Service on Line 2 has evolved over time. From October 2001 to March 2015, trains operated every 15 minutes on an {{convert|8|km|mi|0|adj=on}} route between [[Bayview station (Ottawa)|Bayview]] and [[Greenboro station|Greenboro]] using three-module [[Bombardier Talent]] trains. In March 2015, the line switched to two-module [[Alstom LINT]] trains, with service frequency improving to every 12 minutes.

May 2020 marked the shutdown of the line for the Stage 2 expansion project.<ref name="update-feb-2024" /> Originally expected to be completed by September 2022, service resumed on January 6, 2025.<ref name=":4" /> The expanded {{convert|19|km|mi|0|adj=on}} line now extends to [[Limebank station|Limebank]], with trains running every 12 minutes using either four-module [[Stadler FLIRT]] trains or coupled pairs of two-module Alstom LINT trains.

==History==
===Pilot project===
<!--Other articles link to this section name. Thus, if you change this name, you must code an {{anchor}} for the old section name to avoid broken links.-->
The Trillium Line was introduced on October 15, 2001, as a pilot project to provide an alternative to the [[Transitway (Ottawa)|Transitway]] [[bus rapid transit]] on which Ottawa had long depended exclusively for its high-grade transit service. The single-track line operated with five stations and a single passing loop at [[Carleton station]].

As a pilot project, the Trillium Line system was built at the cost of {{CAD|21{{nbsp}}million|link=yes}}, relatively little compared with the hundreds of millions of dollars usually required to build a new transit line. It runs on an existing [[Canadian Pacific Railway]] track (Ellwood and [[Prescott, Ontario|Prescott]] subdivisions of [[Bytown and Prescott Railway]]<ref name="NiagaraRails">{{cite web|url=http://www.niagararails.com/cgi-bin/img.cgi?/maps/otawatrm.gif|title=Ottawa Railways|last=Duncan|first=Paul|work=NiagaraRails.com|format=GIF|access-date=January 12, 2009}}</ref>), so the only construction work necessary was to build the stations themselves and the passing tracks necessary to allow trains to operate in both directions. The track is shared with [[Ottawa Central Railway|Ottawa Central]] freight trains south of [[Walkley Yard]], which occasionally serve the [[National Research Council of Canada]]'s Automotive and Surface Transportation Research Centre.

From 2001 until 2015,<ref name="2015-Launch" /> the system used three diesel-powered [[Bombardier Transportation|Bombardier]] [[Talent (train)|Talent BR643]] [[low-floor]] [[diesel multiple unit]] trains. It was, however, described as "light rail", partly because plans called for it to be extended into Ottawa's downtown as a tramway-like service, and partly because the Talent vehicles, though designed for mainline railways in Europe, are much smaller and lighter than most mainline trains in North America, and do not meet the [[Association of American Railroads#Functions|Association of American Railroads']] standards for [[Buff strength|crash strength]]. Ottawa is also authorized to run trains with only a single operator and no other crew, something rare on mainline railways in North America.

Until late 2014, the official name of the diesel-powered, north–south line was "O-Train". After construction started on a second, east–west urban rail line (the [[Line 1 (O-Train)|Confederation Line]]), the O-Train name was applied to the entire system, and the north–south line was renamed the "Trillium Line".<ref>{{cite news|url=http://www.cbc.ca/news/canada/ottawa/o-train-name-approved-for-ottawa-light-rail-system-1.2769049|title=O-Train name approved for Ottawa light rail system|date=September 17, 2014|newspaper=[[CBC News Network]]|access-date=December 29, 2014|archive-url=https://web.archive.org/web/20141007113656/http://www.cbc.ca/news/canada/ottawa/o-train-name-approved-for-ottawa-light-rail-system-1.2769049|archive-date=October 7, 2014|url-status=live}}</ref>

====Original service====
[[File:ON OC-Tr 20050728-145844 RameTalent DesserteUrbaine.jpg|thumb|left|From 2001 to 2015, service was operated by two [[Bombardier Talent]] trains]]
[[File:Carletonstation.jpg|thumb|left|[[Carleton station|Carleton]] was the only location with two tracks during the pilot service. Note [[Gap filler|retractable platform extenders]] at solid yellow markings.]]
[[File:OttawaO-TrainInterior.jpg|thumb|left|Interior of the Bombardier Talent carriages (2001–2015)]]
Ticketing on Line 2 originally worked entirely on a proof-of-payment basis; there were no ticket barriers or [[Turnstile|turnstiles]], and the driver did not check fares. Occasionally, OC Transpo Special Constables or other employees prompted passengers for proof-of-payment. Tickets can be purchased from a vending machine on the platform, and certain bus passes are also valid for Line 2. Line 2 tickets were exchanged for bus transfers upon boarding a bus. Although bus transfers can be used to board the O-Train, prepaid bus tickets cannot.

