Terrifying Moment Train Conductor Nods Off at 50 MPH — Riders Slammed to the Floor as Cars Nearly Hit

Passengers aboard a San Francisco Muni train were left screaming in terror after their conductor apparently fell asleep — sending the two-car train hurtling through a tunnel at more than 50 mph and nearly colliding with a passing vehicle.

The horrifying moment, caught on video and obtained by KRON4, shows the female driver slumped over in her seat as the train barrels into a sharp curve inside the Sunset Tunnel near Duboce Park.

Within seconds, the packed cabin lurches violently. Passengers are thrown sideways, tumbling over one another as the train whips through the turn. “I wanna get off!” one woman shrieks. Another can be heard crying out, “Oh my God!”

Moments later, the jolt apparently wakes the conductor. The footage shows her snapping upright, frantically grabbing the controls and slowing the train to a stop.

“I’m sorry. Relax, relax, relax,” the shaken driver tells the panicked riders. “We didn’t crash. Relax.”

According to the San Francisco Chronicle, at least one woman suffered a concussion in the chaos and was treated on-site.

An initial investigation by the San Francisco Municipal Transportation Agency (SFMTA) confirmed the cause was “operator fatigue,” not mechanical failure.

“The train experienced a series of unexpected jolting movements while navigating a curve at an excessive speed of 50 mph,” SFMTA said in a statement. Officials did not specify what the safe speed for that stretch normally is, but local transit experts said the limit is typically much lower.

Julie Kirschbaum, SFMTA’s director of transportation, called the incident “unacceptable” and promised swift accountability.

“We know this was a frightening experience for our riders, and we take that very seriously,” she said. “Safety is always our top priority. We are committed to ensuring this never happens again.”

The agency confirmed the operator has been placed on nondriving status pending disciplinary action and additional training.

Transit watchdogs say the near-disaster raises new concerns about overworked staff and outdated safety systems on Muni’s network.

“This could have been a catastrophe,” said transportation advocate Michael Toren of the Bay Area Riders Alliance. “It’s pure luck that no one was killed. Fatigue shouldn’t be a factor when you’re operating a multi-ton train through a city tunnel.”

The SFMTA says it will conduct a full review of operator schedules and safety procedures.

But for passengers who lived through the terrifying ride, the promise offers little comfort.

“I’ll never forget that sound — the metal screeching and people screaming,” said one passenger, still shaken weeks later. “We were just praying she’d wake up before it was too late.”
