PRR BB2
The Pennsylvania Railroad's class B1 comprised 42 switcher-type electric locomotives built between 1926 and 1935. They were of 0-6-0 wheel arrangement in the Whyte notation with 700 horsepower. As built, the first 28 locomotives in the 1926 order formed semi-permanently coupled pairs grouped in three classes. The first, class BB1, were AC powered and served as prototypes. The second, class BB2, were DC powered and served in the New York Terminal district, specifically between Sunnyside Yard and New York Penn Station. The third, class BB3, was AC powered and built for the Long Island Rail Road's electrified freight operation on the Bay Ridge Branch. In 1934 a follow-up order of 14 locomotives were built as single unit class B1 for the expanding main line AC electrification system. In addition to these new units all previous BB classes were split into single units and the BB2 class were re-powered for AC operation as that system replaced the old 650 V DC system in the New ...

The Railroad Museum of Pennsylvania was created to provide a historical account of railroading in Pennsylvania by preserving rolling stock, artifacts, and archives of railroad companies of the Commonwealth. However, the museum has branched out over the years, acquiring some pieces that are not directly related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack o ...

Penn Central
The Penn Central Transportation Company, commonly abbreviated to Penn Central, was an American class I railroad that operated from 1968 to 1976. Penn Central combined three traditional corporate rivals (the Pennsylvania, New York Central and the New York, New Haven and Hartford railroads), all united by heavy service into the New York metropolitan area and (to a lesser extent) New England and Chicago. The new company failed barely two years after formation, the largest bankruptcy in U.S. history at the time. The Penn Central's railroad assets were nationalized into Conrail along with the other bankrupt northeastern roads; its real estate and insurance holdings successfully reorganized into American Premier Underwriters. History Pre-merger The Penn Central railroad system developed in response to challenges facing northeastern American railroads during the late 1960s. While railroads elsewhere in North America drew revenues from long-distance shipments of commodities ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Harrisburg Transportation Center
The Harrisburg Transportation Center (HTC, formerly Pennsylvania Station, Harrisburg or Harrisburg Central Railroad Station) is a large railway station and transportation hub in Harrisburg, Pennsylvania. It is located on the eastern edge of Downtown Harrisburg between the intersections of Aberdeen and Market Streets and 4th and Chestnut Streets. The well-situated station is the primary hub for passenger rail and intercity bus services in the Harrisburg metropolitan area and South Central Pennsylvania. History The current station is the third on the site. Though technically a union station (meaning it was used by several railways), it was never identified as such in publications such as the Official Guide of the Railroads and Steam Navigation Lines or Pennsylvania Railroad Timetables. The first two stations were shared by the Pennsylvania Railroad (PRR), Reading Railroad, Northern Central Railway (NCR), and the Cumberland Valley Railroad (CVR). The third (and current) statio ...

30th Street Station
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9 ...

Bay Ridge Branch
The Bay Ridge Branch is a rail line owned by the Long Island Rail Road (LIRR) and operated by the New York and Atlantic Railway in New York City. It is the longest freight-only line of the LIRR, connecting the Montauk Branch and CSX Transportation's Fremont Secondary (to the Hell Gate Bridge) at Glendale, Queens with the Upper New York Bay at Bay Ridge, Brooklyn. Car float service provided by New York New Jersey Rail operates between Greenville Yard at Greenville, Jersey City and the 65th Street Yard at the Bay Ridge end of the line. History Early history The first part of the line was opened by the New York, Bay Ridge and Jamaica Railroad in 1876, from Bay Ridge to the crossing of the Brooklyn, Bath and Coney Island Railroad near New Utrecht. , April 2005 Edition An extension from New Utrecht east and northeast to New Lots opened in 1877, and at the same time the New York and Manhattan Beach Railway opened the line from New Lots north to East New York. , ...

