Rapid transit line in Ottawa, Ontario

The Trillium Line , also called O Train Line 2 , is a diesel light rail transit (DLRT) service in Ottawa, Ontario, Canada, operated by OC Transpo. The line has been closed since May 2020 for service expansion. Part of the O Train light rail system, the line runs north–south for between Bayview and Greenboro. The line is a single track, with three passing sidings on dedicated rights of way shared with Ottawa Central freight trains south of Walkley Yard, which occasionally serve the National Research Council of Canada's Automotive and Surface Transportation Research Centre. Despite being a local public transit line, it is actually a federally regulated mainline railway and operated under the official name "Capital Railway", which appears on the trains in addition to the service's logo. All stations except have single platforms. Between 2013 and 2015, the line was upgraded and its fleet replaced, cutting wait times during peak periods from 15 minutes to 12 minutes.

Ticketing on the Trillium Line originally worked entirely on a proof of payment basis; there were no ticket barriers or 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 the Trillium Line. Trillium Line 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 are narrower than the North American standard. In order to enable night time use of the line by standard width freight services, retractable platform extenders are mounted at each station (other than Bayview which is constructed on its own private rail spur). Passengers gain access to the Trillium Line on these extenders. If the line is used for freight, the extenders are retracted allowing a wider train to pass through the station. The extender interface with the train has been refined over time, and cyclists and wheelchair users now have no trouble accessing the train. The service frequency of a train every fifteen minutes 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. In mid 2011, the Trillium Line carried an average of approximately 12,000 riders each day. 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. 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. The O Train schedule is limited by track capacity.

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 then south to Leitrim and then west to Barrhaven. However, in December 2006, Ottawa City Council cancelled this project, thus leaving the diesel powered Trillium Line unchanged.

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. The project would finally cost $60.3million. 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). Upgrades were also made to the signal system, train controls, stations, tracks and train yard. A new centralized traffic control system was installed to improve safety and efficiency. Although the changes were intended to improve frequency to eight minutes, the Trillium Line would ultimately operate at twelve minute frequency. After the completion of the Stage 2 project, the line was originally planned to continue operating using single car trains; however, because of the lower than intended frequency, the city was forced to adjust the Stage 2 plan to include longer trains and platforms to compensate.

On August 11, 2014, train C3 derailed while traveling northbound over the switch just south of Carleton station. 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

As part of the city's Stage 2 LRT project, the Trillium Line will be extended in the south, including a branch to Macdonald–Cartier International Airport and the EY Centre, with four new stations at South Keys, Leitrim, Bowesville and Limebank in Riverside South. There will be a new pocket track, passing track and crossover tracks at South Keys station and the tracks will be fully doubled from the Leitrim Road overpass to Limebank station. The full extension will be grade separated. In addition, two more stations will be built along the existing portion of the line at Gladstone and Walkley. The project will also include a number of other significant upgrades including the lengthening of all existing passing tracks, the purchase of seven new trains, the doubling in length of all existing platforms, the grade separation of the Ellwood diamond to allow Via trains to cross underneath the Trillium Line, the rehabilitation of rail bridges over the Rideau River and of the Dow's Lake rail tunnel, the upgrading of the signalling system to allow the implementation of positive train control, the construction of several new pedestrian tunnels and overpasses, and numerous guideway and vehicle rehabilitation projects. The contract for this project was approved on March 7, 2019, by city council, with construction of the airport spur beginning in mid 2019. The project was expected to be completed by the fourth quarter of 2022 but was delayed initially to October 2023, South Keys station will feature an island platform to facilitate cross platform transfers for passengers arriving from the airport branch to trains bound for Bayview station. The city is not contributing any money to this spur, with the funding instead coming from the federal and provincial governments, as well as the airport authority. On February 22, 2019, the city announced that the selected proponent to construct the project was TransitNEXT, a wholly owned subsidiary of SNC Lavalin. This decision was controversial as the federal government and SNC Lavalin were involved in a political scandal at the time, which led to extra scrutiny by city councillors, with some calling for a delay on the vote to approve the contract in order to allow more time for review. Ultimately Council voted not to delay the approval and the contract was approved on March 7, 2019. The city eventually explained that the decision to award the contract to TransitNEXT was done at the discretion of city staff to get a better deal for the city and was within the rules of the procurement process. An investigation conducted by the city's auditor general later confirmed that the authority delegated by council gave city staff sole discretion on whether to allow a bid to proceed even if it had not met the minimum scoring threshold, and that staff had otherwise correctly followed the entire procurement process that had been approved by council. On May 26, 2023, the Light Rail Transit Sub Committee received an update on the progress of construction for Lines 2 and 4, noting that construction was going well and that handover of the system to the city was expected in approximately the first or second week of October 2023, though that may shift earlier or later pending the results of operational testing across both lines. Michael Morgan, the director of rail construction, reaffirmed that all signs were pointing to Lines 2 and 4 beginning revenue service by the end of 2023 and stated that Line 4 would likely be the first of the two branches to open to the public. It was also revealed that, due to lessons learned from the launch of the Line 1 Confederation Line in late 2019, parallel bus service would be retained across both lines through the end of the first winter they were in operation, so as to mitigate unforeseen disruptions caused by any remaining unexpected events related to the construction. Work on the Stage 2 extension began in mid 2019, starting with the clear cutting of trees along the corridors that will be used by the extension. Construction of the airport spur was expected to be completed in 2020 to give the airport authority time to rebuild the terminal and connect it to the future station.

