'''504 King''' ('''304 King''' during overnight periods) is an east–west [[Toronto streetcar system|Toronto streetcar route]] in [[Ontario]], Canada. It serves [[King Street (Toronto)|King Street]] in [[Downtown Toronto]] as well as [[Broadview Avenue]] on the east end and [[Roncesvalles Avenue]] on the west end of the line. The route consists of two overlapping branches: 504A between [[Line 2 Bloor–Danforth]]'s [[Dundas West station]] and [[Distillery Loop]], and 504B between [[Broadview station]]{{Snd}}also on Line 2{{Snd}}and [[Dufferin Gate Loop]]. The two branches overlap on King Street between Dufferin and Sumach streets, both passing [[St. Andrew station]] and [[King station (Toronto)|King station]] on subway [[Line 1 Yonge–University]].

In 2022, with almost 13.5 million annual boardings, 504 King was the busiest streetcar line in Toronto. (In 2019, prior to the [[Toronto Transit Commission incidents#COVID-19 pandemic|drop in ridership due to the COVID-19 pandemic]], there were almost 29.7 million annual boardings.)<ref name="TTC-annual-boardings">{{cite web |url=https://www.ttc.ca/transparency-and-accountability/transit-planning |title=Transit Planning{{snd}}Annual streetcar boardings by route |publisher=[[Toronto Transit Commission]] |date=2022 |accessdate=January 10, 2024 |archive-url=https://web.archive.org/web/20230922223103/https://www.ttc.ca/transparency-and-accountability/transit-planning | archive-date=September 22, 2023 |url-status=live}}</ref>

==Route==
The 504 King route operates as two overlapping branches:
* 504A King streetcars operate from [[Dundas West station]] to [[Distillery Loop and Cherry Street branch|Distillery Loop]], travelling south on Dundas Street West and Roncesvalles Avenue, east on King Street West and East, and south on Cherry Street to Distillery Loop.
* 504B King streetcars operate from [[Dufferin Gate Loop]] to [[Broadview station]], travelling north on Dufferin Street, east on King Street West and East, east on Queen Street East, and north on Broadview Avenue to Broadview station.

In the west, route 504A King starts at Dundas West station on [[Line 2 Bloor–Danforth]]. From there, the route goes a short distance south of [[Bloor Street]] along [[Dundas Street (Toronto)|Dundas Street West]] to Roncesvalles Avenue, where it continues farther south on [[Roncesvalles Avenue]], crossing Howard Park Avenue and route [[506 Carlton]]. 504A King passes the [[Roncesvalles Carhouse]] as it approaches [[Queen Street West]] and [[the Queensway]].<ref name="TTC-504-map">{{cite web |url=https://www.ttc.ca/routes-and-schedules#/504/0 |title=504 King – Map |publisher=[[Toronto Transit Commission]] |date=November 8, 2017 |access-date=December 7, 2017}}</ref>

South of Queen Street West and the Queensway, the route turns east along [[King Street (Toronto)|King Street]]. At [[Dufferin Street]], 504B streetcars from [[Dufferin Gate Loop]] merge with 504A streetcars to provide a combined service along King Street to Sumach Street. Continuing further east to [[Bathurst Street (Toronto)|Bathurst Street]], the 504 enters a [[transit mall]] where automobiles have restrictions so as not to impede streetcar service. Continuing eastward past [[Spadina Avenue]], the 504 route passes [[St. Andrew station]] at [[University Avenue (Toronto)|University Avenue]] and [[King station (Toronto)|King station]] at [[Yonge Street]], both on [[Line 1 Yonge–University]]. At [[Jarvis Street]], the transit mall ends and routes 504A and 504B continue to Sumach Street, where route 504A turns south on [[Cherry Street (Toronto)|Cherry Street]] to proceed to Distillery Loop. Route 504B continues on King Street, as the street bends northeast to merge with [[Queen Street East]], then crosses the [[Queen Street Viaduct]] and the [[Don River (Ontario)|Don River]] to arrive at [[Broadview Avenue]].<ref name="TTC-504-map" />

Route 504B turns north on Broadview Avenue. Continuing on Broadview Avenue, route 504B eventually crosses [[Danforth Avenue]] arriving at [[Broadview station]] on Line 2 Bloor–Danforth.<ref name="TTC-504-map" />

