San José to Merced

The San José to Merced project section of the California high-speed rail system will provide a critical rail link between Silicon Valley and the Central Valley. The project section runs from San José (Diridon Station) to Gilroy, then (after passing through the Central Valley Wye) north to Merced or south to Fresno.

The focus of the San José to Merced project section is the area between San José and the Central Valley Wye. The Central Valley Wye is being developed as part of the Merced to Fresno project section.

This route will run from Diridon Station in downtown San José, through the Pacheco Pass, to the western limits of the Central Valley Wye, approximately nine miles northeast of Los Banos in Merced County.

The Authority is working to environmentally clear the section between San José and the Central Valley Wye. Options range from a new dedicated high-speed rail corridor between San José and Gilroy to a shared corridor with electrified Caltrain service using the existing rail corridor.

Public Involvement & Community Outreach

High-speed rail is our opportunity to modernize the Bay Area’s transportation system and leave a positive environmental legacy for our children and grandchildren. The Authority encourages public engagement in California high-speed rail construction and operations, so that the final project reflects the needs and vision of our community as a whole.

We conduct outreach events throughout Northern California, such as Open Houses and Community Working Group meetings, to inform and gather input from local communities, policymakers, and stakeholders. Stakeholders include environmental justice groups, community organizations, city/county staff, neighborhood groups, and California residents.

Below is a list of open houses and working group meetings conducted since the fall of 2019. For a listing of upcoming events and outreach opportunities in your area, visit the Events page. Meeting materials prior to June 2019 can be requested through a Public Records Act request.
