Green Line (Calgary)

File:Green Line Full Vision Alignment Map.png

The Green Line LRT will be an urban and suburban light-rail line using low-floor trains, the CAF Urbos 100, integrated as part of Calgary's CTrain system. Like the rest of Calgary's rail transit network, the Green Line will be entirely powered by wind power.{{Cite web|url=https://pub-calgary.escribemeetings.com/filestream.ashx?DocumentId=9089|title=The City of Calgary: Investing in the Calgary Green Line|accessdate=September 5, 2024}} Operation of the line will be publicly funded by municipal taxation along with rider fares, and will be administered by Calgary Transit.

Generally, stations will be smaller and less elaborate than existing CTrain stations, due to the use of low-floor trains. The SE Segment, from Shepard to Event Centre/Grand Central Station, will run as a light metro similar to the existing Red Line and Blue Line, with dedicated tracks, bells and gates on at-grade crossings and free standing stations. The track between 26 Avenue SE station and Ramsay/Inglewood station will be elevated on a guideway similar to the existing Sunalta station.

Future phases of the full 46km Green Line vision include a bridge crossing the Bow River northwards, with two multi-use pathways, and connecting to Centre Street, north of the Centre Street Bridge. The train will then run northward in the centre two lanes of Centre Street in a dedicated right of way as an urban tramway, leaving two lanes for car traffic south of McKnight Boulevard and four lanes north of McKnight Boulevard. Stations sound of 26 Avenue SE will be at-grade stations with a section of elevated track crossing the intersection of Barlow Trail SE and 114 Avenue SE.

The train will run without gates, bells or fences on most at-grade crossings along Centre Street. The train will then continue northward; tracks will eventually enter into the median of Harvest Hills Boulevard, and the line will eventually span north of Stoney Trail into the exurban community of Keystone.{{Cite web|title=Green Line - Segment 2 :: Green Line Stage One|url=https://engage.calgary.ca/greenline/green-line-segment-2|website=Engage |access-date=May 18, 2020}}{{Cite web|title=Green Line Long Term Vision Report|url=https://lrtonthegreen.ca/wp-content/uploads/2020/05/Green-Line-Long-Term-Vision-Report-Part-1.pdf}}

{{main|List of CTrain stations}}

The full vision of the line will run from north-central to southeast Calgary on {{Convert|46|km}} of track and will feature 29 stations. This will bring the total number of CTrain stations in Calgary to 74. The planned Green Line corridor is currently served via three bus rapid transit (BRT) routes: Route 300 (operating the Calgary International Airport and downtown, primarily along Centre Street), Route 301 (between North Pointe and downtown){{cite web |url=https://www.calgarytransit.com/sites/default/files/route/301_apr_2019.pdf |title=BRT North/Downtown, Route 301 |publisher=Calgary Transit |access-date=May 16, 2019}} and Route 302 (between Seton and downtown).{{cite web |url=https://www.calgarytransit.com/sites/default/files/route/302_apr_2019.pdf |title=BRT Southeast, Route 302 |publisher=Calgary Transit |access-date=May 16, 2019}} Like the Red Line and Blue Line, the Green Line will be built in stages. Stage one of construction will extend from 16 Avenue N at 16 Avenue N station, through downtown Calgary, to 126 Avenue SE at Shepard station.{{Cite web|url=https://www.calgary.ca/content/dam/www/transportation/green-line/documents/green-line-benefits-infographic-placemat.pdf|title=Calgary Green Line Info graphics Place mat|accessdate=September 5, 2024}}

Stage 1 of construction will be built incrementally in smaller phases:{{cite web |title=Green Line LRT announces Phase 1 RFQ shortlist winners - constructconnect.com |url=https://canada.constructconnect.com/joc/news/infrastructure/2022/08/green-line-lrt-announces-phase-1-rfq-shortlist-winners |website=Journal Of Commerce |access-date=October 30, 2022 |date=August 1, 2022}}

• Phase 1: Lynnwood/Millican to Eau Claire, including the downtown tunnel (under construction) with Centre Street S being deferred to a future phase and a Maintenance and Storage Facility being built near the Highfield Station.
• Future Phases: Eau Claire to 16 Avenue N station including the Bow River crossing, Lynnwood/Millican to Shepard, and Centre Street S
• Airport Phase: 96 Avenue N to 88 Avenue NE

Though the alignment and general design of future expansions have been approved by the city council, the timeline and funding of future extensions has not yet been determined. Construction stage one builds the most complex and the most expensive segment of the line first - allowing incremental, relatively simple expansion of the line as funding becomes available. The full build-out of the line is estimated to require an additional CA$2–3 billion.

