The Tri-Valley–San Joaquin Valley Regional Rail Authority Board approved the Project Feasibility Report for Valley Link, a rail service envisioned to conveniently connect San Joaquin Valley communities and Livermore with the Dublin/Pleasanton BART Station, including connections with the ACE rail system.

Phase 1 of the proposed Valley Link rail service would cover 41 miles connecting the existing Dublin/Pleasanton BART Station to the proposed ACE North Lathrop Station using hybrid train technology. A second phase would extend service from the North Lathrop Station to the ACE and Amtrak Stockton Station.

Other proposed station locations in Phase 1 include: Isabel Station; Greenville ACE Intermodal Station; Mountain House Station; Downtown Tracy Station; and River Islands Station. Initial service is proposed to operate from 5 a.m. to 8 p.m., with service every 12 minutes between the Dublin/Pleasanton BART Station and Greenville Road during peak hours and every 24 minutes beyond Greenville to the North Lathrop Station. Trains would be scheduled to allow for convenient transfers to BART. The first Valley Link trains could be placed in service as early as 2027.
