Washington Metro in the context of "Potomac Yard station"

Arlington County, or simply Arlington, is a county in the U.S. state of Virginia. The county, which is located in the Washington metropolitan area and the broader Northern Virginia region, is positioned directly across from Washington, D.C., the national capital, on the southwestern bank of the Potomac River. The smallest self-governing county in the United States by area, Arlington County has both suburban and urbanized districts. Its urbanized districts are located in proximity to several Washington Metro stations and lines. Its seat of government is located in the Court House neighborhood, which hosts many of its administrative offices and county courthouse.

Originally part of the Nacotchtank tribe's territory prior to the establishment of the Colony of Virginia in 1606, English colonists began settling in Arlington by the 1670s; the area was eventually designated as part of Fairfax County in 1742. The colonial-era economy was mostly based in tobacco agriculture operated with enslaved labor and indentured servants on large plantations. Following the end of the Revolutionary War, Arlington's planters and yeoman farmers transitioned to other crops. Virginia ceded present-day Arlington to help form the District of Columbia, and from 1801 the area was known as Alexandria County; it was eventually retroceded back to Virginia in 1847 as a result of pressure from Alexandria, which was the county's primary commercial center.

Ballston Quarter is one of the first major suburban shopping centers built in the Washington metropolitan area. It opened in 1951 as Parkington Shopping Center and was the nation's first shopping center built around a multi-story parking garage. It is located at the intersection of Glebe Road and Wilson Boulevard in the Ballston neighborhood of Arlington County, Virginia, two blocks from Ballston–MU station on the Washington Metro's Orange and Silver lines. It was remodeled as Ballston Common Mall in 1986 and again in 2019 as Ballston Quarter.

Court House, also known as Courthouse, is a neighborhood in northern Arlington County, Virginia that serves as Arlington's seat of government. It is generally bounded by Arlington Boulevard, N Rhodes Street, Courthouse Road, Key Boulevard, and N Danville Street, and is located along an urban corridor that follows the Orange and Silver Metro lines.

The site of Fort Woodbury during the Civil War, Court House began in the late 19th century as a small community that surrounded Arlington County's first courthouse built outside of Alexandria, Virginia. Population growth in Arlington in the first half of the 20th century prompted greater residential and commercial development, which was further spurred by the opening of the Court House Metro station in 1979. Court House, like other neighborhoods in the Rosslyn-Ballston corridor, has since become mixed-use and transit-oriented.

The Chicago "L" (short for "elevated") is the rapid transit system serving the city of Chicago and some of its surrounding suburbs in the U.S. state of Illinois. Operated by the Chicago Transit Authority (CTA), it is the fourth-largest rapid transit system in the United States in terms of total route length, at 102.8 miles (165.4 km) long as of 2014, and the third-busiest rapid transit system in the United States after the New York City Subway and the Washington Metro. As of January 2024, the "L" had 1,480 rail cars operating across eight different routes on 224.1 miles of track. CTA trains make about 1,888 trips each day servicing 146 train stations. In 2024, the system had 127,463,400 rides, or about 454,300 per weekday in the third quarter of 2025.

The "L" provides 24-hour service on the Red and Blue Lines, making Chicago, New York City, and Copenhagen the only three cities in the world to offer 24-hour train service on some of their lines throughout their respective city limits. The oldest sections of the Chicago "L" started operations in 1892, making it the second-oldest rapid transit system in the Americas, after New York City's elevated lines. The "L" gained its name from "el" because large parts of the system run on elevated track. Portions of the network are in subway tunnels, at grade level, or in open cuts.

The Eastern Market is a public market in the Capitol Hill neighborhood of Washington, D.C., housed in a 19th-century brick building. Eastern Market was listed on the National Register of Historic Places in 1971. It is located on 7th Street, S.E., a few blocks east of the U.S. Capitol between North Carolina Avenue SE and C Street SE. Badly damaged by an early-morning fire in 2007, the market building reopened in the summer of 2009 following an extensive renovation.

Eastern Market also marks a smaller community within the Capitol Hill neighborhood by serving as an anchor point for other nearby stores and restaurants. It is served by the nearby Washington Metro Eastern Market (station) on the Blue, Orange, and Silver Lines.

Maryland Route 214 (MD 214) is a state highway in the U.S. state of Maryland. Known for most of its length as Central Avenue, the highway runs 24.97 miles (40.19 km) from Southern Avenue and East Capitol Street at the District of Columbia boundary in Capitol Heights east to Beverley Beach. MD 214 connects the central Prince George's County suburbs of Capitol Heights, Seat Pleasant, Largo, and Bowie with the southern Anne Arundel County communities of Davidsonville and Edgewater and several beach villages along the Chesapeake Bay. The highway connects Interstate 95 (I-95)/I-495 (Capital Beltway) to Northwest Stadium, Six Flags America, and several stations of the Washington Metro's Blue and Silver lines, which the route parallels between Capitol Heights and Largo.

MD 214 was constructed as part of three state highways. MD 214 proper was constructed in the mid-1910s from Washington to Largo and extended east to what is now U.S. Route 301 (US 301) through the 1920s. MD 254 was built from MD 2 in Edgewater west to Davidsonville in the early to mid-1920s. MD 253 was constructed from the modern end of the highway southeast to Beverley Beach between the mid-1920s and early 1930s. The gap between Bowie and Davidsonville was filled in the mid-1930s; MD 214 was extended east across a new Patuxent River bridge and took over MD 254's route to Edgewater. In the late 1940s, MD 214 was relocated through Edgewater and extended along most of MD 253 to Beverley Beach. The state highway was widened in Prince George's County in the 1930s and again in the 1950s, and from US 301 to MD 2 in the 1940s and again in the 1950s. MD 214 was expanded to a divided highway at US 301 in the late 1950s, at its interchange with the Capital Beltway in the mid-1960s, and when it bypassed Capitol Heights in the late 1960s. The two-lane gaps between those three segments were filled in the 1980s and 1990s.

Federal Triangle is a triangular area in Washington, D.C., formed by 15th Street NW, Constitution Avenue NW, Pennsylvania Avenue NW, and E Street NW. Federal Triangle is occupied by 10 large city and federal office buildings, all of which are part of the Pennsylvania Avenue National Historic Site. Seven of the buildings in Federal Triangle were built by the U.S. federal government in the early and mid-1930s as part of a coordinated construction plan that has been called "one of the greatest building projects ever undertaken". Two buildings predating this coordinated effort were incorporated into Federal Triangle, and one was constructed in the 1990s.

Federal Triangle station is the Washington Metro station serving Federal Triangle and its immediately surrounding areas.

A crowd is a group of people that have gathered for a common purpose or intent. Examples are a demonstration, a sports event, or a looting (classified in sociology as an acting crowd). A crowd may also simply be made up of many people going about their business in a busy area.

The term "the crowd" may sometimes refer to the lower orders of people in general.
