Project Description

The Tri-Valley  - San Joaquin Valley Regional Rail Authority was established on January 1, 2018 through the enactment of Assembly Bill 758 with the mandate to plan and deliver cost-effective and responsive transit connectivity between the BART system in the Tri-Valley and the Altamont Commuter Express that meets the goals and objectives of the communities it will serve. It also required the completion of a Project Feasibility Report to outline how this could be achieved. The Final Report, adopted by the Board in October 2019, identifies a proposed project – now undergoing further design and environmental review:


Phase 1: Rail service from the existing Dublin/Pleasanton BART Station to the proposed North Lathrop/ACE Station, utilizing existing transportation rights-of-way where feasible.


Phase 2: Rail service extended from the North Lathrop ACE Station to the existing Stockton ACE/San Joaquin Stations.

Following is a summary of key elements of the proposed project:


Project Goals

  • Improve connectivity within the Northern California Megaregion: connecting housing, people, and jobs.

  • Rail connectivity between the San Francisco Bay Area Rapid Transit District’s rapid transit system and the Altamont Corridor Express commuter service in the Tri-Valley.

  • Project implementation that is fast, cost-effective and responsive to the goals and objectives of the communities it will serve.

  • Be a model of sustainability in the design, construction and operation of the system.

  • Support the vision of the California State Rail Plan to connect the Northern California Megaregion to the State rail system.


Proposed Stations and Facilities


  • Dublin/Pleasanton BART Intermodal

  • Isabel (Livermore)

  • Greenville ACE Intermodal (Livermore)

  • Mountain House

  • Downtown Tracy

  • River Islands (Lathrop)

  • North Lathrop ACE Intermodal

  • Stockton ACE/San Joaquins Intermodal

Infill Stations:

  • Southfront (Livermore)

  • Grant Line Road (Alameda County)

  • Ellis Historical (Tracy)

Operations and Maintenance Facility:

Hansen Road (San Joaquin County)


System Integration/Connectivity

  • Seamless transfers to BART and ACE

  • Integrated fare systems

  • Expand and improve connectivity through improved transit and/or feeder bus services.

  • Integrate rail services with state’s rail and transit operations (including High Speed Rail System).


Service Characteristics

Regular service throughout the day in both directions with the ultimate goal of matching BART hours of operation and frequency.


Vehicle Technology

  • Multiple unit (MU) trains featuring hybrid technology, with the ability to convert to fully-electric operations in the future.

  • Consideration of technology advances - full electric battery operation and potential use of hydrogen fuel cells to power train motors.



Be a model of sustainability in design, construction and operation of the Valley Link Rail Project:

  • Reduce greenhouse gas (GHG) emissions

  • Renewable energy – Operate system on renewable energy to extent feasible

  • 100 percent self-sufficient – Strive to create a system that can operate largely on its own stored and created energy

  • Design and construct sustainable infrastructure using global best practices for preserving natural resources.


Equitable Access

  • Encourage engagement in planning and decision-making for the project to ensure a meaningful level of participation from disadvantaged communities and low-income communities and households.

  • Strive to maximize benefits to disadvantaged communities and low-income communities and households in project planning and design.


Station Area Planning

  • Initiate service at earliest possible date and preserve land and right-of-way to allow for the implementation of phased design and infrastructure in support of Sustainable Community Strategies (Senate Bill 375).

  • Work in partnership with communities to identify and incorporate high priority local goals and objectives for individual stations.

  • Promote active transportation (bicycling and walking).

  • Encourage use of zero emission vehicles and shared rides.
