Link21 Partner Agencies

Link21 Implementing Agencies

As two of the major rail service providers in the Northern California Megaregion, the San Francisco Bay Area Rapid Transit (BART) and the Capitol Corridor Joint Powers Authority (Capitol Corridor) have partnered to advance Link21.  

BART and Capitol Corridor have secured partial funding to support planning and analyses. Estimates of the overall project costs are being developed and refined program alternatives 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 throughout Northern California.

Capitol Corridor

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

Capitol Corridor has 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 CCJPA 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 consists of Regional Rail operators, 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 program development team agencies meet quarterly. The group is expected to expand as the Link21 Program develops.

Executive Link21 Program Development Team

The Link21 Executive Program Development Team comprises the executive staff of the same agencies that are represented on the Program Development Team and meets biannually and/or at major milestones.

Jurisdiction Working Group

The Jurisdiction Working Group consists of city and jurisdictional partners who provide input to the Link21 Program, with a particular focus on local issues related to the Program, such as stations and land use. The Jurisdiction Working Group currently comprises cities likely to be included in potential new transbay rail crossing alternatives. As Link21 evolves, new members will be added to the Jurisdiction Working Group. 

Future Committees

BART and CCJPA anticipate convening committees in the future, one on equity and another on regulations. As Link21 advances, BART and CCJPA will work with stakeholders to identify the need for additional committees.
