)#Design modification, "E" class second series electric locomotives. Boxcabs could also be diesel locomotives such as the case of the many AGEIR (ALCO boxcab, Alco, GE boxcab, General Electric, Ingersoll-Rand) boxcabs, but the overwhelming majority of them were electric. Most North American boxcabs were built a few years before and after 1930, the most prominent builders being Baldwin–Westinghouse electric locomotives, Baldwin and Westinghouse, GE and Alco. Design Locomotives had either a box-like body of equal height along their whole length including the cabs, the boxcab; or else the cabs were ...

Whyte Notation
The 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, 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. However, geared steam locomotives do not use the notation. They are classified by their model and their number of trucks. 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 ...
