The Future of San José Diridon Station

Program Overview

In 2018, the City of San José and four partner agencies (Caltrain, VTA, California High-Speed Rail, and MTC) established a plan for the expansion and redesign of Diridon Station. Diridon Station needed improvements to integrate with planned land use in the City of San José downtown area, connect different transit systems, and accommodate future growth and ridership from electrified Caltrain, BART, and High-Speed Rail service (estimated to bring over 100,000 daily passengers to Diridon Station by 2040)! From this plan, the Diridon Station Program was born. To learn more, visit the Planning History page.

In 2025, the Business Case phase led to advancing an “at-grade” alternative (see images below). It also established the Diridon Station Program, which created the foundation for the current planning process.

The Diridon Station Program is a collection of proposed projects organized into two groups: Station Elements and Southern Roadway Projects. Station Elements are parts of the station that will be added or changed. Southern Roadway Projects will modify street crossings where Park Avenue, San Carlos Street, Auzerais Avenue, and West Virginia Street meet the train tracks. We are currently in the Environmental Phase. This focuses on looking at how changes to Diridon Station may affect the surrounding environment and exploring ways to address these effects.

Community Engagement

Community engagement has played a big role in the history of the Diridon Station Program. Public input will continue to guide how the Program is defined, studied, and reviewed. It will also impact future decisions during Technical Studies and Environmental Review. Key stakeholders include nearby neighborhoods, the Historic Working Group, and more.

GALLERY: ARTISTIC RENDERINGS OF THE FUTURE STATION and nearby roadways

Architectural rendering of Santa Clara Street featuring the improved Diridon Station with at-grade tracks. In the foreground, pedestrians—including someone using a wheelchair—walk along a paved sidewalk near a grocery storefront. A green-painted bike lane runs parallel to a multi-lane road where cars and buses travel, bordered by trees and street banners.

To the right, the Diridon Station design with at-grade tracks features visible passenger train cars. Pedestrians, cyclists, and families cross an improved Cahill Street and walk along paved pathways lined with leafy trees under a blue sky

Architectural rendering of a sunlit public plaza in front of the historic Diridon Station depot featuring large arched windows and a tile roof. A water fountain spray sits near a central pool, surrounded by leafy shade trees, outdoor café seating, and an American flag on a flagpole. In the background, the at-grade tracks shows passenger train cars connects to the main facility, while numerous pedestrians walk, relax, and socialize throughout the stone-paved plaza.

Architectural rendering of a roadway underpass at Auzerais Avenue with separate, grade-separated paths for pedestrians, cyclists, and motor vehicles. On the left, pedestrians walk on a concrete sidewalk, separated by a low barrier from a green-painted, two-way bicycle lane. To the right, automobiles travel in two directions along a paved road flanked by residential buildings, utility poles, and mature trees under a clear sky.

Street-level architectural rendering showing a multi-modal San Fernando Street leading toward Diridon Station with the at-grade tracks. In the foreground, a two-way green bike lane and wide sidewalk host cyclists and pedestrians. Modern high-rise housing and historic brick buildings line the street alongside trees, streetlights, and slow-moving cars.

Architectural rendering of an improved West Virginia Street with a dedicated pedestrian and bicycle underpass ramping downward alongside a surface street. A green two-way bike lane runs down the center of the ramp, bordered by a concrete pedestrian walkway and safety railings. The street above is lined with single-story homes, flowering trees, wooden utility poles, and pedestrians crossing at a painted crosswalk.
