The Trillium Line (French: Ligne Trillium), also called O-Train Line 2 (French: Ligne 2 de l'O-Train),[3] is a diesel light rail transit (DLRT) service in Ottawa, Ontario, Canada, operated by OC Transpo.[4][5][6] 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 8 kilometres (5 mi) 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.[7] All stations except Carleton 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.[8]

On May 3, 2020, the line was shut down for a four-year upgrade and expansion project, which will add eight stations and 16 kilometres (10 mi) of track, including a spur to Macdonald–Cartier International Airport. During its closure, service along the line is being provided by buses. The upgraded and expanded line is expected to reopen in the third quarter of 2024.[9][10][11][12][13]

History[edit]

Pilot project[edit]

The Trillium Line was introduced on October 15, 2001, as a pilot project to provide an alternative to the 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 CA$21 million, 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 subdivisions of Bytown and Prescott Railway[14]), 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.

From 2001 until 2015,[15] the system used three diesel-powered Bombardier 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' standards for 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 light rail line (the Confederation Line), the O-Train name was applied to the entire system, and the north–south line was renamed the "Trillium Line".[16]

Original service[edit]

Carleton was previously the only station with two platforms. Note retractable platform extenders at solid yellow markings.

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.[17] In mid-2011, the Trillium Line carried an average of approximately 12,000 riders each day.[18]

Awards[edit]

In June 2002, the O-Train Light Rail Transit project received the Canadian Urban Transit Association’s Corporate Innovation Award.[19]

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.[20]

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.[19]

Criticism of pilot project[edit]

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, benefited from the Trillium Line pilot project, as it connected the university to the busy Ottawa Transitway system.

The other criticism is that there is very low ridership of the trains compared to some very crowded bus lines such as the 90–99 series routes. One fully loaded Trillium Line train carries 285 passengers compared to 131 passengers for an articulated bus.[21] The O-Train schedule is limited by track capacity.

Early extension plans[edit]

Main article: 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 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.

Service improvements[edit]

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.[18] The project would finally cost $60.3 million.[8]

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).[8][22] 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.[8] Six new Alstom Coradia LINT trainsets (replacing the three older Bombardier Talent units) and the two extra passing loops allowed the number of trains on the line to double to four.

Expanded service began on March 2, 2015, but suffered numerous problems during the first week.[15] Although the changes were intended to improve frequency to eight minutes, the Trillium Line would ultimately operate at twelve minute frequency.[23] 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.[24]

Derailment[edit]

On August 11, 2014, train C3 derailed while traveling northbound over the switch just south of Carleton station.[25] 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[26] 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.[27]

Stage 2 expansion[edit]

As part of the city's Stage 2 LRT project, the Trillium Line will be extended 16 kilometres (9.9 mi) in the south, including a 4-kilometre (2.5 mi) 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.[28] 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.[29] The contract for this project was approved on March 7, 2019, by city council,[30] 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 then delayed to October 2023,[12] and most recently delayed until April 2024 at the latest.[10]

The 4-kilometre (2.5 mi) airport link will run from Macdonald–Cartier International Airport north to South Keys station, where riders will need to change trains to continue to Bayview station.[31] 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.[32]

On February 22, 2019, the city announced that the selected proponent to construct the project was TransitNEXT, a wholly owned subsidiary of SNC-Lavalin.[33][34] 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.[30] It was later revealed that TransitNEXT's bid had not met the minimum technical scoring threshold in order to be considered, which continued the controversy.[35] 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.[36] 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.[37]

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.[38] 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.[39]

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.[40][41]

Further extensions[edit]

Bayview is an interchange station that serves Line 1 and Line 2

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.[42] The city even considered converting the rail bridge into a pedestrian crossing at one point.[43] 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.[44] 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.[45] The bridge was later opened in September 2023 as a multi-use pedestrian pathway.[46]

Stations[edit]

