Meeting Tomorrow For Diridon Station Redevelopment, San Jose
BY: ANDREW NELSON 5:30 AM ON MAY 14, 2024
New project details have been revealed ahead of tomorrow’s meeting about expanding the Diridon Station in San Jose. The Valley Transit Authority’s Diridon Joint Policy Advisory Board will review three design options to accommodate increased Caltrain services, integrate High-Speed Rail, and connect to the future BART extension. As expected for an infrastructure project in the Bay Area, the costs are astronomical, ranging from $2.5 billion to $13 billion.
The station expansion is expected to facilitate future service increases, including triple the hourly Caltrain trips, double the Capitol Corridor trips and four High-Speed Rail trips per hour. The three alternatives include elevated train tracks, at-grade train tracks, or stacked train tracks. Mott MacDonald, a global engineering firm, is responsible for drafting the alternatives.
At-Grade
The cheapest option will keep the tracks at grade while coincidentally making the most significant changes to the area around the Diridion Station. While kept at its existing elevation, the historic brick train station will be set above a new cobblestone-clad ground level. The station will remain the landmark entrance leading into the concourse.
Stacked
The Stacked option is the second most expensive option, but it would still create a new ground-level floor to the historic station building. This second alternative would not impact the PG&E facility and historic building on the south edge of Diridon Station.
Elevated
The most expensive option, which the VTA expects to cost at least $13 billion at the moment, will elevate train tracks and retain the historic structure’s positioning. The elevated and at-grade alternatives will require modifications for the PG&E facility, while the elevated plans require the Caltrain Central Equipment Maintenance and Operations Facility, or CEMOF to be relocated.
