Overview
- SFMTA concluded a weeks-long investigation into the Sept. 24 N‑Judah run that accelerated to about 50 mph exiting the Sunset Tunnel near Duboce Park.
- The train skipped the Duboce Avenue and Noe Street stop, then halted near Walter Street without derailing, according to the agency.
- Video circulated by local outlets appears to show the operator nodding off as passengers were jolted, with at least one rider later treated for a concussion.
- Officials said the braking system and related infrastructure were inspected and found no faults, with equipment performing as designed.
- Under agency protocols the operator was placed on non‑driving status, and SFMTA is reinforcing fatigue training and working with Siemens on software to limit speeds at specific locations.
