Caltrain has spent the past two years selling the most successful turnaround in Bay Area transit: electric trains, faster trips, half-hourly service seven days a week, and ridership growth that the agency says made it the fastest-growing transit system in the country. On Tuesday, it will show Santa Clara County’s Board of Supervisors the other side of the ledger.

Item 10 on the board’s Oct. 20 agenda, placed by board President Otto Lee, is a presentation on Caltrain’s “No External Funding Scenario,” the contingency plan the railroad adopted in June for a future without the regional transit sales tax on the Nov. 3 ballot, Measure RTM, which Caltrain and its backers call Connect Bay Area. Caltrain “continues to face a structural operating funding gap beginning in Fiscal Year 2028 absent a new, ongoing external revenue source,” Lee’s memo says, and the cost cutting, ridership gains and one-time bridge funding so far “are insufficient to sustain existing levels of service over the long term.”

This analysis draws on the 24-slide presentation Caltrain prepared for the board, the framework deck and minutes from the June 4 meeting of the Peninsula Corridor Joint Powers Board, the railroad’s governing body, and the measure’s legal text.

The $75 million hole

Caltrain’s problem is structural and, by its own account, not of its own making. In 2019, fares made up more than 70% of operating revenue, about $100 million, according to the June deck. Fares now cover about 30%, roughly $43 million. The agency lists four causes: lasting changes in commute patterns since the pandemic; fewer riders, meaning less fare, parking, rental and advertising income; operating costs rising faster than revenue across the transit industry; and 51 miles of new 25-kilovolt electrical infrastructure to maintain. Member-agency contributions have ended and one-time pandemic funds are exhausted. The result, the deck says, is “a structural operating deficit that cannot be resolved through cuts or self-generated revenue alone.”

For fiscal 2028 and beyond, Caltrain projects an average operating deficit of $75 million a year over the next 15 years. The board adopted a fiscal 2027 operating budget of $269 million with a $47.6 million deficit, closed with a one-time state loan, according to the June 4 minutes.

The railroad has cut where it says it can. Staff reported $76 million in cost savings since 2020, the minutes say, and the presentation to supervisors cites a hiring freeze, crew scheduling efficiencies, a line-by-line budget review, recovery of regenerative-braking energy, and a Metropolitan Transportation Commission study on cost containment identifying “$70M in savings.” But like all rail operators, Caltrain says, about 70% of its costs are fixed.

What ‘no external funding’ looks like

The presentation lays out what Caltrain would consider, starting in fiscal 2028, if no new money arrives:

  • Hourly trains all day on weekdays, down from every 15 minutes at peak and every 30 minutes off-peak.
  • No weekend service, eliminating all Saturday and Sunday trains.
  • Closing more than one-third of all stations.
  • Ending operations by 9 p.m., instead of running from about 5 a.m. to about 1 a.m.
  • Eliminating special-event trains for games and concerts.
  • Cutting segments of service and significant administrative costs.

Under the timeline in the June deck, Caltrain would return in January 2027 with a preliminary fiscal 2028 budget and begin a six-month process to ramp down service, with significant cuts starting in summer 2027 after that budget is adopted.

The slide that will draw the most attention goes further. “If no external funding, passenger service could stop and focus exclusively on maintenance and safety of the corridor and assets,” it reads. “Once shut down, minimum 2-4 years to resume Caltrain passenger service.” In June, board discussion described a full shutdown as “a possible but unlikely extreme scenario due to high fixed costs,” the minutes say. The presentation also cautions that “specific cuts are not certain yet,” and Caltrain’s budget page notes that station closures would require further analysis, including of ridership and equity.

The downward spiral

Caltrain’s central argument is that cuts don’t solve the problem. Reduced frequency and hours deliver most of the savings, but the agency projects they would reduce ridership by 60% to 70%, cutting fare, parking, advertising and leasing revenue in turn. “Cutting service drives away riders, reducing operating revenue in a downward spiral, offsetting much of the savings from cuts,” the deck says. “Significant deficit remains.” It adds that cuts at other agencies “would increase Caltrain’s ridership loss.”

That is the context for the numbers Caltrain wants supervisors to weigh: 77 miles, 31 stations across 20 communities, ridership growth of more than 25% year over year since electrification, more than 500,000 $1 youth fares in 2026, on-time performance above 95%, and a rider base that is 37% low-income. The June deck adds that 51% of riders have no access to a car for their trip and that Caltrain carries the equivalent of about three freeway lanes at peak.

What Measure RTM would send Caltrain

Measure RTM, authorized by Senate Bill 63 in October 2025, is a citizens’ initiative that, according to Caltrain’s budget page, would “fully address Caltrain’s operating deficit for 14 years” if approved by a majority of voters. The tax would run from April 1, 2027, to April 1, 2041, according to the GrowSF voter guide, which supports the measure.

Caltrain’s share is written into the measure as percentages of revenue raised in each county: 3.97% of San Francisco’s revenue, 24.07% of San Mateo County’s and 10.38% of Santa Clara County’s, according to the legal text as published by GrowSF. Most of Santa Clara County’s revenue, 84.37%, would go to the Valley Transportation Authority for transit and repaving on roads served by fixed-route transit.

The shares follow a split Caltrain’s board took up in July 2025. After Sens. Scott Wiener and Jesse Arreguín proposed “7% or $75M for Caltrain,” Caltrain staff presented allocation terms, unanimously supported by a board ad hoc committee, setting a funding target of about $75 million a year, split approximately $32.5 million from Santa Clara County, $32.5 million from San Mateo County and $10 million from San Francisco, according to the July 23, 2025, staff presentation. GrowSF estimates Caltrain’s yield under the final percentages at about $69 million a year. Whether the measure closes the gap in every year will depend on actual sales tax receipts; Caltrain says it would fully address the deficit.

The measure needs a simple majority across the five-county district. In the Joint Venture Silicon Valley poll, 48% of Bay Area respondents favored it, 34% opposed and 18% were unsure, as we reported today.

Why Santa Clara County supervisors are hearing it

The county board does not govern Caltrain; the Joint Powers Board, with members from San Francisco, San Mateo and Santa Clara counties, does. Supervisors’ role in Tuesday’s item is to “receive” the report. But the presentation is pitched at local officials: slides on Go Pass programs, “Destination Downtown” partnerships with cities, Diridon Station planning, and ridership trends by city. It also follows a broader pattern. If RTM fails, Caltrain’s cuts would not happen in isolation, because the deck explicitly flags “contemplated cuts to other agencies.” GrowSF, which backs the measure, says BART faces a $378 million deficit and would cut train hours by 63% starting in January 2027 without new funding. For San José, where the BART extension downtown is still underground and years away, Diridon’s future as a regional hub depends on Caltrain running frequent service.

The long view

Caltrain’s crisis is a case study in a transit financing model built for a 2019 commute. A railroad that once covered most of its costs from fares invested heavily in electrification, delivered the service riders asked for, and saw ridership climb, yet still faces a deficit because office commuting, the base of its fare revenue, has not returned to its old pattern.

Measure RTM is the region’s answer for the next 14 years, not a permanent one. If it passes, the 2041 expiration becomes the next cliff, and under Proposition 43, if voters approve that measure too, any renewal by citizen initiative would need two-thirds support, as we explained today. If RTM fails, Caltrain has already written down what comes next, and Tuesday’s presentation puts it on the public record in the county with the most at stake.