In 2019, several potential Stage 2 build-outs were evaluated for variable amounts of potential future funding. These were:{{cite news|author=Hudes, Sammy|date=March 18, 2019|title=Next Green Line phase might only extend north to 64th Avenue|newspaper=Calgary Herald|url=https://calgaryherald.com/news/local-news/next-green-line-phase-might-only-extend-north-to-64-avenue-leaving-advocates-disappointed|access-date=May 16, 2019}}

When completed, Stage 1 of the Green Line will feature:

• 40–45 low floor light rail trains, each {{Convert|40|m}} long
• {{Convert|20|km}} of track
• 15 stations (10 at-grade, 3 underground, 2 elevated)
• 3 park and ride facilities with a total of 1,800 – 1,900 stalls (Lynnwood/Millican, Douglas Glen, and Shepard)
• {{Convert|1|km}} of elevated track between Ramsay/Inglewood to 26 Avenue SE stations
• 1 light rail vehicle (LRV) maintenance and storage facility, at Highfield{{Cite web |title=Highfield |url=https://www.calgary.ca/content/www/en/home/green-line/stations/highfield.html |access-date=August 4, 2024 |website=Green Line LRT}}

When the full line is complete, it will also feature 12 bridges, 10 park and ride facilities (with 5,000 to 6,000 parking stalls), 10 tunnels (including the {{convert|2|km|adj=on|abbr=on}}-long centre city tunnel from 2 St SW in Eau Claire to 11 Av SE in Victoria Park), a bridge connecting Eau Claire to Centre Street North, and 2 LRV maintenance and storage facilities (at Shepard and 96 Avenue N).{{cite report|chapter-url=https://www.calgary.ca/Transportation/TI/GreenLineDocuments/GL-Long-Term-Vision-FINAL-Reduced_Part3.pdf|title=Green Line LRT Long Term Vision: 160 Avenue N to Seton|date=October 2017|publisher=City of Calgary|access-date=May 16, 2019|chapter=Alignment and Station Overview}}{{Dead link|date=December 2024 |bot=InternetArchiveBot |fix-attempted=yes }}

When the full vision is completed, from 160 Ave N to Seton, it's expected that 140,000 people will ride the Green Line every day. Stage 1 of construction is expected to have a daily ridership of 65,000 people. The city plans on creating many high density transit oriented development along the line once it is complete similar to how some areas around the existing C-Train lines have been redeveloped. The line will reduce travel times for existing north-central BRT and southeast BRT riders by an average of 25 minutes.

The project is part of the cities plan to reduce emissions and meet Canada's Paris Agreement targets. Like the current C-Train Lines, the Green Line will be entirely powered by wind generated electricity and is expected to reduce greenhouse gas emissions by 67,000 tonnes of carbon dioxide per year, equivalent to 14,200 fewer vehicles on Calgary's roadways.{{Cite web|url=https://www.calgary.ca/content/dam/www/transportation/green-line/documents/GL-Long-Term-Vision-FINAL-Reduced-Part2.pdf|title=The City of Calgary: ADDRESSING CALGARY'S NEEDS WITH GREEN LINE LRT|accessdate=September 5, 2024}}{{Cite web|url=https://pub-calgary.escribemeetings.com/filestream.ashx?DocumentId=9089|title=City of Calgary: Investing in Calgary's Green Line LRT|accessdate=September 5, 2024}}

Deerfoot Trail is currently the primary transportation route from north-central to southeast Calgary. It is the busiest freeway in Alberta, and suffers from chronic congestion. Calgarians spent an average of 15.7 hours in peak hour congestion in 2016.{{Cite web|title=CBC: Deerfoot Trail congestion|url=https://www.cbc.ca/news/canada/calgary/city-of-calgary-deerfoot-short-term-improvements-1.4132660}} The Green Line alignment runs roughly parallel to Deerfoot Trail and when finished will provide a competitive alternative to driving on the freeway resulting in an improved quality of life for Calgarians and reduced congestion on Deerfoot and its connecting roads.

Trams ran on the surface of Centre Street for 41 years, from 1909 to 1950.{{Cite web|date=May 10, 2018|title=The City of Calgary's Transit History|url=https://thegauntlet.ca/2018/05/10/the-city-of-calgarys-transit-history/|access-date=June 21, 2020|website=The Gauntlet}} The Green Line will restore the historic alignment of Calgary's trams, running trains on the surface of Centre Street as well.

