Putnam Bridge (New York City)
The Putnam Bridge was a swing bridge that spanned the Harlem River and the adjacent tracks of the New York Central Railroad in New York City. The bridge connected Harlem in Manhattan to Concourse, near the current location of Yankee Stadium, in the Bronx. It carried two tracks of the New York and Putnam Railroad, and later the 9th Avenue elevated line of the Interborough Rapid Transit Company (IRT), as well as two pedestrian walkways outside the superstructure. The bridge opened to rail and pedestrian traffic on May 1, 1881, and operated until all rail service was discontinued on August 31, 1958. The bridge's extreme narrowness of between the centers of the trusses, combined with the proximity of the Macombs Dam Bridge, made it impractical and unnecessary to convert to a roadway bridge, and it was removed in 1960. Design As with the other Harlem River swing bridges, the bridge was designed by Chief Engineer Alfred Pancoast Boller; the contractors were Clarke, Reeves & Co., ...

Putnam Division
The New York and Putnam Railroad, nicknamed the Old Put, was a railroad line that operated between the Bronx and Brewster in New York State. It was in close proximity to the Hudson River Railroad and New York and Harlem Railroad. All three came under ownership of the New York Central system in 1894. The railroad was abandoned starting in 1958, and most of the former roadbed has been converted to rail trail use. History Early years, charter The New York & Boston Railroad (NY&B) was chartered on May 21, 1869 to build a line from Highbridge on the Harlem River in New York northeast to Brewster. At Brewster connections were to be provided to the New York & Harlem Railroad for travel north to Albany, and to the Boston, Hartford & Erie Railroad to Boston. The New York, Boston & Northern Railway (NYB&N) was formed on November 18, 1872, as a consolidation of the NY&B with two companies to the north — the Putnam & Dutchess Railroad (P&D) and Dutchess & Columbia Railroad ( ...

Superstructure
A superstructure is an upward extension of an existing structure above a baseline. This term is applied to various kinds of physical structures such as buildings, bridges, or ships. Aboard ships and large boats On water craft, the superstructure consists of the parts of the ship or a boat, including sailboats, fishing boats, passenger ships, and submarines, that project above her main deck. This does not usually include its masts or any armament turrets. Note that in modern times, turrets do not always carry naval artillery, but they can also carry missile launchers and/or antisubmarine warfare weapons. The size of a watercraft's superstructure can have many implications in the performance of ships and boats, since these structures can alter their structural rigidity, their displacements, and/or stability. These can be detrimental to any vessel's performance if they are taken into consideration incorrectly. The height and the weight of superstructure on board a ship or a bo ...

