Editing Line 4 Sheppard (section)

===Rolling stock===
From its opening in November 2002 to May 2016, the line was operated solely with four-car [[T series (Toronto subway)|T1]] subway trains, with two staff members operating the trains – one driver and one guard who operated the doors. On May 30, 2016, new four-car [[Toronto Rocket]] (TR) subway trains were introduced on this line. They replaced the older T1 subway trains, which were moved to Line 2 Bloor–Danforth. The TRs are based on [[Bombardier Transportation]]'s [[Bombardier Movia|Movia]]<!--Don't bypass redirect per [[WP:NOTBROKEN]]-->-styled train sets and are the first TTC trains which have no separators between the cars. This allows passengers to walk freely from one end to the other, unlike Toronto's previous subway cars. The change to TR trains was necessary because Line 4 trains are based in [[Davisville Yard]], which is accessed via [[Line 1 Yonge–University]]. Line 1 was converted to operate using an [[automatic train control]] system, with the conversion finishing in September 2022.<ref name="TTC-2022-09-29">{{cite web |date=September 29, 2022 |title=TTC's Line 1 now running on an ATC signalling system |url=https://www.ttc.ca/news/2022/September/TTCs-Line-1-now-running-on-an-ATC-signalling-system |url-status=live |archive-url=https://web.archive.org/web/20220929194155/https://www.ttc.ca/news/2022/September/TTCs-Line-1-now-running-on-an-ATC-signalling-system |archive-date=September 29, 2022 |access-date=December 13, 2022 |publisher=[[Toronto Transit Commission]]}}</ref><ref>{{cite web |url=http://www.cbc.ca/news/canada/toronto/sheppard-subway-line-gets-new-toronto-rocket-trains-1.3607811 |title=Sheppard subway line gets new Toronto Rocket trains |work=CBC News |date=May 30, 2016 |access-date=May 1, 2018 |url-status=live |archive-url=https://web.archive.org/web/20171004152256/http://www.cbc.ca/news/canada/toronto/sheppard-subway-line-gets-new-toronto-rocket-trains-1.3607811 |archive-date=October 4, 2017}}</ref> From October 9, 2016, Line 4 has been served entirely by four-car TR trains, which are operated by one staff member who both drives the train and operates the doors, similar to the model that was in use on the former [[Line 3 Scarborough]].<ref>{{cite web |url=http://www.cp24.com/news/ttc-switching-to-single-operator-model-for-line-4-subway-as-of-oct-9-1.3091153 |title=TTC switching to single-operator model for Line 4 subway as of Oct. 9 |website=CP24 |last=Fox |first=Chris |date=September 27, 2016 |access-date=June 20, 2017 |archive-url=https://web.archive.org/web/20160927200936/http://www.cp24.com/news/ttc-switching-to-single-operator-model-for-line-4-subway-as-of-oct-9-1.3091153 |archive-date=September 27, 2016 |url-status=live}}</ref><ref>{{Cite web |last=Murno |first=Steve |date=November 10, 2022 |title=TTC Service Changes Effective November 20, 2022 (Updated) |url=https://stevemunro.ca/2022/11/10/ttc-service-changes-effective-november-20-2022/ |access-date=December 13, 2022 |website=Steve Munro |language=en |archive-date=December 14, 2022 |archive-url=https://web.archive.org/web/20221214010856/https://stevemunro.ca/2022/11/10/ttc-service-changes-effective-november-20-2022/ |url-status=live}}</ref>
