In Northern California, high-speed rail will run from San Francisco to Gilroy, sharing tracks with electrified Caltrain service before turning east through Pacheco Pass to connect to Merced County. The Authority completed environmental clearance for the entire Northern California alignment in 2022 and is preparing for advanced design as funding becomes available. The Authority is actively seeking additional funding to progress design work and begin critical geotechnical studies in the Pacheco Pass, a key step for linking to the Central Valley. In the meantime, the Authority is working closely with regional partners to deliver joint benefits projects aimed at modern, integrated and seamless connections with high-speed rail, such as Caltrain Electrification, The Portal, and a modern Diridon Station in San Jose.
Current Status of Northern California Section
Alignment & Stations
The Northern California section will have stations in San Francisco, Millbrae, San José, and Gilroy with direct connections to over a dozen
different transit providers serving all parts of the Bay Area. The alignment between San Francisco and Los Angeles gained environmental approval in Spring 2024.
The Authority continues to work with local partners to develop station area plans based around proposed high‑speed rail centers.

San Francisco rau San José
51 miles
Between San Francisco and San José, high-speed rail will use the existing Caltrain corridor. The California High-Speed Rail Authority (Authority) invested about 1/3rd of the cost of Caltrain’s Electrification Project, which was completed in 2024. Additional high-speed rail upgrades in the corridor will include modifications at existing stations, a light maintenance facility, and upgrades to improve safety and speed along the corridor. The modern system brings high-speed rail infrastructure to the Peninsula which will allow for both operators to share tracks in a blended system. The service will ultimately run to the Salesforce Transit Center once it is connected to the existing rail corridor via The Portal Project, replacing Caltrain’s 4th and King Station as the northern terminus for electric and high-speed trains.
Status:
- San Francisco to San Jose was environmentally approved in 2022.
- Electrification of the Caltrain corridor is complete. Passenger service started in September 2024.
- The Salesforce Transit Center opened in August 2018 and a train box has already been excavated below ground.
- In Spring 2024, the Transbay Joint Powers Authority, received a $3.4 billion dollar federal commitment for The Portal Project. Also known as the Downtown Rail Extension project, The Portal Project will extend Caltrain’s rail system to the multimodal Salesforce Transit Center in downtown San Francisco and ultimately bring the statewide California High-Speed Rail system into its northern terminus, connecting 11 transit systems in the Bay Area. The federal commitment brings The Portal to over two-thirds funded.
San José los Merced
88 miles
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 San José to Merced project section overlaps with the San Francisco to San José project section to the north and the Central Hav Wye project section to the east. This route will run from the city of Santa Clara, through Diridon Station in downtown San José to Gilroy, across the Pacheco Pass, to the western limits of the Central Valley Wye, approximately nine miles northeast of Los Banos in Merced County. The Authority Board of Directors adopted the Final EIR/EIS in April 2022, selecting a preferred alignment that will modernize and electrify the existing rail corridor between San Jose and Gilroy, allowing for both electrified high-speed rail and Caltrain service. East of Gilroy, the alignment includes more than 15 miles of tunnels through the Pacheco Pass in the Diablo Mountain Range.
Status:
- San Jose to Merced gained environmental approval in 2022.
- Key next steps include identifying funding for advanced design and beginning geotechnical investigations in Pacheco Pass.

