Editing Line 1 Yonge–University (section)

== Name ==
The line's name has been changed as it has been extended. Following its opening between Union Station and Eglinton Avenue along Yonge Street in 1954, it was called "the subway" (Yonge subway is its [[retronym]]).<ref>{{Cite web |date=November 23, 2017 |title=Canada's First Subway: Open for Business |url=https://www.toronto.ca/explore-enjoy/history-art-culture/online-exhibits/web-exhibits/web-exhibits-transportation/canadas-first-subway/canadas-first-subway-open-for-business/ |access-date=May 2, 2023 |website=City of Toronto |language=en-CA |archive-date=May 2, 2023 |archive-url=https://web.archive.org/web/20230502081716/https://www.toronto.ca/explore-enjoy/history-art-culture/online-exhibits/web-exhibits/web-exhibits-transportation/canadas-first-subway/canadas-first-subway-open-for-business/ |url-status=live }}</ref> In 1963, it was extended along University Avenue to St. George station and renamed the "Yonge–University Line".<ref>{{Cite web |date=June 29, 2021 |title=Bloor-Danforth-University Subway – University Subway |url=https://www.toronto.ca/explore-enjoy/history-art-culture/online-exhibits/web-exhibits/web-exhibits-transportation/the-ttc-100-years-of-moving-toronto/bloor-danforth-university-subway-university-subway/ |access-date=May 2, 2023 |website=City of Toronto |language=en-CA |archive-date=May 2, 2023 |archive-url=https://web.archive.org/web/20230502081718/https://www.toronto.ca/explore-enjoy/history-art-culture/online-exhibits/web-exhibits/web-exhibits-transportation/the-ttc-100-years-of-moving-toronto/bloor-danforth-university-subway-university-subway/ |url-status=live }}</ref> Briefly in 1966, the Yonge–University subway ran in two branches: one west along Bloor to [[Keele station]] (Yonge–University–Bloor), the other east along Bloor and Danforth to [[Woodbine station]] (Yonge–University–Danforth) via Bay Lower station.<ref>{{Cite web |last=Zerbisias |first=Antonia |date=July 22, 2013 |title=Invisible Toronto: from the bees' home above to the shuttered station below |url=https://www.thestar.com/news/gta/2013/07/22/invisible_toronto_from_the_bees_home_above_to_the_shuttered_station_below.html |access-date=September 19, 2017 |work=[[Toronto Star]] |archive-date=September 20, 2017 |archive-url=https://web.archive.org/web/20170920044448/https://www.thestar.com/news/gta/2013/07/22/invisible_toronto_from_the_bees_home_above_to_the_shuttered_station_below.html |url-status=live }}</ref>

In 1978, the "Spadina" section was opened and the line became the "Yonge–University–Spadina Line" (YUS).<ref name=":2">{{Cite web |date=June 29, 2021 |title=Spadina Subway |url=https://www.toronto.ca/explore-enjoy/history-art-culture/online-exhibits/web-exhibits/web-exhibits-transportation/the-ttc-100-years-of-moving-toronto/spadina-subway/ |access-date=May 2, 2023 |website=City of Toronto |language=en-CA |archive-date=May 2, 2023 |archive-url=https://web.archive.org/web/20230502081720/https://www.toronto.ca/explore-enjoy/history-art-culture/online-exhibits/web-exhibits/web-exhibits-transportation/the-ttc-100-years-of-moving-toronto/spadina-subway/ |url-status=live }}</ref> Although only two stations are on Spadina Road, a larger portion of the line was originally intended to follow the planned Spadina Expressway, which was partially built as [[Allen Road]].<ref name=":2" /> The subway also had an additional internal route number: route 602.<ref>[[Toronto Transit Commission]], [http://transittoronto.ca/archives/reports/1991.pdf Scheduled Service Summary] {{Webarchive|url=https://web.archive.org/web/20200927034444/https://transittoronto.ca/archives/reports/1991.pdf |date=September 27, 2020 }}, Board Period Commencing Sunday, July 21, 1991</ref>

Unofficially, subway lines were already numbered, but in October 2013, the TTC announced plans to display line numbers publicly to help riders to navigate the system.<ref>{{cite web |url=https://toronto.citynews.ca/2013/10/23/ttc-considers-numbering-subway-lines/ |title=TTC considers numbering subway lines |date=October 23, 2013 |work=CityNews Toronto |access-date=October 23, 2013 |archive-date=October 25, 2013 |archive-url=https://web.archive.org/web/20131025072757/http://www.citynews.ca/2013/10/23/ttc-considers-numbering-subway-lines/ |url-status=live }}</ref> In March 2014, the line was officially numbered and renamed "Line 1 Yonge–University", with the Spadina part being dropped from the name. Announcements, documentation and rapid transit maps across the system now refer to the line as "Line 1" or "Line 1 Yonge–University".<ref>{{cite web |url=http://www3.ttc.ca/Subway/index.jsp |title=TTC Subway/RT |publisher=Toronto Transit Commission |access-date=February 17, 2012 |archive-date=March 23, 2016 |archive-url=https://web.archive.org/web/20160323101602/http://ttc.ca/Subway/index.jsp |url-status=dead }}</ref>
