Editing IND Queens Boulevard Line (section)

====63rd Street changes====
As part of the construction of the  [[IND 63rd Street Line]] in the 1980s, it was proposed to reverse-signal the IND Queens Boulevard Line, to allow three of the line's four tracks to run in a single peak direction.<ref name="NYTimes-63St-QBLRevSig-1987">* {{cite news|last=Levine|first=Richard|date=February 7, 1987|title=M.T.A.

Beginning on March 23, 1997, due to construction on the connector between the IND 63rd Street Line and the IND Queens Boulevard Line, G trains terminated at [[Court Square (IND Crosstown Line)|Court Square]] on evenings, nights and weekends. On August 30, 1997, late night G service was permanently cut back from 179th Street to Court Square, being replaced with the F running local east of Queens Plaza, meaning that the G only ran along the Queens Boulevard Line on weekdays.<ref name="MTA-GLineReview-2013">{{cite web|url=http://web.mta.info/nyct/service/G_LineReview_7_10_13.pdf|title=Review of the G Line|date=July 10, 2013|website=[[Metropolitan Transportation Authority|mta.info]]|publisher=[[Metropolitan Transportation Authority]]|archive-url=https://web.archive.org/web/20150226002828/http://web.mta.info/nyct/service/G_LineReview_7_10_13.pdf|archive-date=February 26, 2015|url-status=live|access-date=August 2, 2015}}</ref><ref name="New York Daily News">{{Cite news|url=https://www.newspapers.com/clip/24160214/august_30_queens_boulevard_changes/|title=Starting August 30, there will be changes in late-night service along Queens Boulevard.|date=September 2, 1997|work=New York Daily News|access-date=September 30, 2018|archive-date=November 6, 2018|archive-url=https://web.archive.org/web/20181106004850/https://www.newspapers.com/clip/24160214/august_30_queens_boulevard_changes/|url-status=live}}</ref> On that date, E service began running local in [[Queens]] during late nights.<ref name="erictb.info">{{Cite web|url=http://www.erictb.info/linehistory.html|title=NYCT Line by Line History|last=Bolden|first=Eric|website=www.erictb.info|access-date=June 17, 2016|archive-date=March 4, 2016|archive-url=https://web.archive.org/web/20160304100921/http://www.erictb.info/linehistory.html|url-status=live}}</ref><ref name="New York Daily News" />

On December 16, 2001, the connection to the [[63rd Street Lines|IND 63rd Street Line]] (built along with the Archer Avenue subway) opened and F trains were rerouted into it, away from the 53rd Street tunnel. The new peak-hour {{NYCS|V}} train was created to replace the F via 53rd Street while running local on Queens Boulevard, requiring the truncation of the G to Court Square during weekdays.<ref name="MTA-FGLineReviews" /><ref name="BklynPaper-GTrainExt-April2012">* {{cite web|url=http://www.brooklynpaper.com/stories/35/15/dtg_gtrainhistory_2012_04_13_bk.html|title=History shows it's not the G train 'extension' — it's the G train renewal|last1=O'Neill|first1=Natalie|date=April 13, 2012|website=[[The Brooklyn Paper]]|access-date=August 2, 2015|archive-date=July 23, 2015|archive-url=https://web.archive.org/web/20150723013440/http://www.brooklynpaper.com/stories/35/15/dtg_gtrainhistory_2012_04_13_bk.html|url-status=live}}