===King Street Transit Priority Corridor<span id="King Street transit mall"></span><span id="Transit mall"></span>===
{{main|King Street Transit Priority Corridor}}
Route 504 King passes through the King Street Transit Priority Corridor, a [[transit mall]] located between [[Bathurst Street (Toronto)|Bathurst Street]] and [[Jarvis Street]]. Within the mall, there are restrictions on road traffic to prevent the obstruction of transit vehicles. Trucks and cars may enter the traffic mall, but must leave at the next intersection by turning right – with a few exceptions; left turns within the transit mall are not allowed.<ref name="TheStar-2019-04-16">{{Cite web |url=https://www.thestar.com/news/city_hall/2019/04/16/torontos-king-streetcar-pilot-project-is-now-permanent.html |title=Toronto's King streetcar pilot project is now permanent |work=Toronto Star |date=April 16, 2019 |access-date=June 26, 2019}}</ref><ref name="TheStar-2017-07-06">{{Cite web |url=https://www.thestar.com/news/city_hall/2017/07/06/council-approves-king-st-pilot-to-prioritize-streetcars-but-bows-to-taxi-industry.html |title=Council approves King St. pilot to prioritize streetcars, but bows to taxi industry |work=Toronto Star |date=July 6, 2017 |access-date=June 26, 2019}}</ref>

[[File:RoncesvallesAvenueBumpout.JPG|thumb|Bumpout on Roncesvalles Avenue serving as both a streetcar loading platform as well as a bicycle lane]]
{{main|Roncesvalles Avenue#Streetcar stop bumpouts}}
Between 2009 and 2011,<ref name="TTC-2020-06-24" /> Roncesvalles Avenue was rebuilt to a new design, which included the addition of [[bike lane]]s and a widened sidewalk "[[Bus bulb|bumpout]]" at [[tram stop|stops]] to allow riders to board streetcars directly from the curb. In these sections, the bike lane gently rises from the main road to run on top of the {{notatypo|bumpout}}; when a streetcar is stopped at a bumpout, cyclists are required to stop and allow riders to board or alight from the vehicle.<ref name="RoncesvallesVillage">{{cite news |url=http://roncesvallesvillage.ca/2009/lanes-tracks-and-bikes-oh-my/ |title=Lanes, tracks and bikes |publisher=Roncesvalles Village BIA | access-date=May 12, 2015 | archive-url=https://web.archive.org/web/20150518094536/http://roncesvallesvillage.ca/2009/lanes-tracks-and-bikes-oh-my/ | archive-date=May 18, 2015}}</ref><ref name="SteveMunro2010-12-19">{{cite news |url=http://stevemunro.ca/2010/12/19/parliament-and-roncesvalles-track-work-starts-july-2010/ |title=Parliament and Roncesvalles 2010 Track Work |publisher=Steve Munro |first=Steve |last=Munro |author-link=Steve Munro |date=December 19, 2010 |access-date=December 19, 2010 }}</ref> However, the platform height at the bumpouts was incompatible with the accessibility ramp on the low-floor [[Flexity Outlook (Toronto streetcar)|Flexity Outlook streetcars]] that were introduced in 2018 on the 504 King route.

==History==
On July 1, 1923, as part of a reorganization of streetcar routes, the King streetcar route acquired its current U-shape. The west end of the line was at the Vincent Loop, located near the northeast corner of Dundas Street West and Bloor Street West, across the street from today's [[Dundas West station]]. The east end of the line was at the Erindale Loop, located at the northeast corner of Broadview Avenue and Erindale Avenue, on the north side of today's [[Broadview station]].<ref name="TT-4103">{{cite web |url=https://transit.toronto.on.ca/streetcar/4103.shtml |title=Route 504 – The King Streetcar |publisher=Transit Toronto |first=James |last=Bow |date=September 16, 2017 |access-date=December 7, 2017}}</ref>

From July 1, 1923, to July 13, 1951, some King streetcars provided rush-hour service along Bloor Street West between Dundas Street West and [[Jane Loop]]. The TTC ended this service due to declining ridership. Starting July 16, 1951, all King service turned back at Vincent Loop.<ref name="TTC-story" />{{rp|52,73–74}}

On January 8, 1939, PCC streetcars were introduced on the King route on Sundays, displacing Peter Witt streetcars.<ref name="TTC-story" />{{rp|42}} On September 24, 1940, PCCs replaced Peter Witt cars in base service.<ref name="TTC-story" />{{rp|43}}

On February 25, 1966, the Bloor–Danforth subway (today [[Line 2 Bloor–Danforth]]) opened, and Dundas West station replaced the Vincent Loop, and Broadview station replaced the Erindale Loop. Both new subway stations had, and still have, a streetcar loop within the fare-paid zone. Otherwise, the King streetcar route had changed little since 1923.<ref name="TT-4103" />

In 2006, the TTC briefly considered adding [[Coupler (railway)|couplers]] to streetcars to enable operation of streetcars in [[Multiple-unit train control|two or three units]], a common practice until the opening of the Bloor–Danforth subway; the expectation was that this would keep them from bunching and becoming stuck in traffic. This plan was rejected<ref name="TheStar-2006-04-15">{{cite news |url=https://transit.toronto.on.ca/archives/data/200604150905.shtml |title=All aboard for the King St. choo-choo |newspaper=[[Toronto Star]] |first=Kevin |last=McGran |date=April 15, 2006 |access-date=October 25, 2017}}</ref> in favour of ordering brand-new, longer [[Flexity Outlook (Toronto streetcar)|Flexity Outlook]] vehicles.

