The '''IRT Flushing Line''' is a [[rapid transit]] route of the [[New York City Subway|New York City Subway system]], named for its eastern terminal in [[Flushing, Queens]]. It is operated as part of the [[A Division (New York City Subway)|A Division]]. The [[Interborough Rapid Transit Company]] (IRT), a private operator, had constructed the section of the line from [[Flushing, Queens|Flushing]], [[Queens]], to [[Times Square]], [[Manhattan]] between 1915 and 1928. A [[7 Subway Extension|western extension]] was opened to [[Hudson Yards Redevelopment Project|Hudson Yards]] in western Manhattan in 2015, and the line now stretches from Flushing to [[Chelsea, Manhattan]]. It carries trains of the {{NYCS|7}} local service, as well as the express {{NYCS|7d|&lt;7&gt;}} during rush hours in the peak direction.<ref name="NYCS7">{{NYCS const|timetable|7}}</ref> It is the only currently operational IRT line to serve Queens.

It is shown in the color {{NYCS const|color|purple}} on station signs, the official subway map, and internal route maps in [[R188 (New York City Subway car)|R188]] cars. Before the line was opened all the way to Flushing in 1928, it was known as the '''Corona Line''' or '''Woodside and Corona Line'''. Prior to the discontinuation of [[Brooklyn–Manhattan Transit Corporation|BMT services]] in 1949, the portion of the IRT Flushing Line between [[Times Square (IRT Flushing Line)|Times Square]] and [[Queensboro Plaza (IRT Flushing Line)|Queensboro Plaza]] was known as the '''Queensboro Line'''. Since the mid-2010s, the line's signal system has been converted to an [[Signaling of the New York City Subway#Automation|automated system]].

The Flushing Line has various styles of architecture, which range from steel [[girder]] [[elevated railway|elevated structures]] to European-style concrete [[viaduct]]s. The underground stations have some unique designs as well. The designs include [[Hunters Point Avenue (IRT Flushing Line)|Hunters Point Avenue]], which is in an [[Italianate]] style; [[Grand Central–42nd Street (New York City Subway)|Grand Central–42nd Street]], which is a single round tube similar to a [[London Underground]] station; and [[34th Street–Hudson Yards station|34th Street–Hudson Yards]], which, with its deep vault and spacious interior, resembles a [[Washington Metro]] station.
