FAQs and resources

On October 10, 2024, the City of Calgary and the Government of Alberta released a statement explaining that they agreed to continue design work on the southeast segment (4 Street S.E. to Shepard). Simultaneously, AECOM is developing a revised route for the downtown on behalf of the province, which is expected to be submitted before the end of 2024.

Construction remains active on the Beltline Downtown Utility Relocation Program and the 78 Avenue Project in Ogden.

In early 2025, we expect City Council to decide on the province’s revised downtown alignment. The outcome of this decision will inform whether the Green Line will progress to construction. 

The Green Line LRT will bring many benefits to Calgarians, including those who won't use it. Some benefits include:

• Reducing greenhouse gases by 26,750 tonnes annually
• Shifting 4.8 million trips from vehicles to transit each year
• Easing congestion on roads and existing transit service
• Creating 20,000 direct and indirect jobs during construction
• Spurring residential and commercial development, including opportunities for 114,000 new housing units within 800m of stations

It is too early to provide a specific date. Based on projects of similar size and scale, it should take approximately six years to build. The construction schedule will be shared on the website once it is established.

Phase 1 of Green Line is the largest infrastructure investment in Calgary’s history. It is a megaproject and requires the construction of stations, tracks, multiple bridges and elevated guideways, a maintenance and storage facility for Light Rail Vehicles (LRVs), Park and Ride facilities and much more.

Comparing the scale and timeline to other LRT projects in Calgary:

• The first leg of Calgary’s LRT system spanned 12.5 kilometres from Anderson Station in the south to downtown with 16 stations and took four years to construct.
• The West LRT expansion from downtown to 69 Street Station spanned 8.2 kilometres of track, with six stations and took three years to construct.

Bow Transit Connectors (BTC) was announced as Green Line’s Development Partner in May 2023.  BTC brings shared expertise in underground, above-ground structures, and LRT design and construction to deliver Phase 1 of the Green Line LRT Project.

During the Development Phase, BTC is advancing design while the project cost, schedule and risk allocation are negotiated. Their teams will be supported with local contractors, suppliers, and trades.

An early works program, currently underway, is being performed by PCL Construction, the third-party utilities (ENMAX, Telus, etc.) and Graham Construction. 

Low-floor LRVs are now the preferred choice for new LRT systems across North America because they offer improved accessibility, enhanced vehicle and pedestrian safety, and the ability to integrate easily into the community. 

With low-floor LRVs, train stations at street-level don’t need long ramps, stairs, or large platform structures. The low platforms are curb height (33 centimetres compared with 98 centimetres for high-floor trains), which allows for simpler station designs, resulting in cost savings when building the stations.

The Urbos 100 low-floor LRVs will operate exclusively on Green Line. Due to the low-floor design, the station platforms on the Red and Blue Lines are too high. There are also differences with the existing electrical network that prevents the Green Line LRVs from running on the Red and Blue lines.

It was determined in 2019 that the best option was to build an LRT bridge over the Bow River, connecting Eau Claire station to Crescent Heights. City Council approved this plan in 2020. However, this work is outside the scope of Phase 1 construction.

More information about the preliminary planning and design of the Bow River Bridge is here.

Phase 1 will not connect to YYC Calgary International Airport but there are plans for an Airport Transit Connector linking both the Green Line and Blue Line to the airport.  Visit our future extensions page for more information.

In July 2023, the City of Calgary announced a study to identify the optimal rail connection and alignment between downtown Calgary and the airport. The study will include a ridership review, and development and evaluation of different alignment scenarios. For more information, visit the Airport Transit Study page.

The Alberta government’s vision for a Passenger Rail Master Plan was announced in Spring 2024. It will require a strong intermodal transit network in Calgary to achieve its goals. The Green Line team has been working closely with the Alberta government to integrate the 4 Street S.E. station with their plans for a “Grand Central Station” near Stampede Park.