The Green Line was first envisioned in 1983, two years after Calgary's first LRT line opened.{{Cite web|last=Keating|first=Shane|date=September 20, 2019|title=A (somewhat) Brief History of the Green Line|url=http://www.shanekeating.ca/2019/09/20/a-somewhat-brief-history-of-the-green-line/|access-date=June 22, 2020|website=Shane Keating — Councillor Ward 12}} As early as 1986, the communities of McKenzie Towne, New Brighton and Copperfield had set aside land along 52 Street SE for the future line. In 1987, the city then conducted the Southeast Mass Transit Corridor Study and concluded that southeast Calgary would one day require a dedicated light rail line.{{Cite web|url=https://www.calgarytransit.com/sites/default/files/reports/southeast_lrt_compendium.pdf|title=Southeast Mass Transit Corridor Study|accessdate=September 5, 2024}}

In 2010, the city anticipated that the Green Line would be required before Calgary's population reached 1.25 million, though the city surpassed that population just 5 years later.{{Cite web| title=Calgary's Population, 1958-2019 {{!}} Open Calgary|url=https://data.calgary.ca/Demographics/Calgary-s-Population-1958-2019/as3q-cmd5|access-date=June 22, 2020|website=data.calgary.ca}} Chronic congestion on Deerfoot Trail is partly attributed to the failure to construct the Green Line before the 1.25 million population target.{{Cite web|last=Keating|first=Shane|date=February 24, 2017|title=A Chat About Calgary Congestion|url=https://www.shanekeating.ca/2017/02/24/a-chat-about-calgary-congestion/|access-date=June 30, 2020|website=Shane Keating — Councillor Ward 12}}

In 2011, the city began considering three possible alignments for the north-central leg of the Green Line: along Nose Creek adjacent to Deerfoot Trail, on Edmonton Trail, or on Centre Street. After engagement with the public, the city selected Centre Street as the preferred alignment.{{citation needed|date=October 2024}}

In 2012, the Green Line was proposed as two separate new lines — one from downtown to north central and one from downtown to the southeast.{{cite news|author=Smith, Kevin|date=October 29, 2012|title=Canada's light rail renaissance|work=International Railway Journal|url=https://www.railjournal.com/in_depth/canadas-light-rail-renaissance|access-date=May 21, 2019}} The division of the line was rejected by council.{{Cite web|title=City council approves Green Line, with conditions to keep it on budget|url=https://calgaryherald.com/news/local-news/city-councils-final-green-line-vote-expected-tuesday|access-date=June 30, 2020|website=Calgary Herald}} Through 2016, $101 million had been spent on right-of-way acquisition and preliminary studies.{{cite news |url=https://calgaryherald.com/news/local-news/city-has-spent-101m-on-green-line-lrt-so-far |title=City has spent $101M on Green Line LRT so far, land acquisition going 'pretty smoothly' |author=Klingbeil, Annalise |date=May 16, 2017 |newspaper=Calgary Herald |access-date=May 16, 2019}}

In May 2017, the city revealed the line's suggested alignment and announced it would be built in stages due to the unexpectedly high costs of certain design choices.{{cite news |url=https://calgaryherald.com/news/local-news/first-phase-of-green-line-would-cost-4-65-billion-run-from-crescent-heights-to-shepard |title=First phase of Green Line would cost $4.65 billion, run from Crescent Heights to Shepard |author=Klingbeil, Annalise |date=May 16, 2017 |newspaper=Calgary Herald |access-date=May 16, 2019}} Although the original estimate for the entire 28-station Green Line was $4.5 billion,{{cite news |url=https://calgaryherald.com/news/local-news/green-line-lrt-to-be-phased-in-wont-reach-transit-starved-communities-for-years |title=Green Line LRT to be phased in, won't reach transit-starved communities for years |author=Howell, Trevor |date=February 13, 2017 |newspaper=Calgary Herald |access-date=May 16, 2019}} the cost of stage one alone, including the $1.95 billion cost of the centre city tunnel,{{cite news |url=https://calgaryherald.com/news/local-news/1-95-billion-underground-tunnel-for-green-line-lrt-recommended-by-city |title=$1.95 billion underground tunnel for Green Line LRT recommended by city |author=Klingbeil, Annalise |date=November 2, 2016 |newspaper=Calgary Herald |access-date=May 16, 2019}} was estimated at $4.65 billion.

In 2015, the Government of Canada announced that it would invest a historic $1.53 billion in the Green Line, the single largest federal investment for an infrastructure project in Alberta.{{Cite web|title=Tories announce $1.5B for Green Line LRT project|url=https://calgaryherald.com/news/local-news/tories-announce-1-5b-for-green-line-lrt-project|access-date=March 25, 2021|website=Calgary Herald}} In early 2019, Alberta's NDP provincial government committed $1.53 billion in funding paid for by the provincial carbon tax.{{Cite web|date=January 30, 2019|title=Funding arrangement officially secured for first stage of Calgary Transit's Green Line|url=https://calgary.ctvnews.ca/funding-arrangement-officially-secured-for-first-stage-of-calgary-transit-s-green-line-1.4276069|access-date=June 22, 2020|website=Calgary}} Over time, the City of Calgary set aside funding for the Green Line and has designated a $1.53 billion investment in the project. The Green Line is funded by three roughly equal contributions from all three orders of government.

