Green Line (CTA)
The Green Line is a rapid transit line on the Chicago Transit Authority's "L" system. It is a completely elevated route in the "L" system; all other routes may have various combinations of elevated, subway, street level (at grade), or freeway median sections. The Green Line utilizes the system's oldest segments, dating back to 1892, extending with 30 stops between Oak Park/ Forest Park (Harlem/Lake) and Chicago's West Side, to the Loop, and then to the South Side neighborhoods of West Englewood (Ashland/63rd) and Woodlawn (Cottage Grove/63rd). As of 2021, approximately 15,000 passengers board this line each weekday. Route Lake Street Elevated Beginning at the yard and inspection facilities in Forest Park, the Green Line runs east through Oak Park towards the city on an embankment adjacent to Metra's Union Pacific/West Line tracks from the Harlem Avenue terminal, on the border of Oak Park and Forest Park, to a point just west of Laramie Avenue.

51st Station
51st is a station on the Chicago Transit Authority's "L" system, located in Chicago, Illinois and serving the Green Line. It is situated at 319 E 51st Street, three blocks east of State Street. It opened on August 28, 1892. History 51st was built in 1892 when the South Side Elevated Railroad extended its line southward to serve the World's Columbian Exposition. The original station was designed by Myron H. Church and was a brick building with some elements of the Queen Anne style and a half-cone bay. The platforms at 51st were constructed like all other South Side Elevated Railroad platforms and consisted of wooden platforms with a tin canopy. When the A/B skip-stop system was introduced in 1949, 51st became an AB station. Because Garfield and 58th were B and A stations respectively, 51st became the transfer point between the Englewood (A) and Jackson Park (B) branches of the South Side Elevated. It served as the transfer point until 1982, when Garfield became an AB stati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct Current
Direct current (DC) is one-directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current. The abbreviations ''AC'' and ''DC'' are often used to mean simply ''alternating'' and ''direct'', as when they modify ''current'' or '' voltage''. Direct current may be converted from an alternating current supply by use of a rectifier, which contains electronic elements (usually) or electromechanical elements (historically) that allow current to flow only in one direction. Direct current may be converted into alternating current via an inverter. Direct current has many uses, from the charging of batteries to large power ...

Union Pacific
The Union Pacific Railroad , legally Union Pacific Railroad Company and often called simply Union Pacific, is a freight-hauling railroad that operates 8,300 locomotives over routes in 23 U.S. states west of Chicago and New Orleans. Union Pacific is the second largest railroad in the United States after BNSF, with which it shares a duopoly on transcontinental freight rail lines in the Western, Midwestern and Southern United States. Founded in 1862, the original Union Pacific Rail Road was part of the first transcontinental railroad project, later known as the Overland Route. Over the next century, UP absorbed the Missouri Pacific Railroad, the Chicago and North Western Transportation Company, the Western Pacific Railroad, the Missouri–Kansas–Texas Railroad and the Chicago, Rock Island and Pacific Railroad. In 1996, the Union Pacific merged with Southern Pacific Transportation Company, itself a giant system that was absorbed by the Denver and Rio Grande Western Rai ...

Belt Railway Of Chicago
The Belt Railway Company of Chicago , headquartered in Bedford Park, IL, is the largest switching terminal railroad in the United States. It is co-owned by six Class I railroads — BNSF Railway, Canadian National Railway, Canadian Pacific Railway (the BRC's north-south main line's northern terminus is, like the Indiana Harbor Belt, the Milwaukee District West Line in Chicago's Cragin neighborhood), CSX Transportation, Norfolk Southern Railway, and Union Pacific Railroad — each of which uses the switching and interchange facilities of the BRC. Owner lines and other railroads bring their trains to the Belt Railway to be separated, classified, and re-blocked into new trains for departure.

Union Pacific/West Line
The Union Pacific West Line (UP-W) is a Metra commuter rail line operated by Union Pacific Railroad in Chicago, Illinois and its western suburbs. Metra does not refer to its lines by particular colors, but the timetable accents for the Union Pacific West line are " Kate Shelley Rose" pink, honoring an Iowa woman who saved a Chicago & North Western Railway train from disaster in 1881. Green and yellow were already selected for the Union Pacific North Line and Union Pacific Northwest Line, respectively, so pink was chosen for this line. Therefore, the UP-W is the only Metra line that uses a color to honor a person instead of a fallen flag railroad. All Metra trains on this line terminated at until 2006, when the line was extended to its present terminus in . The line runs as part of the Union Pacific Railroad's Geneva Subdivision (ex-C&NW line to Clinton, Iowa.) The line was once known as the Chicago & Northwestern/West Line until UP took over the C&NW in 1995. The line runs from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

West Englewood, Chicago
West Englewood, one of the 77 community areas, is on the southwest side of Chicago, Illinois. At one time it was known as South Lynne. The boundaries of West Englewood are Garfield Blvd to the north, Racine Ave to the east, the CSX and Norfolk Southern RR tracks to the west, and the Belt Railway of Chicago to the south.
