Caltrain Gets $750 Million Boost for Long-Awaited Downtown SF Extension

Key Points:

• California has awarded $100 million for pre-construction work and committed $650 million over multiple years toward the long-planned 2.2-mile Caltrain extension into downtown San Francisco, known as The Portal, connecting Fourth and King streets to the Salesforce Transit Center.
• The state funding aims to leverage a proposed $3.38 billion federal contribution through the Federal Transit Administration’s Capital Investment Grants program, though the federal commitment is not yet finalized.
• The extension project includes a tunnel, a new station at Fourth and Townsend streets, and completion of the transit center's underground train box, designed to eventually accommodate California high-speed rail trains.
• The project, first proposed in 2014, has faced funding uncertainties and delays, with the latest cost estimate at approximately $7.57 billion and a target for construction readiness in 2029 and passenger service by December 2036.
• Additional transportation funding from California’s Transit and Intercity Rail Capital Program includes $25 million for BART station redevelopment in Berkeley, nearly $25 million for Marin Transit’s electric-bus facility, and various grants supporting pedestrian safety, rail capacity, and transit upgrades across the state.
