The Solano-Napa North Bay Passenger Rail Feasibility Study assesses the potential for passenger rail service connecting Napa, Vallejo, Fairfield, and Suisun City through upgrades to existing freight rail infrastructure in the region. This study builds on decades of prior analysis of transportation improvements between Napa and Solano Counties, incorporating current study area conditions and updated travel data into the evaluation of future passenger rail service. Supported by this analysis, this study recommends a phased approach to advancing high capacity transit along the Napa-Vallejo corridor, anchored by a long-term passenger rail vision. Under this approach, near-term improvements focus on enhancing existing bus services between Napa and Vallejo to address current travel demand and grow transit ridership.

This study identifies a long-term passenger rail service concept consisting of hourly service between Napa and Vallejo, with timed connections to a state-supported East–West service between Novato, Fairfield, and Suisun City. This concept was selected based on its travel time performance, infrastructure requirements, and consistency with the California State Rail Plan (CSRP) vision for connected North Bay rail corridors.