The European trains were narrower than the North American standard. In order to enable night-time use of the line by standard-width freight services, [[Gap filler|retractable platform extenders]] were mounted at each station other than Bayview (which is constructed on its own private rail spur). Passengers gain access to Line 2 on these extenders. When a freight train needs to pass through a station, the extenders are retracted, allowing the wider train to pass through.

The 15-minute headway combined with a travel time of 12 minutes end-to-end<ref>{{cite web|url=http://www.octranspo.com:80/maps_menue.htm|title=O-Train Schedule September 2003|publisher=octranspo.com|access-date=August 7, 2010|archive-url=https://web.archive.org/web/20040401225004/http://www.octranspo.com:80/maps_menue.htm|archive-date=1 April 2004|url-status=live}}</ref> made it possible to run the line with a fleet of just three trains (of which only two were in service at any given time) and a single track, apart from passing sidings at [[Carleton station]].

The Trillium Line hit the 1-millionth rider mark on May 29, 2002, the 5-millionth mark on January 21, 2005, and the 10-millionth in late 2010.<ref>{{cite web|url=http://www.octranspo.com/routes/odometer_1_mil_km|title=OC Transpo - Odometer passes 1 Millionth KM!|publisher=octranspo.com|access-date=August 7, 2010|archive-url=https://web.archive.org/web/20190119121137/http://www.octranspo.com/routes/odometer_1_mil_km|archive-date=January 19, 2019|url-status=live}}</ref> In mid-2011, the Trillium Line carried an average of approximately 12,000 riders each day.<ref name="24may" />

====Awards====
In June 2002, the O-Train Light Rail Transit project received the [[Canadian Urban Transit Association]]’s Corporate Innovation Award.<ref name="O-Train Awards">{{cite web|url=http://www.tc.gc.ca/eng/programs/environment-utsp-otrainlightrailproject-973.htm|title=O-Train Light Rail Project|access-date=April 5, 2011|archive-url=https://web.archive.org/web/20110123114358/http://www.tc.gc.ca/eng/programs/environment-utsp-otrainlightrailproject-973.htm|archive-date=January 23, 2011|url-status=live}}</ref>

On January 16, 2003, the Ontario chapter of the [[American Public Works Association]] (APWA) presented the City of Ottawa, [[Canadian Pacific Railway]] and [[Morrison Hershfield]] with the APWA Public Works Project of the Year award in the transportation category. This award was established to highlight excellence in the management and administration of public works projects by recognizing the alliance between the managing agency, the consultant and the contractors who, working together, complete public works projects.<ref name="O-Train Award">{{cite web|url=http://www.acec.ca/en/memberfirms/paidprofile.asp?track=dp&itemid=1254|title=Acec.ca|access-date=April 5, 2011|archive-url=https://web.archive.org/web/20110724102819/http://www.acec.ca/en/memberfirms/paidprofile.asp?track=dp&itemid=1254|archive-date=July 24, 2011|url-status=dead}}</ref>

A third award the Trillium Line Light Rail transit project received was in May 2003, in the sustainable transportation category of the FCM-CH2M Hill Sustainable Community Awards.<ref name="O-Train Awards" />

====Criticism of pilot project====
The main complaints about the Trillium Line pilot have revolved around its placement and ridership levels. The Trillium Line's route was determined by existing railway tracks, rather than the parts of the city that needed public transport, which would have required new tracks to be laid. [[Carleton University]] students, however, have benefited from the connection to the busy [[Transitway (Ottawa)|Ottawa Transitway]] system.

