In 2012, a southbound Baby Bullet express train passing through the station narrowly avoided striking passengers for a northbound train stopped at South San Francisco. The Baby Bullet express did not have a scheduled stop at the station and had ignored the hold-out rule.South San Francisco is the only hold-out rule station with regular service on weekdays: two (Atherton and Broadway) are served only on weekends; one (College Park) has only limited service, with two round-trip stops per weekday serving the nearby Bellarmine Prep; and one (Stanford) is only served on Stanford's home football game days. As such, the South San Francisco station is a bottleneck.
