A geographic coordinate system is a coordinate system that enables every location on Earth to be specified by a set of numbers, letters or symbols. The coordinates are often chosen such that one of the numbers represents a vertical position and two or three of the numbers represent a horizontal position; alternatively, a geographic position may be expressed in a combined three-dimensional Cartesian vector. A common choice of coordinates is latitude, longitude and elevation. To specify a location on a plane requires a map projection.
The 29th Street Yard (also known as Jackie Joyner-Kersee Yard) is a rail yard for the St. Louis MetroLink light rail system in Greater St. Louis.
A rail yard, railway yard or railroad yard is a complex series of railroad tracks for storing, sorting, or loading and unloading, railroad cars and locomotives. Railroad yards have many tracks in parallel for keeping rolling stock stored off the mainline, so that they do not obstruct the flow of traffic. Railroad cars are moved around by specially designed yard switchers, a type of locomotive. Cars in a railroad yard may be sorted by numerous categories, including railroad company, loaded or unloaded, destination, car type, or whether they need repairs. Railroad yards are normally built where there is a need to store cars while they are not being loaded or unloaded, or are waiting to be assembled into trains. Large yards may have a tower to control operations.
Light rail, light rail transit (LRT), or fast tram is a form of urban rail transit using rolling stock similar to a tramway, but operating at a higher capacity, and often on an exclusive right-of-way.
Greater St. Louis is a bi-state metropolitan area that completely surrounds and includes the independent city of St. Louis. It includes parts of both the U.S. states of Missouri and Illinois. The city core is on the Mississippi Riverfront on the border with Illinois in the geographic center of the metro area. The Mississippi River bisects the metro area in half geographically between Illinois and Missouri; however, the Missouri half is much more populous. St. Louis is the largest metro area in Missouri and the second largest in Illinois. St. Louis County is independent of the City of St. Louis and their two populations are generally tabulated separately.
The yard sits east of East St. Louis, Illinois. It is one of two MetroLink railyards that maintain the SD-400s and the SD-460s in Greater St. Louis. It opened in 2001 with the St. Clair County Extension. On October 27, 2009, Metro opened a new paint booth facility.
East St. Louis is a city in St. Clair and Madison counties in southwestern Illinois, United States. It is located across the Mississippi River from St. Louis, Missouri, in what is defined as the Metro-East region of Southern Illinois. Once a bustling industrial center, like many cities in the Rust Belt, East St. Louis has been severely affected by loss of jobs due to industrial restructuring during the second half of the 20th century. In 1950, East St. Louis was the fourth-largest city in Illinois when its population peaked at 82,366. As of the 2010 census, the city had a population of 27,006, less than one-third of the 1950 census.
