Zoo Interlocking
Zoo Junction is a junction on Amtrak's Northeast Corridor in Philadelphia, Pennsylvania where the Northeast Corridor meets the Keystone Corridor (ex-Pennsylvania Railroad main line). History Zoo Junction is a flying junction, where multiple tracks cross one another by bridges to avoid conflict with other trains. In 1870, the Pennsylvania Railroad built the Connecting Railway from Frankford Junction to Zoo to bypass congested street running in Philadelphia. Instead of reaching the city directly from the north, the Connecting Railway turned west, crossed the Schuylkill River on the Connecting Railway Bridge (a stone arch viaduct) and then turned south to join the PRR's Main Line at Mantua Junction. Mantua was a wye junction controlled by three manual signal boxes; there was also an engine house and the massive 37th Street Yard in the center of the wye. By 1888 the Mantua Junction was at capacity. In 1910 the PRR built two duck-under tunnels to allow trains to reach the C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Map Of ZOO Junction In Philadelphia
A map is a symbolic depiction emphasizing relationships between elements of some space, such as objects, regions, or themes. Many maps are static, fixed to paper or some other durable medium, while others are dynamic or interactive. Although most commonly used to depict geography, maps may represent any space, real or fictional, without regard to context or scale, such as in brain mapping, DNA mapping, or computer network topology mapping. The space being mapped may be two dimensional, such as the surface of the earth, three dimensional, such as the interior of the earth, or even more abstract spaces of any dimension, such as arise in modeling phenomena having many independent variables. Although the earliest maps known are of the heavens, geographic maps of territory have a very long tradition and exist from ancient times. The word "map" comes from the , wherein ''mappa'' meant 'napkin' or 'cloth' and ''mundi'' 'the world'. Thus, "map" became a shortened term referring to ...

Connecting Railway
The Connecting Railway was a subsidiary of the Pennsylvania Railroad, incorporated to build a connection between the Philadelphia and Trenton Railroad and the PRR in the city of Philadelphia. Construction and assembly Connecting Railway The PRR controlled the Philadelphia & Trenton, and had originally intended to directly connect the two lines through the heart of Philadelphia. However, attempts to buy out and demolish buildings in the right-of-way led to riots, and the Philadelphia & Trenton was forced to end at Kensington. To resolve the problem, Connecting Railway Company was incorporated May 15, 1863, and between 1864 and June 1867, constructed a connecting line between Frankford Junction on the Philadelphia & Trenton and Mantua Junction (now Zoo interlocking) on the PRR mainline, passing through what is now North Philadelphia. Bustleton Branch On July 18, 1863, the Frankford and Holmesburg Railroad was incorporated to build a line from Frankford to Holmesburg. This would h ...

Zoological Garden Station
Zoological Garden station was a railroad station in Philadelphia, Pennsylvania. It was located at 34th Street and Girard Avenue, it served the Philadelphia Zoo and nearby areas. Built by the Pennsylvania Railroad, it closed in 1902 as the railroad expanded. The zoo has proposed that a new station be created at 34th Street and Mantua, though the complicated network of tracks, known as Zoo interlocking, presents engineering challenges. The zoo, recognizing that SEPTA lacks the necessary resources, is seeking funding from the federal government.

Philadelphia Zoo
The Philadelphia Zoo, located in the Centennial District of Philadelphia on the west bank of the Schuylkill River, is the first true zoo in the United States. It was chartered by the Commonwealth of Pennsylvania on March 21, 1859, but its opening was delayed by the Civil War until July 1, 1874. The zoo opened with 1,000 animals and an admission price of 25 cents. For a brief time, the zoo also housed animals brought to U.S. from safaris by the Smithsonian Institution, which had not yet built its National Zoo. The Philadelphia Zoo is one of the premier zoos in the world for breeding animals that are difficult to breed in captivity. The zoo also works with many groups around the world to protect the natural habitats of the animals in their care. The zoo is and the home of nearly 1,300 animals, many of which are rare and endangered. Special features include a children's petting zoo, a paddleboat lake, a rainforest themed carousel, a ropes course, and many interactive and educati ...

