A southbound Caltrain struck a car near the Broadway at-grade crossing on Wednesday evening, Sept. 2, delaying rush-hour service for more than an hour across the Peninsula.

No serious injuries were reported, according to Patch.

The collision halted the southbound train during the evening commute, backing up service at stations from San Francisco southward, according to a San Francisco Chronicle post on Facebook.

The Union Star also reported that riders faced major delays. Neither Caltrain nor the Burlingame Police Department had released an official statement about the incident as of Thursday morning.

The crash happened at the same crossing that the San Mateo County Transportation Authority (SMCTA) has called the highest priority rail grade separation in the state. The Broadway Grade Separation Project, now in its final design phase, aims to eliminate the at-grade crossing entirely by replacing it with a grade-separated rail corridor.

In June 2026, the SMCTA Board of Directors approved more than $340 million in Measure A sales tax funding for the project's final design and construction. Belmont Mayor Julia Mates, the board's chairperson, said in June when the board approved the funding that "improving safety at rail crossings remains one of the most important transportation investments we can make for our communities."

The project underwent a value-engineering redesign approved by the Burlingame City Council in May 2025, shifting the track eastward with a narrower elevated guideway, according to Caltrain's quarterly capital project report. That report describes the redesign as permanently eliminating the existing Broadway Caltrain Station — though SMCTA's own grade separation program page describes the project as including a new Broadway station with updated amenities, and a separate account of the funding vote described the work as demolishing and reconfiguring the station rather than removing it outright. The discrepancy was unresolved as of this report. The plan also calls for two pedestrian undercrossings north of Morrell Avenue and integrated bike and pedestrian pathways.

As of that report, covering January through March 2026, the project was in its 65% design phase. The milestone was forecast for completion by July 7, 2026. The estimated completion date for the full project is Sept. 5, 2033.

In February 2026, the SMCTA Board adopted new policies allowing Burlingame's project to claim a majority of remaining Measure A and W funding through the life of each measure, according to the authority's grade separation program page. The project's current design phase has about $43.1 million in activated funding.

Caltrain's 2026 Corridor Crossing Strategy places the Broadway crossing in its highest priority tier for safety enhancement and elimination. Construction timelines and any remaining funding gaps have not been publicly updated since the first-quarter report. Residents who witnessed Wednesday's collision or have safety concerns can contact the Burlingame Police Department's non-emergency line or report issues to Caltrain through its website.
