California announced $750 million for The Portal on Nov. 10, advancing a plan to take Caltrain past its San Francisco terminus at Fourth and King streets. The 2.2-mile project would add an underground station at Fourth and Townsend and bring trains into the space already built for them beneath the Salesforce Transit Center, where California high-speed rail is also planned to end.
The award has two parts. The California State Transportation Agency’s project summary lists $100 million in this round and $650 million under a multiyear funding agreement. The Transbay Joint Powers Authority, which leads the project, says the $100 million will advance preconstruction work. The authority says the $650 million is for construction. That puts about 87 percent of the announced state award in the multiyear portion. The $750 million is the total announced award; the summary does not say that sum has been paid out.
There is also a federal condition. The state summary flags a Full Funding Grant Agreement contingency tied to the Federal Transit Administration’s New Starts program. The authority describes roughly $3.38 billion in federal money as committed. The FTA dashboard, updated Nov. 5, still lists the project in engineering with a $3.384 billion federal request and an estimated grant date of summer 2027. That estimate refers to the grant, not to when trains would run downtown.
The two records also put different prices on the project: about $7.57 billion in the state award summary and about $8.25 billion in the federal dashboard. Those figures come from separate records; neither gives readers a basis to treat the state award as a fully funded construction plan. The next funding milestone to watch is a signed federal grant agreement. For riders, the change to look for later is a Caltrain schedule that actually lists the downtown stop.