The other criticism is that there is low ridership of the trains compared to some crowded bus lines, such as the 90–99 series routes. A fully loaded Line 2 train carries 285 passengers compared to 131 passengers for an [[articulated bus]].<ref>{{cite web|url= http://www.octranspo.com/contacts/press_releases/2001/010405_LowFloorBuses.htm|title= OC Transpo adds new low-floor articulated buses to its fleet|publisher= OC Transpo|date= April 5, 2001|access-date= January 12, 2009| archive-url = https://web.archive.org/web/20070929105859/http://www.octranspo.com/contacts/press_releases/2001/010405_LowFloorBuses.htm| archive-date = September 29, 2007}}</ref> The O-Train schedule is limited by track capacity.

====Early extension plans====
{{main|O-Train#Early extension plans}}
In July 2006, Ottawa City Council approved a north–south light rail expansion project. The project would have terminated diesel light rail service on the Trillium Line so as to reuse its right-of-way for a double-track, electric light rail line that would have extended west from the [[University of Ottawa]] to [[Bayview station (OC Transpo)|Bayview]] then south to [[Leitrim, Ontario|Leitrim]] and then west to [[Barrhaven]]. However, in December 2006, Ottawa City Council cancelled this project, thus leaving the diesel-powered Trillium Line unchanged.

===Service improvements===
[[File:J95729 OnOCTotrain 20160815-113119.58 Bayview.jpg|thumb|left|From 2015 to 2020, service was operated using single-unit Alstom LINT trains]]

On May 18, 2011, OC Transpo approved a $200,000 study to expand the Trillium Line. The $59-million proposal included the purchase of six new trainsets and track improvements that would decrease headways from 15 minutes to 8 minutes.<ref name="24may">{{cite web | url=https://www.railwaygazette.com/ottawa-o-train-extension-proposed/35945.article | title=Ottawa O-Train extension proposed | publisher=Railway Gazette International | date=May 24, 2011 | access-date=January 27, 2024 | archive-url=https://web.archive.org/web/20121002214005/http://www.railwaygazette.com/index.php?id=44&no_cache=1&tx_ttnews%5Btt_news%5D=13296&cHash=3d62410f22 | archive-date=October 2, 2012 | url-status=live }}</ref> The project would finally cost $60.3{{Nbsp}}million.<ref name="Improve-Service-2015">{{cite web |url=http://ottawa.ca/en/news/new-trains-improve-o-train-trillium-line-service |title=New Trains improve O-Train Trillium Line service |publisher=[[City of Ottawa]] |date=March 2, 2015 |access-date=July 31, 2015}}</ref>

In mid-2013, service on the Trillium Line was suspended for four months to implement service and track improvements such as new station platforms and two new passing tracks (near Brookfield and Gladstone).<ref name="Improve-Service-2015"/><ref name="2013-Upgrade">{{cite news |url=http://ottawa.ctvnews.ca/ottawa-s-o-train-back-on-track-1.1438643 |last=Hua |first=John |title=Ottawa's O-Train back on track |publisher=Bell Media |website=CTVNews.ca |date=September 3, 2013 |access-date=July 29, 2015 |archive-url=https://web.archive.org/web/20130906075120/http://ottawa.ctvnews.ca/ottawa-s-o-train-back-on-track-1.1438643 |archive-date=September 6, 2013 |url-status=live }}</ref> Upgrades were also made to the signal system, train controls, stations, tracks and train yard.

=== Derailment ===
On August 11, 2014, train C3 derailed while traveling northbound over the switch just south of Carleton station.<ref>{{Cite web|url=https://ottawacitizen.com/news/local-news/human-error-faulty-switch-caused-o-train-derailment|title=Human error, faulty switch caused O-Train derailment|work=Ottawa Citizen|last=Pearson|first=Matthew|date=August 22, 2014|access-date=February 16, 2019|archive-url=https://web.archive.org/web/20190217030258/https://ottawacitizen.com/news/local-news/human-error-faulty-switch-caused-o-train-derailment|archive-date=February 17, 2019|url-status=live}}</ref> The cause was determined to be a faulty spring switch that had not closed properly as well as the operator failing to follow regulations and physically inspect the switch after spotting a signal irregularity. No serious injuries occurred as a result of the derailment; however, train C3 received damage and was taken out of service. C3 was never repaired and never returned to service<ref name="sold" /> and as a result the line continued to operate with only two operational trains until the following March when the new Alstom LINT trains entered service. In June 2017, the spring switches at Carleton were replaced with powered switches.<ref>{{Cite web|url=https://shadqadri.com/2017/06/09/o-train-service-adjustment-carleton-spring-switchpreventative-maintenance/|title=O-Train Service Adjustment – Carleton Spring Switch/Preventative Maintenance|last=shadqadri|date=June 9, 2017|website=Shad Qadri|language=en|access-date=February 16, 2019|archive-url=https://web.archive.org/web/20190217142306/https://shadqadri.com/2017/06/09/o-train-service-adjustment-carleton-spring-switchpreventative-maintenance/|archive-date=February 17, 2019|url-status=live}}</ref>