In late 2019, after the 2019 Alberta General Election, the newly elected United Conservative provincial government cut the Green Line's budget by 86 percent{{Cite web|title=Jason Kenney Cuts Green Line Budget 86%|url=https://www.cbc.ca/news/canada/calgary/green-line-future-provincial-funding-1.5338204}} and passed legislation allowing their government to terminate their contribution "without cause" and with only 90 days notice.{{Cite web|title=Proposed legislation allows UCP cabinet to kill Green Line funding with 90-day notice|url=https://calgaryherald.com/news/local-news/bill-20-allows-ucp-cabinet-to-kill-green-line-funding-with-90-day-notice|access-date=June 27, 2020|website=Calgary Herald}} This move complicated the city's ability to move forward with the project, hindered the city's access to the federal government's investment and raised uncertainty among potential procurement bidders.

On May 12, 2020, the city announced changes to the alignment of the line to keep the project within budget. The revised alignment replaced the deep-earth tunnel under the Bow River with an elevated guideway over the east end of Prince's Island Park. The elimination of the tunnel under the river significantly reduces construction cost and risk.

The changes also brought the line to the surface between 9 Avenue N and 16 Avenue N, running along the two centre lanes of Centre Street in a dedicated right of way. The Green Line north of 16 Avenue N has been planned as a surface running train since the city's 2017 recommendations. The changes also included the addition of 9 Avenue N station in Crescent Heights, increasing the number of stations in stage one of construction to 15, and bringing the total number of stations to 29. Eau Claire station and 4 Street SE station were moved from being at-grade to underground and the Beltline section of the line was moved one block north to run under 11 Avenue South, rather than under 12 Avenue S as initially recommended.

The plan for a tunnel under the intersection of Barlow Trail and 114 Avenue SE was scrapped in favour of an elevated guideway over the intersection, and the park and ride at Shepard station was revised from a parkade to a surface parking lot.{{Cite web| title=Green Line - Segment 1 :: Green Line Stage One|url=https://engage.calgary.ca/greenline/green-line-segment-1|access-date=September 9, 2020|website=Engage}}{{Cite web| title=Green Line - Segment 2 :: Green Line Stage One|url=https://engage.calgary.ca/greenline/green-line-segment-2|access-date=September 9, 2020|website=Engage}}

On July 30, 2024, the city decided on changes to the phase 1 alignment to address the impact of cost overruns. The revised phase 1 alignment runs from Eau Claire but terminates at Lynnwood/Millican instead of Shepard. The new alignment also moves 4 Street SE from underground to at-grade to better integrate with planned future passenger rail and the planned "Grand Central Station", and moves the Maintenance and Storage Facility to Highfield Station instead of Shepard. The change also includes the deferral of Centre Street S to a future phase in order to minimize cost overruns.{{Cite web |title=Green Line LRT moves forward with a revised Phase 1 project and capital request to address rising costs |url=https://www.calgary.ca/content/www/en/home/green-line/green-line-news/article-engine/green-line-lrt-moves-forward-with-a-revised-phase-1-project.html |access-date=August 4, 2024 |website=Green Line LRT }}

Rethink the Green Line has continued its campaign against the Green Line through 2024. The group has been noted for disseminating disinformation about the project and has made objectively incorrect claims in an attempt to garner opposition, such as the unfounded assertion that property taxes could increase by 90 percent if built.{{Cite web |title=Property taxes could increase ... and go as high as 90% to pay for the entire project. |website=Facebook |url=https://www.facebook.com/share/p/YWxPxmTvVFqokWis/ }}

After over a year of delays inflicted by the provincial government, Prime Minister Justin Trudeau, Mayor Naheed Nenshi, members of council, and various other stakeholders gathered at the Oliver Bowen Light Rail Maintenance Facility in Calgary to announce the Green Line would continue as planned.

On June 16, 2020, council voted 14 to 1 to approve construction Stage 1 of the Green Line despite vocal opposition from a small group of wealthy and influential businesspeople. The project received final approval from all three orders of government on July 7, 2021. Several polls conducted in 2020 and 2021 have suggested that the project has popular public support. A poll conducted in June 2020 found 68.7 percent of Calgarians in support of the project with its updated 2020 alignment.{{Cite web|title=New poll shows most Calgarians are in support of Green Line plan|url=https://globalnews.ca/news/7068675/poll-shows-calgarians-green-line-plan/|access-date=June 23, 2020|website=Global News}} According to a 2021 survey conducted by the City of Calgary, 90 percent of respondents said the Green Line is important to the future of the city and 89 percent said it is an important addition to the city's transportation network.