Extending the Trillium Line across the Ottawa River into Gatineau across the Chief William Commanda Bridge had been proposed as early as the original pilot project proposal. The city's certificate of fitness for the Trillium Line, issued by the Canadian Transportation Authority in 2001, indicates that it operates between the provinces of Ontario and Quebec, despite the line never having actually operated across the river. The city even considered converting the rail bridge into a pedestrian crossing at one point. When the city announced the contract awards for Stage 2, it also presented a map of the O Train network that included proposed extensions that would be a part of a Stage 3 phase, including extensions to Kanata, Barrhaven, and Gatineau. On September 24, 2019, the cities of Ottawa and Gatineau jointly announced that they no longer intended to use the Chief William Commanda Bridge for any kind of rail connection, citing capacity concerns at Bayview station. The bridge was later opened in September 2023 as a multi use pedestrian pathway.

as of 2019, 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 Trillium Line stations have large, bus style sheltered waiting areas for passengers. All stations have level boarding platforms to allow for wheelchair 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). +Trillium Line (Line 2)StationNotes The northbound terminus for the Trillium Line, this bilevel station provides an interchange with the Confederation Line (Line 1) in a fare paid zone and direct access to rapid, frequent and local bus routes on the north side of Albert Street. Bus routes on the south side of Albert Street near Tom Brown Arena are accessed via a multi use pathway which runs alongside and under Albert to connect with the station's first level. Two public washrooms are located next to the Trillium Line waiting area on the first level. The station is located on a stub end track branching off from the railway line, immediately under the Albert Street overpass. It is the closest Trillium Line station to downtown Ottawa. As part of the Stage 2 South expansion, the station will have its platform doubled in length and become double tracked, with an at grade, semi covered pedestrian connection linking the two platforms at the north end of the station. An additional bilevel station building is being built at the southwest corner of the station, which include a pedestrian bridge which will cross the train tracks to link to the future Trinity multi use development project. The National Capital Commission's plans for redeveloping LeBreton flats is considering the land immediately northeast of the station for an NHL calibre arena, potentially to house the Ottawa Senators in the future. Originally planned to be part of the pilot project but was cut for budgetary reasons. A passing loop was added in 2013 to increase train frequency and line capacity. It serves Government of Canada offices in the surrounding area, including Canada Post. The Stage 2 South expansion will see the station platform doubled in length in order to accommodate the longer Stadler FLIRT train sets. The Government of Canada is currently in the process of planning a major redevelopment of nearby buildings into a modern, mixed use community. Originally planned to be part of the pilot project but was cut for budgetary reasons. StationNotesOttawa Hospital Civic CampusAs part of the construction of the new location for the Civic Campus of the Ottawa Hospital southwest of Preston and Carling, the City of Ottawa has protected a grade separated connection to allow for safe passage from the new hospital campus and the Trillium Line. This could be in the form of a brand new station south of Carling Avenue and directly east of the campus or in the form of a protected passage across Carling to Dow's Lake station. Both options are protected for double tracking and electrification in the far future. Collector Road HA future connector road located south of Earl Armstrong Drive and closer to the eastern edge of Riverside South has zoning protection for an overpass integrated with a station above the Line 2 guideway. Collector Road G A future connector road located south of Earl Armstrong Drive and closer to the eastern edge of Riverside South has zoning protection for an overpass integrated with a station above the Line 2 guideway. Ceremonial A future connector road located east of Limebank and south of Earl Armstrong has zoning protection for an overpass integrated with a station above the Line 2 guideway. This would provide more direct access to the northeast and southeast quadrants of the future Riverside South Community Core, located at all four corners of the Earl Armstrong / Limebank intersection.

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 Trillium Line fleet, which included standstill maintenance of the retired Bombardier Talent trains until March 8, 2018. 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 will be built adjacent and to the west of the existing facilities. The construction of the new yard facilities began in 2019.