Suburban Station
Suburban Station is an art deco office building and underground commuter rail station in Penn Center, Philadelphia. Its official SEPTA address is 16th Street and JFK Boulevard. The station is owned and operated by SEPTA and is one of the three core Center City stations on SEPTA Regional Rail, and is also the busiest station in the Regional Rail network. The station was built by the Pennsylvania Railroad to replace the original Broad Street Station and opened on September 28, 1930. History The station opened as a stub-end terminal for Pennsylvania Railroad suburban commuter trains serving Center City Philadelphia, intended to replace the above-ground Broad Street Station in this function. PRR inter-city trains, on the other hand, would use Thirtieth Street Station. The station's full name was originally Broad Street Suburban Station. It also includes a 21-story office tower, One Penn Center, which served as the headquarters of the PRR from 1930 to 1957. When Amtrak took ov ...

Interlocking
In railway signalling, an interlocking is an arrangement of signal apparatus that prevents conflicting movements through an arrangement of tracks such as junction (rail), junctions or crossings. The signalling appliances and Track (rail transport), tracks are sometimes collectively referred to as an ''interlocking plant''. An interlocking is designed so that it is impossible to display a signal to proceed unless the route to be used is proven safe. Interlocking is a safety measure designed to prevent signals and Railroad switch, points/switches from being changed in an improper sequence. For example interlocking would prevent a signal from being changed to indicate a diverging route, unless the corresponding points/switches had been changed first. In North America, the official railroad definition of interlocking is: "''An arrangement of signals and signal appliances so interconnected that their movements must succeed each other in proper sequence''".

Broad Street Station (Philadelphia)
Broad Street Station at Broad & Market streets was the primary passenger terminal for the Pennsylvania Railroad (PRR) in Philadelphia from early December 1881 to the 1950s. Located directly west of Philadelphia City Hall—15th Street went underneath the station—the site is now occupied by the northwest section of Dilworth Park and the office towers of Penn Center. History The original station was designed by Wilson Brothers & Company under authority of the old Philadelphia, Wilmington and Baltimore Railroad (established 1836 from merger of four smaller segment lines dating to 1831, running southwest to Baltimore and its President Street Station which had just been purchased by the Pennsylvania Railroad assuming control) in the same year of completion in 1881. It was one of the first steel-framed buildings in the United States to use masonry not as structure, but as a curtain wall (as modern-designed skyscrapers do). Initially, trains arrived via elevated tracks built abov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Broadway Limited
The ''Broadway Limited'' was a passenger train operated by the Pennsylvania Railroad (PRR) between New York City and Chicago. It operated from 1912 to 1995. It was the Pennsylvania's premier train, competing directly with the New York Central Railroad's '' 20th Century Limited''. The ''Broadway Limited'' continued operating after the formation of Penn Central (PC) in February 1968, one of the few long-distance trains to do so. PC conveyed the train to Amtrak in 1971, who operated it until 1995. The train's name referred not to Broadway in Manhattan, but rather to the "broad way" of PRR's four-track right-of-way along the majority of its route. History Pennsylvania Railroad The ''Pennsylvania Special'' was one of nine express trains the Pennsylvania Railroad (PRR) operated between New York City and Chicago. On November 14, 1912, PRR renamed it the ''Broadway Limited'', to avoid confusion with the similarly-named ''Pennsylvania Limited''. The name, though spelled as "B ...

Reading Company
The Reading Company ( ) was a Philadelphia-headquartered railroad that provided passenger and commercial rail transport in eastern Pennsylvania and neighboring states that operated from 1924 until its 1976 acquisition by Conrail. Commonly called the Reading Railroad, and logotyped as Reading Lines, the Reading Company was a railroad holding company for the majority of its existence and was a single railroad during its later years. It operated service as Reading Railway System and was a successor to the Philadelphia and Reading Railway Company, founded in 1833. Until the decline in anthracite loadings in the Coal Region after World War II, it was one of the most prosperous corporations in the United States. Competition with the modern trucking industry that used the interstate highway system for short-distance transportation of goods, also known as short hauls, compounded the company's problems, forcing it into bankruptcy in 1971. Its railroad operations were merged into Conrail i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junction Railroad (Philadelphia)
The Junction Railroad was a railroad created in 1860 to connect lines west of downtown Philadelphia, Pennsylvania, and allow north-south traffic through the metropolitan area for the first time. The railroad consisted of 3.56 miles of double track and 5.3 miles of sidings. It owned no locomotives or rolling stock. The line connected the Philadelphia and Reading Rail Road line at the west end of the Columbia Bridge over the Schuylkill River, crossed the Pennsylvania Railroad line, ran parallel to Market Street, and turned south to connect with the Philadelphia, Wilmington and Baltimore Railroad at Gray's Ferry. It came under Pennsylvania Railroad control in 1881, and was eliminated by merger in 1908.
