Get Valley Linked!

The Tri-Valley – San Joaquin Valley Regional Rail Authority is undertaking preliminary engineering and environmental review for the Valley Link Rail Project.  The Proposed Project would establish a new passenger rail service along a 26-mile corridor linking the existing Dublin/Pleasanton Bay Area Rapid Transit (BART) Station in Alameda County and the Mountain House community in San Joaquin County with all-day service at frequent intervals in both directions using zero-emission rail vehicles.

The alignment would be constructed within a combination of an existing freeway median (along I-580), an existing transportation corridor owned by Alameda County, and new right-of-way in San Joaquin County, terminating at the Mountain House community. The Proposed Project includes four new stations, an Operations and Maintenance Facility (OMF), and an Operations Support Site.

California Environmental Quality Act (CEQA) Scoping to Begin Fall / Winter 2022 

The Tri-Valley – San Joaquin Valley Regional Rail Authority (Authority) as Lead Agency is preparing a Subsequent Environmental Impact Report (EIR) for the proposed Valley Link Rail Project, consistent with requirements under the California Environmental Quality Act (CEQA). As further described below, the purpose of the Subsequent EIR is to analyze the potential environmental effects associated with revisions to the previously analyzed improvements included in the Valley Link Rail Project Final EIR approved by the Authority in 2021. As such, the Authority has published a Notice of Preparation (NOP) for the Project. View the NOP here

The Authority will hold two virtual public scoping meetings to provide an informal opportunity for attendees to receive information and ask questions about the Proposed Project. The meetings will be held on:

  • Monday, December 5, 2022, from 6:30-8:00 PM

  • Tuesday, December 6, 2022, from 11:30 AM-1:00 PM

The public scoping period for this project will be open from November 14 until December 19, 2022. Click here to learn more about how to submit scoping comments.


On May 12, 2021, the Authority Board approved a staff-recommended CEQA Certified Alternative, as published in the Valley Link Rail Project Final Environmental Impact Report (EIR). The CEQA Certified Alternative included an initial operating segment (IOS) that would establish initial service from the Dublin/Pleasanton BART Station to the Mountain House Alternative shown in the map below.

The Mountain House Station Alternative IOS is the basis of the Proposed Project to be evaluated in the present Subsequent EIR.

Subsequent to the approval of the Final EIR in 2021, the Authority has advanced design and analysis of the Mountain House Station Alternative IOS from the existing Dublin/Pleasanton BART Station to include a new alignment that responds to requests by the community of Mountain House for a Valley Link station that better serves their community. This new alignment would reduce construction cost, improve travel time through a straightened alignment, enable improved station access, and facilitate the advancement of transit-oriented development.


The proposed changes to the 2021 CEQA Certified Alternative IOS, now constituting the Proposed Project, include locating the Dublin/Pleasanton Station platform to the south side of I-580 (rather than in the freeway median), realignment of the trackway in the Altamont Pass, a new Mountain House Community Station and Operations and Maintenance Facility (OMF), and construction of an Operations Support Site in Tracy. The Mountain Community House Station would be constructed north of I-205 on a site west of Mountain House Parkway near the I-205/Mountain House Parkway interchange. The new OMF would be constructed on a site east of Mountain House Parkway and north of I-205.


The Proposed Project will be further refined and analyzed through the preliminary engineering and environmental analysis process, and does not preclude the possibility of extending service along an alignment to serve a potential future Downtown Tracy Station.
