Editing Kitchener line (section)

===Infrastructure===
As a part of the [[History of GO Transit#GO TRIP|GO Transit Rail Improvement Program]], the [[West Toronto Diamond]] was grade separated. The Metrolinx Weston Subdivision, which carries the Kitchener Line as well as [[Union Pearson Express]] and [[Via Rail|Via]] trains, was lowered into a trench to pass under [[Canadian Pacific Railway|CP]]'s North Toronto Subdivision.<ref name="gradesep">{{cite web

The Georgetown South railway expansion project was initiated in 2009 with [[Metrolinx]] now as its proponent.<ref>{{cite web|url=http://www.metrolinx.com/Docs/News/Project_START_News_Release_Final_Dec_15.pdf|title=News Release - Metrolinx is new proponent of Georgetown Line|date=December 2009}}{{Dead link|date=August 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref>  The project represented a significant increase in railway capacity, with the former one- to two-track<ref>http://www.mapleleaftracks.com/Store/Free/Greater%20Toronto%20Area%20Documentation.pdf {{Bare URL PDF|date=March 2022}}</ref> railway being widened to 4 tracks within Toronto, with a total of 8 tracks where the Milton line and Barrie line share the corridor. All level crossings along the corridor were eliminated using railway or roadway underpasses.  The plan would allow for an increased frequency of trains on the route, increasing service from approximately 50 per day to about 300.<ref name="weston">{{cite web

They  preferred instead that the corridor be [[Railway electrification system|electrified]].<ref name="weston" /> The group has also requested more stations along the route.<ref name="weston" />

The Georgetown South project was later reduced in scope due to cost overruns: the corridor was expanded to three tracks, with the fourth track as well as the dedicated Barrie line tracks deferred to future projects. Construction on the Weston subdivision itself finished in 2015,<ref>{{Cite web | url=http://www.metrolinx.com/en/projectsandprograms/transitexpansionprojects/gts.aspx | title=Metrolinx Georgetown South Project | access-date=2019-10-19 | archive-date=2019-10-19 | archive-url=https://web.archive.org/web/20191019145323/http://www.metrolinx.com/en/projectsandprograms/transitexpansionprojects/gts.aspx | url-status=dead }}</ref> allowing Union Pearson Express to begin operating, while additional track work in the [[Union Station Rail Corridor]] continued into 2016.<ref>http://libraryarchives.metro.net/RMC/18-672-Whitbred/18-672-3-APPENDIX-A-RESUMES-METRO-SYSTEMS-PARTNERS.pdf#p46 {{Webarchive|url=https://web.archive.org/web/20191212065847/http://libraryarchives.metro.net/RMC/18-672-Whitbred/18-672-3-APPENDIX-A-RESUMES-METRO-SYSTEMS-PARTNERS.pdf#p46 |date=2019-12-12 }} {{Bare URL PDF|date=March 2022}}</ref>

In 2019, Metrolinx conducted a series of public forums on electrification of the Kitchener line from Georgetown to Kitchener, in a change from its earlier Regional Express Rail plan, which had called for continuation of diesel train service on the western portion of the line. Electrification plans reaffirmed overall Metrolinx goals of track bed and bridge improvements, quad-tracking sections of the line, and the addition of a station at Breslau.<ref>{{cite news |url=https://kitchener.ctvnews.ca/metrolinx-talks-go-train-electrification-in-kitchener-1.4702403 |title=Metrolinx talks GO train electrification in Kitchener |first=Spencer |last=Turcotte |date=25 November 2019 |publisher=[[CTV News]]}}</ref>
