Calgary Airport Rail Connection Study
September 2025 - Completion of the Final Technical Report
As the City of Calgary grows, a rail connection to the Calgary International Airport will improve access for those who live, work, and travel within our city.
In response to increasing public and private interest in rail connections, The City of Calgary, in partnership with the Government of Alberta, launched the Calgary Airport Rail Connection Study. The goal of this study is to identify the optimal rail connection between Downtown Calgary and the airport as part of an integrated transportation network.
The findings of the study were presented at the Infrastructure and Planning Committee on January 8, 2025. View the Calgary City Council agenda.
The final technical report was completed in the first quarter (Q1) of 2025 and was shared with the Government of Alberta to support the development of the Passenger Rail Master Plan. View the Executive Summary of the technical report.
Timelines
Background
RouteAhead, Calgary Transit's 30-year plan, identifies a transit connection to the airport (via the Blue Line and Green Line LRT) as a key transit priority. As such, in 2020, the Council-approved Airport Transit Line Study proposed a transit connection between the Blue and Green Line LRT on Airport Trail/96 Avenue North via the Calgary International Airport. Since then, three private rail developers have proposed projects that would also connect downtown Calgary to the airport, including the Calgary-Banff/Bow Valley passenger rail project and two high-speed connections between Edmonton and Calgary.
Alberta Transportation and Economic Corridors has a mandate to explore cost-sharing arrangements with the private sector and/or municipalities that support economic investment in Alberta’s transportation system. This includes taking into consideration public transit, heavy rail, and bridge infrastructure that better connect Calgary and Edmonton airports to their downtowns, regional communities to Calgary and Edmonton, and Calgary to the province’s Rocky Mountain parks system.
The Government of Alberta committed $3 million in provincial funding to the City of Calgary to lead the Calgary Airport Rail Connection Study.
Consultant selection and engagement
On October 17, 2023, Arup, was selected as the successful consultant to assist with the study. As part of the study, The City developed a transparent process, ensuring participation from all key interest-holders through an Input Committee, providing an opportunity to share perspectives and interests.
The Input Committee consisted of representatives from The City, the Government of Alberta, Canada Infrastructure Bank, Calgary Airport Authority, Canadian Pacific Kansas City (CPKC) railway and private rail developers.
Study process
The Calgary Airport Rail Connection Study looked holistically at rail access between Calgary International Airport, Downtown Calgary, and other regional destinations. The study considered the interaction of public and private proposals and established a comprehensive understanding of technical factors, route options and anticipated ridership, using past studies and current research.
The objectives of the Calgary Airport Rail Connection Study included:
- Developing The City’s long-term vision for rail access between Downtown Calgary and the Calgary International Airport, considering connections to Edmonton, Bow Valley and Banff;
- Establishing a collective understanding of route options and ridership opportunities for a rail connection between Downtown Calgary and the Calgary International Airport;
- Advancing planning, design, and technical assessments to establish an optimal functional route through a technically and physically constrained corridor;
- Analyzing the benefits, costs, opportunities, and risks associated with various route and station options to inform short to long-term transportation and land use planning; and
- Providing clear direction on where to prioritize investment in the near term to support a customer-focused service that delivers value and respects taxpayers’ contributions.
Study findings
The preferred option builds on the 2020 Airport Transit Line Study, focusing on improving connectivity between Calgary International Airport (YYC) and downtown Calgary, while integrating with the Blue and Green Line LRT systems. It is designed to meet the needs and priorities of Calgarians, as outlined in the Calgary’s transit plan (RouteAhead), while also preserving the flexibility for future regional transit connections.
The preferred option builds on the 2020 Airport Transit Study with key highlights:
- East-West Connection: Building on findings from the 2020 Airport Transit Line Study, the preferred option ensures that the east-west connection between the Blue Line and Green Line LRTs and the Calgary International Airport is maintained. This connection links northeast and northwest Calgary communities, where approximately 60% of the demand for airport service was identified. Connecting the Calgary International Airport to the Blue Line and Green Line LRT systems will provide a critical service for both travelers and employees, addressing the northeast and northwest demand we identified through our study. Once fully built, the preferred option would allow for up to 8 trains per hour (one every 7-8 minutes) between the Green Line LRT, the airport, and the Blue Line LRT.
- Direct Airport-Downtown Link: The alignment does not preclude a direct connection between the airport and downtown Calgary, preserving opportunities for enhanced connectivity. The alignment was modified from the 2020 Airport Transit Line Study (including larger radii) to allow for regional rail services to serve the airport in the future, which would be delivered by private rail providers. Once complete, this option would allow for up to four trains per hour (one every 15 minutes) between downtown Calgary and Calgary International Airport.
- Regional Rail Compatibility: The proposed rail infrastructure is designed to be compatible with future regional and intercity rail services, ensuring long-term integration with broader transit networks.
- Phasing Flexibility: This preferred option supports a phased development, allowing for incremental expansion as funding becomes available. It also enables prioritization of the east leg that would connect the Blue Line LRT to the Calgary International Airport.
Next steps
- This Study has identified a functional concept that would be subject to further refinement and design. The Final Report from this Study will also be shared with the Government of Alberta to inform the ongoing Passenger Rail Master Plan.
- The City will continue to advance the design of the Blue Line extension from Saddletowne Station to 88 Avenue N.E., a crucial step in connecting the City’s transit system to the airport.

Frequently Asked Questions
What are the three private rail proposals?
Three proposals have been submitted by private rail developers all of which include a connection to Calgary International Airport:
- High-Speed Rail (HSR) – Prairie Link Rail Partnership proposes high-speed rail connecting Edmonton, Red Deer, and Calgary via the airports in Calgary and Edmonton.
- Calgary Airport Banff Rail - Liricon Capital Ltd and Plenary Americas LP propose a rail solution connecting Calgary International Airport, downtown Calgary, and the Bow Valley (with terminus in the Town of Banff)
- TransPod (Hyperloop) - TransPod proposes a hyperloop connection between Edmonton, Red Deer, and Calgary via the airports in Calgary and Edmonton.
Who will develop this rail connection? How much will it cost?
The Calgary Airport Rail Connection Study is a technical study that focused on identifying the best route for a connection between downtown Calgary and the airport while considering the private rail proposals. It does not address ownership or operation of the service.
When can we expect to see shovels in the ground?
Construction will depend on future project proponents and funding sources (through public and/or private partnerships) who will use the study’s findings to move forward.
Did the study include public engagement?
- As part of the 2020 Airport Transit Line Study, the City conducted public engagement to identify key priorities for Calgarians which included: integration with existing transit systems, speed, cost-effectiveness, and accessibility.
- The Calgary Airport Rail Connection Study is a technical study focused on determining the optimal route between downtown and the airport. Public engagement was not undertaken for CARCS, but the public engagement findings from the 2020 study were incorporated in the screening criteria that helped to determine the preferred option. Should a project proponent (private or public) choose to advance a specific project, public consultation may be conducted at that time.
Does The City or Government of Alberta have a preferred project or proponent?
The study has focused on determining the optimal connection from downtown Calgary to the Calgary International Airport, but it has not addressed any specific private developer proposals or who would own and operate the services.