Common NorCal Questions
Here are some of the most frequently asked questions we receive specific to the Northern California region of the California High-Speed Rail System.
Is high-speed rail coming to Northern California?
Yes, we’re working on it! The Northern California alignment is 100% environmentally cleared and the Authority is actively seeking funding to progress design work and begin critical geotechnical studies in the Pacheco Pass, a key step for linking to the Central Valley, where 119 miles of construction is underway. In the meantime, key partnerships and investments have already brought high-speed rail infrastructure to the Bay Area. The Authority invested $714 million into the Caltrain Electrification Project, which will facilitate blended service with high-speed rail and electric Caltrain trains using the same infrastructure. A train box under the Salesforce Transit Center in San Francisco has already been built by the Transbay Joint Powers Authority to serve as the future terminus of both Caltrain and high-speed trains as part of the Portal Project. These building blocks will all be connected to provide rail service between the Bay Area and the rest of the state.
I’m a Bay Area resident, when can I ride California High-Speed Rail?
By 2030-2033, at the earliest. Bay Area riders can take the Amtrak San Joaquin from Oakland or the Altamont Corridor Express service from San Jose and other East Bay locations to connect to Merced, where California’s High-Speed Rail initial operating segment begins. Extensive partnerships are in place to ensure these future connections provide seamlessly timed rail-to-rail transfers. A timeline for direct high-speed rail service from the Bay Area to Central Valley and Los Angeles cannot be established until funding is secured. The authority is actively seeking funding to advance project design toward construction in Northern California. Like most large projects, the California High-Speed Rail system is being built in phases.
What construction has been done in Northern California?
Within the Bay Area, the Authority is a partner on various projects, including Caltrain’s Electrification. This project is important as it will be used by high-speed trains that will share the tracks with Caltrain as a blended service corridor. Additionally, the Authority partnered with the City of San Mateo, San Mateo County and Caltrain on the 25th Avenue Grade Separation, which was completed in 2021.
What are we doing to address equity in Northern California?
The project has created more than 13,000 labor jobs since construction began in 2015. In the Northern California region, 289 certified small businesses are working on the project, the most of any region in the state. In Silicon Valley and the Bay Area, the project has spurred $2.4 billion of economic impact and logged $910 million of labor income between July 2006-June 2023.
What’s next for high-speed rail in Northern California?
Once funding is secured, the next major milestone for high-speed rail in Northern California will be completing the geotechnical investigations and advanced design work that will be necessary to acquire right-of-way and begin the process of tunneling through the Pacheco Pass to connect to the Central Valley.
The Authority’s funding to date has included both state and federal funds as well as partnerships (such as Caltrain Electrification) where the Authority’s funds helped leverage other funding sources. While specific funds for construction in Northern California have not been identified yet, the Authority will continue to pursue the funds through competitive grant programs and other opportunities. For the latest on funding, please refer to the Authority’s Business Plan.
What rail lines will high-speed rail connect to in Northern California?
Hauv addition to connecting the major regions of California, the Authority seeks to connect to existing rail and transit services so that the system can be accessible from many different places. Saib cov NorCal Rail Connectivity Map.
How will Caltrain and California High-Speed Rail share tracks?
Caltrain and the Authority have electrified the Bay Area corridor, which will allow for both operators to share tracks in a blended system. The service will ultimately run to the Salesforce Transit Center once it is connected to the existing rail corridor, replacing Caltrain’s 4th and King Station as the northern terminus for high-speed rail trains.
How will high-speed rail mitigate impacts to wildlife in the Bay Area, Gilroy, and Merced?
The Authority’s goal is to limit, where feasible, the extent to which high-speed rail presents an additional barrier to an animal’s natural movement and improve movement where barriers currently exist. Wildlife movement areas such as Coyote Valley, Soap Lake Floodplain, Pacheco Pass, and the Grasslands Ecological Area are located along the Northern California alignment between San Francisco and Merced.
Coordination with local and regional conservation groups throughout the design and environmental review process provides valuable insight and on-the-ground knowledge to mitigate impacts on wildlife. A $3 million grant was awarded to study The Pacheco Pass wildlife overcrossing. Thanks to their collaboration with the Authority, the design of the rail system includes a variety of measures to facilitate wildlife movement and reduce/mitigate the impact of the rail corridor.
I’m a small business owner in Northern California, how can I work on high-speed rail?
The California High-Speed Rail Authority is committed to small, disabled, disadvantaged, and diverse businesses playing a major role in building the statewide high-speed rail project. This commitment will inspire business growth, job creation, and workforce development opportunities while building the vitality of California’s high-speed rail program.

Kev cuam tshuam nyiaj txiag
As construction progresses in the Central Valley in preparation for operations, Northern California’s economic impacts can be felt. Through the last fiscal year ending June 2023, the project has invested $11.2 billion in planning and construction statewide. Investment in Northern California has resulted in $2.14 billion in economic benefits. This has also generated $910 million in labor income in the region and over 9,000 job-years of employment.
Did you know?
A job-year is a measure of employment, the amount of labor equal to a year of full-time work. A job year can be completed by employees working full-time or part-time. For example, if two people worked part-time for six months each, that would be one job-year, or someone working for two years full-time would be two job-years of employment.