Main article: List of O-Train stations

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)
Station Notes
Bayview 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.[47] 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.
Corso Italia Originally planned to be part of the pilot project but was cut for budgetary reasons.[48] A passing loop was added in 2013 to increase train frequency and line capacity.[22] It is the site of a future Stage 2 South station that will feature two platforms on a double track extending from approximately the Beech Street pedestrian bridge all the way to the terminus at Bayview station.[28] The station building is being structurally engineered to support upward, mixed-use expansion in the future.
Dow's Lake Located at Carling Avenue and Preston Street, just north of Dow's Lake. The station is currently single-tracked despite the Stage 2 South expansion; however, the City of Ottawa has maintained that double-tracking this station is still a long-term option, as well as connecting the station directly to either or both the new Civic Hospital Campus of the Ottawa Hospital or a potential future station servicing the new hospital campus specifically. South of this station, the train enters a tunnel to pass under Dow's Lake.
Carleton Serves Carleton University and has separate tracks and platforms for each direction. Until the upgrade of the line in 2013, this station had the only passing loop along the line.
Mooney's Bay Originally known as "Confederation" after the Confederation Heights area (Heron and Bronson intersection), the station was renamed on December 24, 2018, to avoid confusion with the Confederation Line.[49] 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.
Walkley Originally planned to be part of the pilot project but was cut for budgetary reasons.[48] A passing loop was added in 2013 just north of Walkley to increase train frequency and line capacity.[22] It is the site of a future Stage 2 South station immediately south of Walkley Road and just east of the existing Transitway station.[28] Despite being single-tracked, the City of Ottawa has maintained that double-tracking the station is in its long-term plans.
Greenboro Provides an interchange with a large Transitway station, which has a large park-and-ride lot and is located next to the South Keys Shopping Centre. The Trillium Line platform is level with the pedestrian overpass crossing the Transitway. This is also the only Trillium Line station, prior to the completion of the Line 2 South expansion, to include a fare-paid transfer zone.
South Keys Future connection between Line 2 and the Airport Rail Link (Line 4). It will be an island-platform station in the middle of a double-tracked segment and include a pocket track just north of the station for storing a trainset on layup. The Line 4 trains are projected to arrive and depart in sync with the Line 2 trains.
Leitrim Adjacent to the existing bus station and park-and-ride lot. This Stage 2 South station will feature two platforms, an expanded park-and-ride lot, and a reconstructed bus operators' building and bus loop intended to facilitate increased service and easier transfer connections between light rail and bus.
Bowesville Located just east of Bowesville Road. This station will feature two platforms and will be the site of a new park-and-ride lot, which will have the ability to be expanded in the future.
Limebank Southbound terminus for the Trillium Line
Airport Link (Line 4)
Station Notes
South Keys The northbound terminus for the Airport Link (Line 4), this station provides an interchange with the Trillium Line (Line 2) in a fare-paid zone and access to the Transitway nearby.
Uplands Will be built East of Uplands Drive next to the EY Centre and will feature two platforms. It will be the location of the only passing loop on the spur.
Airport The southbound terminus for the Airport Link, it will be located at the Ottawa Macdonald–Cartier International Airport and built into the renovated and expanded terminal at the departures level.
Longer-term expansion potential[50]
Station Notes
Ottawa Hospital Civic Campus As 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 H 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.
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.

Fleet[edit]

Interior of Alstom Coradia LINT

The Trillium Line initially used three Bombardier Talent diesel multiple unit (DMU) trains for service. Each train (numbered C1–C3)[26] consisted of three cars, with the front and rear powered and the centre towed. The trains were originally ordered by Deutsche Bahn and later delivered to OC Transpo. After being retired in 2015, the units were put up for auction multiple times[51][26] but a deal to sell the vehicles was never successfully established. They are now slated to be scrapped.[52]

In September 2011, Alstom announced that it would deliver six new two-car Coradia LINT train sets in 2013;[53] the trains were handed over to OC Transpo in June 2013.[54] These trains were put into service on March 2, 2015, and the Bombardier Talent units were subsequently retired.[55]

On May 3, 2018, it was announced that the city would be purchasing seven new Stadler FLIRT trains to use on the extended Trillium Line after the completion of Stage 2.[56] These trains will be approximately 80 metres (262 ft) long, which is double the 41-metre (135 ft) length of the current Coradia LINT trains. The new trains will operate alongside coupled pairs of the existing LINT trains on the main line as part of a mixed fleet. These vehicles were manufactured in Switzerland before being transported to Canada for final assembly.[57] The trains have a diesel-electric drive with the possibility of future electrification. The first FLIRT vehicle was delivered on October 7, 2021,[58] and began testing on the weekend of January 15, 2022.[59]

Facilities[edit]

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.[60] 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.[61] The construction of the new yard facilities began in 2019.[62]
