As Canada’s busiest gateway, the Vancouver terminal is a cornerstone of North American trade. Faced with geographic constraints and limited expansion space, the Canadian National Railway (CN) is prioritizing smarter operations over physical growth. By investing in infrastructure upgrades, enhancing scheduling coordination, and optimizing train capacity, CN is ensuring the continued flow of freight through one of the most vital—and most space-constrained—ports on the continent.

1. Vancouver: A Critical Yet Constrained Port

CN operates nearly 70% of all trains in and out of Vancouver. The Second Narrows Rail Bridge und Thornton Tunnel are essential links to the North Shore terminals, which handle more trade than any other Canadian port.

However, Vancouver is surrounded by water, development, and mountainous terrain, making physical expansion difficult. CN CEO Tracy Robinson called the growth prospects at the Vancouver terminal compared to Prince Rupert, CN’s other major gateway port in British Columbia, a matter of “inches, not miles.”

2. Key Infrastructure Upgrades in Vancouver

To increase fluidity and squeeze more capacity from existing infrastructure, CN has made targeted investments:

• Thornton Tunnel Upgrade: Improved ventilation reduced train spacing from 20 minutes to under 10.
• 19,000-foot Passing Siding: Enables staging of two trains near the bridge instead of at Thornton Yard.
• Holdom Avenue Overpass (2027): Removing a key level crossing in Burnaby will allow the staging of two additional trains.
• New Sidings: Added near Vancouver and in Kamloops to support operational fluidity.

These upgrades are essential for maximizing throughput, especially during peak movements of bulk commodities like grain.

3. Collaborative Scheduling and Traffic Management

To synchronize rail and marine operations, CN and the Vancouver Fraser Port Authority are leveraging:

• Active Vessel Traffic Management Program
• Centralized Scheduling System

These systems give CN better visibility into bridge lift schedules, enabling more precise timing of train movements and reducing delays caused by conflicts with vessel traffic in the Burrard Inlet.

4. Weather-Related Bottlenecks: The Grain Challenge

One major operational challenge identified by CN is grain terminal unloading in rainy weather. Bulk vessel loading is suspended during rain, which leads to a chain reaction:

• Grain trains get delayed
• Railcars are held at origin or staged in Kamloops
• Backlogs impact farmers and shippers across the prairies

To solve this, CN partnered with grain companies and the port to identify and fix the true bottlenecks—some of which lie outside the railroad’s control. Solutions are now being developed to enable weather-independent grain loading, reducing the impact of rain delays.

5. Prince Rupert: CN’s Other Growth Frontier

While Vancouver presents capacity challenges, Prince Rupert—a smaller, more remote port—offers significant growth potential. CN is the exclusive rail provider to Prince Rupert, which has available land for expansion and a strong local interest in development.

According to Robinson, growth in Rupert will be “step-function,” while Vancouver’s growth will be incremental and coordination-based.

6. The Bigger Picture: A Coordinated Supply Chain

Robinson emphasized that railways alone cannot solve congestion. True fluidity requires collaboration across the entire supply chain, einschließlich:

• Terminals
• Vessel operators
• Port authorities
• Shippers

She explained that optimizing individual parts doesn’t guarantee system-wide efficiency. Only when all parties work together can bottlenecks be resolved holistically.

Conclusion: Engineering Growth Without Expansion

Despite Vancouver’s geographical constraints, CN proves that capacity growth doesn’t always mean more space—it can mean smarter use of existing infrastructure. Through investment, coordination, and technology, CN aims to keep the Port of Vancouver flowing efficiently, supporting Canada’s trade economy now and into the future.
