Your input will help us identify a train technology recommendation for action by the BART and Capitol Corridor Boards of Directors next year.

Imagine a More Connected Future

A new train crossing connecting the San Francisco / Peninsula to Oakland / East Bay will provide needed service reliability and redundancy. It improves train operation and service by better connecting BART and Regional Rail networks, increasing train frequency, and providing enhanced or new stations in communities that are not served by trains today. Link21 will benefits riders and communities near the crossing and throughout the Megaregion.

Focusing on Today, While Planning for the Future

As we continue to recover post-pandemic, Link21 is working to better understand community needs that have access to rail today, and those who could benefit from service in the future. This understanding is helping the Program to identify service improvements and the needed infrastructure to achieve desired service. Stakeholder and public input, along with technical studies are helping to guide the development and refinement of service and concepts that will offer travel solutions for generations to come.

Equitable engagement creates opportunities to garner understanding of community experience, resident sentiments, and knowledge from those who have lived experience with transportation and infrastructure inequities.