=== Stage 2 expansion ===
As part of the city's Stage 2 LRT project, the Trillium Line was extended {{convert|11|km}} south from Greenboro to Limebank using a new grade-separated railway with four new stations at [[South Keys station|South Keys]], [[Leitrim station|Leitrim]], [[Bowesville station|Bowesville]] and [[Limebank station|Limebank]].

{{As of|2019||df=}}, ticket barriers are installed and operational in all Line 2 stations. They were initially installed in all stations except for Bayview in order to test the hardware and software of the fare gate system before it was installed in all thirteen stations on Line 1.

The Line 2 stations have large, bus-style sheltered waiting areas for passengers. All stations have level boarding platforms to allow for [[wheelchair]] [[accessibility|access]] and easier boarding for all passengers. Elevators are available at Greenboro (for Transitway riders), Dow's Lake (for Line 2 riders) and Bayview (for train transfers within the fare-paid zone).

These vehicles were manufactured in Switzerland before being transported to Canada for final assembly.<ref>{{Cite tech report|title=Report to: Council|page=52|date=February 22, 2019|url=https://www.stage2lrt.ca/wp-content/uploads/2019/02/Contract-Award-of-Ottawa%E2%80%99s-Stage-2-Light-Rail-Transit-Projects-and-Related-Matters.pdf|access-date=February 26, 2019|archive-url=https://web.archive.org/web/20190226172820/https://www.stage2lrt.ca/wp-content/uploads/2019/02/Contract-Award-of-Ottawa%E2%80%99s-Stage-2-Light-Rail-Transit-Projects-and-Related-Matters.pdf|archive-date=February 26, 2019|url-status=live}}</ref> The trains have a diesel-electric drive with the possibility of future electrification.

==Facilities==
Train sets are stored at the [[Walkley Yard]] located northeast of the Greenboro station. Before their retirement, the Bombardier Talent trainsets were maintained by [[Bombardier Transportation]] at the Walkley facilities. Bombardier continues to perform maintenance of the Line 2 fleet, which included standstill maintenance of the retired Bombardier Talent trains until March 8, 2018.<ref>{{Cite web|url=https://www.govdeals.com/index.cfm?fa=Main.Item&itemid=97&acctid=6620|title=Lot of Three (3) 1999 Bombardier Talent Trainsets and Parts - govdeals.com|website=www.govdeals.com|language=en|access-date=February 9, 2019|archive-url=https://web.archive.org/web/20190201013324/https://www.govdeals.com/index.cfm?fa=Main.Item&itemid=97&acctid=6620|archive-date=February 1, 2019|url-status=live}}</ref> The Walkley Yard was built in 1955 by the [[National Capital Commission]] for the [[Canadian National Railways]] and later sold to the [[Canadian Pacific Railway]]. The yard has enclosed buildings for repairs and outdoor storage tracks.

As part of the Stage 2 project, a new maintenance facility was built adjacent and to the west of the old facilities.<ref>{{Cite web|url=https://www.stage2lrt.ca/wp-content/uploads/2017/02/Appendix7.pdf|title=Relocated Walkley Yard MSF, West of Albion Road|date=January 17, 2016|access-date=February 22, 2019|archive-url=https://web.archive.org/web/20190223020424/https://www.stage2lrt.ca/wp-content/uploads/2017/02/Appendix7.pdf|archive-date=February 23, 2019|url-status=live}}</ref> The construction of the new yard facilities began in 2019.<ref>{{Cite web|url=http://ottwatch.ca/meetings/file/627775#page=12|title=Transit Services 2020 Business Plan|date=February 19, 2019|website=ottwatch.ca|page=12|access-date=February 23, 2020}}</ref>