Long Island Rail Road
The Long Island Rail Road , often abbreviated as the LIRR, is a commuter rail system in the southeastern part of the U.S. state of New York, stretching from Manhattan to the eastern tip of Suffolk County on Long Island. With an average weekday ridership of 354,800 passengers in 2016, it is the busiest commuter railroad in North America. It is also one of the world's few commuter systems that runs 24/7 year-round. It is publicly owned by the Metropolitan Transportation Authority, which refers to it as MTA Long Island Rail Road. In , the system had a ridership of , or about per weekday as of . The LIRR logo combines the circular MTA logo with the text ''Long Island Rail Road'', and appears on the sides of trains. The LIRR is one of two commuter rail systems owned by the MTA, the other being the Metro-North Railroad in the northern suburbs of the New York area. Established in 1834 and having operated continuously since then, it is the oldest railroad in the United States s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pennsylvania Station (1910–1963)
Pennsylvania Station, often abbreviated to Penn Station, was a historic railroad station in New York City, named for the Pennsylvania Railroad (PRR), its builder and original tenant. The station occupied an plot bounded by Seventh and Eighth Avenues and 31st and 33rd Streets in Midtown Manhattan. As the station shared its name with several stations in other cities, it was sometimes called New York Pennsylvania Station. The building was designed by McKim, Mead, and White and completed in 1910, enabling direct rail access to New York City from the south for the first time. Its head house and train shed were considered a masterpiece of the Beaux-Arts style and one of the great architectural works of New York City. The station contained 11 platforms serving 21 tracks, in approximately the same layout as the current Penn Station. The original building was one of the first stations to include separate waiting rooms for arriving and departing passengers, and when built, these ...

Sunnyside Yard
Sunnyside Yard is a large coach yard, a railroad yard for passenger cars, in Sunnyside, Queens in New York City. Description The yard is owned by Amtrak and is also used by New Jersey Transit. The shared tracks of the Long Island Rail Road (LIRR) Main Line and Amtrak's Northeast Corridor pass along the southern edge of the yard. Northeast of the yard a balloon track (or reverse loop) is used for "U-turning" Amtrak and NJ Transit trains which terminate at Penn Station. Leading eastward near the south side of the yard, this balloon track switches off and turns left under the LIRR/Amtrak tracks, turns left once again, and merges with the Sunnyside yard track to turn the train west toward Penn Station. History The Pennsylvania Railroad (PRR) completed construction of the yard in 1910. At that time Sunnyside was the largest coach yard in the world, occupying 192 acres (0.78 km2) and containing 25.7 mi (41.4 km) of track. The yard served as the main train storage and ...

Married Pair
A twin unit or twinset is a set of two railroad cars or locomotives which are permanently coupled and treated as if they were a single unit. A twinset of cars or coaches can also be called a twin car. In US passenger railroad parlance, twin units are also known as married pairs. On passenger railroads, light rail, and monorail services, married pairs may have machinery necessary for full operation of the cars split between them. Items that are typically shared include transformers, motor controllers, dynamic braking grids, cabs, current collectors, batteries, and air compressors. This provides significant savings in both cost of equipment and weight, which increases performance and decreases energy consumption. The cost of operating such a pair may be slightly higher when the extra car in such a pair is not needed to meet level-of-service demands at a particular time.

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 lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wheel Arrangement
In rail transport, a wheel arrangement or wheel configuration is a system of classifying the way in which wheels are distributed under a locomotive. Several notations exist to describe the wheel assemblies of a locomotive by type, position, and connections, with the adopted notations varying by country. Within a given country, different notations may also be employed for different kinds of locomotives, such as steam, electric, and diesel powered. Especially in steam days, wheel arrangement was an important attribute of a locomotive because there were many different types of layout adopted, each wheel being optimised for a different use (often with only some being actually "driven"). Modern diesel and electric locomotives are much more uniform, usually with all axles driven. Major notation schemes The main notations are the Whyte notation (based on counting the wheels), the AAR wheel arrangement notation (based on counting either the axles or the bogies), and the UIC classific ...