155th Street Station (IRT Ninth Avenue Line)
The 155th Street station was an elevated railway station in Manhattan, New York City, that operated from 1870 until 1958. It served as the north terminal of the IRT Ninth Avenue Line from its opening until 1918 and then as the southern terminal of a surviving stub portion from 1940 until its closure in 1958. It had two tracks and one island platform. History When the Ninth Avenue El was extended to Harlem in 1879 it terminated at 155th Street as a matter of geographic necessity (the hills of Washington Heights and Highbridge would have made an northward expansion difficult) and demand (northern Manhattan and the Bronx were still sparsely populated). Development came to the area with the New York City and Northern Railroad (later known as the Putnam Division) building its terminal at 155th Street in 1881 and the Polo Grounds relocating to a site just west of the station in 1889. The line expanded into The Bronx on June 1, 1918, when the Putnam Bridge, which had been built ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manhattan Railway Company
The Manhattan Railway Company was an elevated railway company in Manhattan and the Bronx, New York City, United States. It operated four lines: the Second Avenue Line, Third Avenue Line, Sixth Avenue Line, and Ninth Avenue Line. History 19th century By the late 1870s, the elevated railways in Manhattan were operated by two companies, the Metropolitan Elevated Railway (Sixth Avenue) and New York Elevated Railroad (Third and Ninth Avenues). The Metropolitan also began constructing a line above Second Avenue. The Manhattan Railway Company was chartered on December 29, 1875, and leased both companies on May 20, 1879. The company was the subject of investigation by the New York State Legislature's Hepburn Committee which exposed a scheme that involved barely legal business practices and massive watering of the company's stock in order to raise its nominal value from $2 million to $15 million. The exposure of the shady business practices of the company led the Hepburn Comm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hudson Line (Metro-North)
Metro-North Railroad's Hudson Line is a commuter rail line running north from New York City along the east shore of the Hudson River. Metro-North service ends at Poughkeepsie, with Amtrak's Empire Corridor trains continuing north to and beyond Albany. The line was originally the Hudson River Railroad (and the Spuyten Duyvil and Port Morris Railroad south of Spuyten Duyvil), and eventually became the Hudson Division of the New York Central Railroad. It runs along what was the far southern leg of the Central's famed "Water Level Route" to Chicago. Croton–Harmon station divides the line into two distinct segments. South of there, the line is electrified with third rail, serving suburban stations located relatively close together. Most of the electrified zone has four tracks, usually two express and local tracks in each direction. For a few miles in the Bronx there are only two or three tracks. Local service is usually provided by electric trains, while diesel trains run expre ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sedgwick Avenue Station
The Sedgwick Avenue station was an elevated, ground level and underground station on the Bronx extension of the IRT Ninth Avenue Line in Highbridge, Bronx, New York City. History The station was built to connect to the New York & Putnam Railroad passenger trains that terminated there instead of the former 155th Street terminal and New York Central Railroad Hudson Division trains that stopped at the new (1918) platforms at this location. The station opened on July 1, 1918, and remained in use by the Polo Grounds Shuttle until 1958. The Putnam Division of the New York Central also ended service in 1958. Station layout The station was built extending from the tunnel entrance to Jerome Avenue on the side of a cliff on a steel structure spanning the tracks of Metro-North's Hudson Line that connected to the existing Putnam Bridge, which had been built for the New York City and Northern Railroad. The station street entrance and mezzanine was above the tracks on Sedgwick Avenue. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Truss
A truss is an assembly of ''members'' such as beams, connected by ''nodes'', that creates a rigid structure. In engineering, a truss is a structure that "consists of two-force members only, where the members are organized so that the assemblage as a whole behaves as a single object". A "two-force member" is a structural component where force is applied to only two points. Although this rigorous definition allows the members to have any shape connected in any stable configuration, trusses typically comprise five or more triangular units constructed with straight members whose ends are connected at joints referred to as ''nodes''. In this typical context, external forces and reactions to those forces are considered to act only at the nodes and result in forces in the members that are either tensile or compressive. For straight members, moments (torques) are explicitly excluded because, and only because, all the joints in a truss are treated as revolutes, as is necessary for ...

New York Rapid Transit Commission
The first regularly operated subway in New York City was opened on October 27, 1904, and was operated by the Interborough Rapid Transit Company (IRT). The early IRT system consisted of a single trunk line below 96th Street in Manhattan, running under Broadway, 42nd Street, Park Avenue, and Lafayette Street. The line had three northern branches in Upper Manhattan and the Bronx, and a southern branch to Brooklyn. The system had four tracks between Brooklyn Bridge–City Hall and 96th Street, allowing for local and express service. The original line and early extensions consisted of: * The IRT Eastern Parkway Line from Atlantic Avenue–Barclays Center to Borough Hall * The IRT Lexington Avenue Line from Borough Hall to Grand Central–42nd Street * The IRT 42nd Street Shuttle from Grand Central–42nd Street to Times Square * The IRT Broadway–Seventh Avenue Line from Times Square to Van Cortlandt Park–242nd Street * The IRT Lenox Avenue Line from 96th Street to 145th Str ...

Deck Truss
A truss bridge is a bridge whose load-bearing superstructure is composed of a truss, a structure of connected elements, usually forming triangular units. The connected elements (typically straight) may be stressed from tension, compression, or sometimes both in response to dynamic loads. The basic types of truss bridges shown in this article have simple designs which could be easily analyzed by 19th and early 20th-century engineers. A truss bridge is economical to construct because it uses materials efficiently. Design The nature of a truss allows the analysis of its structure using a few assumptions and the application of Newton's laws of motion according to the branch of physics known as statics. For purposes of analysis, trusses are assumed to be pin jointed where the straight components meet, meaning that taken alone, every joint on the structure is functionally considered to be a flexible joint as opposed to a rigid joint with strength to maintain its own shape, and th ...