Starting June 19, 2016, a new route – [[514 Cherry]] – was created to supplement 504 King service on King Street between Dufferin and Sumach streets. The 514 route increased capacity along the King Street corridor to address the growing downtown ridership. It also addressed [[Toronto Transit Commission accessibility|accessibility concerns]] through its use of the [[low-floor tram|low-floor]] Flexity Outlook streetcars.<ref name="TTC-2016-03-26">{{Cite web |url=http://www.ttc.ca/About_the_TTC/Commission_reports_and_information/Commission_meetings/2016/March_23/Reports/Improved_Transit_Service_in_EastCentral_Downtown_514_Cherry_.pdf |title=Improved_Transit_Service_in_EastCentral_Downtown_514_Cherry_.pdf |date=March 23, 2016 |website=TTC |access-date=April 18, 2016 |archive-url=https://web.archive.org/web/20210803111710/http://www.ttc.ca/About_the_TTC/Commission_reports_and_information/Commission_meetings/2016/March_23/Reports/Improved_Transit_Service_in_EastCentral_Downtown_514_Cherry_.pdf | archive-date=August 3, 2021}}</ref>

From December 2, 2017, the TTC assigned a minimum of two Flexity Outlook streetcars on 504 King to handle weekday overcrowding, as the [[#Transit mall|King Street Pilot Project]] improved service performance and made the service more popular.<ref name="TheStar-2017-12-04">{{cite news |url=https://www.thestar.com/news/gta/transportation/2017/12/04/king-st-pilot-has-slashed-streetcar-travel-times-stats-show.html |title=King St. pilot project has slashed streetcar travel times, statistics show |newspaper=[[Toronto Star]] |first1=Tamar |last1=Harris |first2=Ben |last2=Spurr |date=December 4, 2017 |access-date=December 5, 2017}}</ref>

On January 2, 2018, [[Flexity Outlook (Toronto streetcar)|Flexity Outlook streetcars]] were introduced on the 504 King route.<ref name="TTC-Accessible" />

On October 7, 2018, 504 King was divided into two overlapping branches with two new termini (Dufferin Gate Loop and Distillery Loop) replacing the [[514 Cherry]] route, which was permanently cancelled on the same date. The 304 King Blue Night service remained unchanged.<ref name="TTC-2018-10-07">{{cite web |url=http://www.ttc.ca/Service_Advisories/504-514_route_change.jsp |title=The current section is Service Advisories 504 King and 514 Cherry route changes |publisher=[[Toronto Transit Commission]] |date=October 7, 2018 |access-date=October 7, 2018 |archive-url=https://web.archive.org/web/20180925025413/http://www.ttc.ca/Service_Advisories/504-514_route_change.jsp |archive-date=September 25, 2018}}</ref>

On May 9, 2021, the intersection of King Street, Queen Street, The Queensway and Roncesvalles Avenue (KQQR) closed due to various construction projects in the area such as track replacement, reconfiguration of the KQQR intersection, adjusting the height of streetcar loading platforms along Roncesvalles Avenue and upgrades to water, sewer and electrical infrastructure.

===Blue Night service===
From 1987 to 1992, the Blue Night Network included the 304 King route, which provided overnight service along the length of the 504 King daytime route. The 304 route was eliminated in February 1992, with the Broadview and Roncesvalles segments replaced by portions of other Blue Night bus routes; however, King Street remained unserviced directly until September 6, 2015, when the 304 King was restored as part of a $95-million investment from [[Toronto City Council]]. Currently, overnight service operate every 30 minutes between Broadview and Dundas West stations via Broadview Avenue, King Street, and Roncesvalles Avenue.<ref name="SteveMunro-2015-08-08">{{cite web |url=http://stevemunro.ca/2015/08/08/blue-night-service-expansion-fall-2015/ |title=Blue Night Service Expansion: Fall 2015 |first=Steve |last=Munro |author-link=Steve Munro |date=August 8, 2015 |access-date=March 28, 2016 |quote=All (night) services will operate on 30 minute headways...304 King (will provide) all night service on the 504 King route.}}</ref>
