Car enters Muni tunnel to halt Market Street subway service across San Francisco
San Francisco transit officials were forced to suspend Market Street subway operations overnight after an unauthorized passenger vehicle drove down an entrance ramp and traveled hundreds of feet into the Muni underground tunnel network. The bizarre incident occurred near the downtown portal, where the sedan bypassed security markers, rolled onto specialized rail trackbeds, and ultimately became high-centered on the steel rails, entirely paralyzing electric light-rail transit through the central subterranean artery. Transit security personnel and San Francisco Police Department officers arrived rapidly, detaining the driver at the scene while safety crews evaluated the track infrastructure for structural damage.
The immediate closure caused extensive disruptions across the municipal transportation grid, forcing Muni operators to deploy emergency bus shuttles along surface corridors to accommodate thousands of late-night commuters and weekend riders. Overhead electrical catenary power had to be entirely de-energized along the tunnel section to allow heavy-duty tow trucks, specialized rail maintenance cranes, and municipal engineering crews to extract the trapped automobile safely without damaging signaling equipment. Maintenance personnel carefully inspected track alignment, switch machinery, and third-rail safety mechanisms throughout the night to ensure no subtle fractures or track misalignments had been caused by the vehicular incursion.
Muni transit executives confirmed that normal subway train operations were successfully restored by morning service following rigorous safety verifications, but the event has rekindled sharp criticism regarding portal physical security. Commuter advocacy groups and municipal oversight boards have repeatedly demanded that transportation authorities install automated rising bollards, physical crash gates, or enhanced sensory alarms to prevent errant automobiles from accessing open transit tunnels. City leaders announced that transit safety engineers will review the current physical defenses at all downtown rail portals to implement preventative structural upgrades and prevent future subterranean traffic disruptions.
