An elevated railway (also known in Europe as overhead railway) is a form of rapid transit railway with the tracks built above street level on some form of viaduct or other steel, concrete or brick structure. The railway concerned may be constructed according to the standard gauge, narrow gauge, light rail, monorail or suspension railway system. Elevated railways are usually used in urban areas where otherwise there would be a large number of level crossings.
The earliest example of an elevated railway was the London and Greenwich Railway which was built on a brick viaduct of 878 arches between 1836 and 1838. Various other lines were proposed for London during the 1840s but were never implemented.
From the late 1860s elevated railways became popular in US cities. The New York West Side and Yonkers Patent Railway operated with cable cars from 1868 to 1870, but thereafter was locomotive hauled. This was followed by the Manhattan Railway in 1875, the Boston Elevated Railway (1887-), and the South Side Elevated Railroad, Chicago (1892-). The Berlin Stadtbahn (1882) is also principally on elevated track.
Cameron Jibril Thomaz (born September 8, 1987), better known by the stage name Wiz Khalifa, is an American rapper. He released his debut album, Show and Prove, in 2006, and signed to Warner Bros. Records in 2007. His Eurodance-influenced single, "Say Yeah", received urban radio airplay, charting on the Rhythmic Top 40 and Hot Rap Tracks charts in 2008. Khalifa parted with Warner Bros. and released his second album, Deal or No Deal, in November 2009. He released the mixtape Kush and Orange Juice as a free download in April 2010; he then signed with Atlantic Records. He is also well known for his debut single for Atlantic, "Black and Yellow", which peaked at number 1 on the Billboard Hot 100. His debut album for the label, Rolling Papers, was released on March 29, 2011.
Khalifa was born on September 8, 1987 to a mother and a father serving in the military. His parents divorced when Khalifa was about three years old. His parents' military service caused him to move regularly: Khalifa lived in Germany, the United Kingdom, and Japan before settling in Pittsburgh where he attended Taylor Allderdice High School.
