The Digital Revolution in Transit: Vancouver’s Canada Line and Its Digital Twin

In an era increasingly defined by technological advancement, the transportation sector is not lagging behind. One remarkable innovation has been the implementation of a digital twin for the Canada Line, a critical transit artery in Vancouver, British Columbia. Managed by InTransitBC—a partnership of SNC-Lavalin, the Investment Management Corp. of BC, and the Caisse de Depot et Placements de Quebec—this initiative marks the first use of a digital twin in a North American rail system for predictive maintenance and infrastructure planning.

What is a Digital Twin?

At its core, a digital twin is a virtual representation of a physical asset—like the Canada Line—that provides real-time data analytics. This digital counterpart mirrors the operations of its physical twin, allowing for unprecedented insights into performance, maintenance needs, and data management.

The Journey Begins

The development of the digital twin commenced in 2021 with Atkins Global, a member of the SNC-Lavalin Group. The project faced unique challenges, particularly because the Canada Line was built prior to the digital era. Ryan Versteeg-Biln, director of asset management, emphasized the importance of taking a user-centric approach: “What do we need as operators? What are the pain points?” This method ensured that the digital twin would meet real-world needs and effectively manage the myriad complexities of an aging transit system.

The Role of Cutting-edge Technology

To establish the digital twin, the project employed an array of modern technologies, including drones, train-mounted scanners, and remote sensors. These instruments gather data from critical assets, which the digital twin then analyzes to identify faults, improve maintenance efficiencies, and bolster safety measures. This data-centric approach not only optimizes passenger flow but also prioritizes operational excellence.

A Framework for Asset Management

Transforming a 12-year-old system with an outdated documentation framework into a high-tech digital model was no small feat. Ron Powell, general manager for Canada Line operations, pointed out that many modifications made over the years had not been documented. Through LiDAR scans, the digital twin now provides a current and consolidated asset management system, bridging the information gaps that have existed for years.

“This opportunity to connect these data sources into a unified framework is a benefit itself,” Powell remarked. With the new system, operators can access information on procurement, finances, maintenance workflows, and more—offering a comprehensive view of every asset.

"Golden" Assets: The Heart of Operations

One of the standout features of the digital twin is its focus on critical assets, notably the “golden” switches. These components manage train movements every three minutes: half dispatching towards the airport and half towards Richmond, B.C. Losing functionality at the switch could significantly disrupt service. By utilizing AI-driven algorithms that analyze real-time data—including every movement of the switch—the digital twin can predict maintenance needs before they become urgent, ensuring continuity and reliability of service.

Scaling Toward a Greener Future

The vision does not stop with improved efficiencies. Versteeg-Biln highlights the potential to leverage insights gained from the Canada Line digital twin for broader applications, including the decarbonization of infrastructure. As they progress, the team envisions that tools and strategies developed here could be adapted for use in other transit systems across North America.

Collaborative Efforts in Transit Improvement

TransLink, the governing body for Metro Vancouver’s transportation network, is closely monitoring the Canada Line’s success. They are in discussions with ProTrans BC—SNC-Lavalin’s subsidiary that operates the Canada Line—about the potential for similar digital twinning strategies for the Expo and Millennium SkyTrain lines. This experimentation could pave the way for transformative changes in how urban transit systems are managed and maintained.

Conclusion

The integration of a digital twin for the Canada Line is not just a technical milestone; it represents a visionary leap toward more efficient, safe, and sustainable public transportation. As cities worldwide grapple with urbanization and aging infrastructure, the lessons learned from Vancouver’s innovative approach may well serve as a blueprint for the future of transit systems elsewhere. By embracing digital transformation, public transportation is not just catching up with the digital age; it is setting the pace for the industries of tomorrow.
