Link21 Partner Agencies

Link21 Sponsors

Link21 is sponsored by the San Francisco Bay Area Rapid Transit (BART) and the Capitol Corridor Joint Powers Authority (Capitol Corridor).

BART and Capitol Corridor have secured partial funding to support planning and analyses. Estimates of the overall project costs are being developed and program concepts are being defined and developed. BART and Capitol Corridor are collaborating with partner agencies, jurisdictions, and stakeholders on Link21. 


For more than 45 years, BART has provided fast, reliable transportation to work, shopping, tourist attractions, entertainment, airports, schools, and other destinations for Bay Area residents and visitors alike. 

BART connects the San Francisco Peninsula with communities in the East Bay and South Bay. BART service currently extends as far as Millbrae, Richmond, Antioch, Dublin/Pleasanton, and Berryessa/North San Jose. Every day, BART serves people from 14 counties in the 21-county Northern California Megaregion.

Capitol Corridor

The Capitol Corridor Joint Powers Authority oversees the Capitol Corridor, a passenger train system that provides fast, reliable intercity rail service along a 170-mile route to 18 stations in eight Northern California counties: Placer, Sacramento, Yolo, Solano, Contra Costa, Alameda, San Francisco, and Santa Clara. 

Prior to COVID-19, Capitol Corridor had the second highest ridership of all Amtrak-operated state-supported routes, second only to the Pacific Surfliner. 

Capitol Corridor is a partnership among six local transit agencies that share the administration and management of the rail system. BART provides day-to-day management support to Capitol Corridor.

Link21 Program Committees

BART and Capitol Corridor have established the following standing committees to help guide the Link21 Program. In addition to these groups, the Link21 Team meets frequently with additional agencies, jurisdictions, and other stakeholders.

Link21 Program Development Team

The Link21 Program Development Team (PDT) consists of Regional Rail operators, as well as transportation planning and funding agency partners. They are helping to shape Link21 by offering feedback on technical aspects of the Program. Senior staff from the Link21 PDT agencies meet regularly. The group is expected to expand as Link21 develops.

Link21 Executive Program Development Team

The Link21 Executive PDT consists of the executive staff from the same agencies that are represented on the Link21 PDT. This group meets biannually and/or at major milestones.

Jurisdictional Working Group

The Jurisdictional Working Group (JWG) consists of city and jurisdictional partners who provide input to the Link21 Program with a particular focus on local issues, such as stations and land use. The JWG consists of cities likely to be included in the new transbay passenger rail crossing project. As Link21 evolves, new members will be added to the JWG. This group meets quarterly or at major milestones.

Future Committees

BART and Capitol Corridor expect to establish committees in the future that focus on equity and regulations. As Link21 moves forward, BART and Capitol Corridor will work with stakeholders to identify the need for additional committees.
