A pedestrian was struck and killed by a Caltrain early Wednesday morning in Redwood City, causing major delays as the agency responded.

At about 8 a.m., Caltrain officials reported that both tracks had been reopened in the area, allowing the system to recover.

The incident, involving an adult female trespasser on the tracks, occurred at 6:15 a.m. on the northbound 305 train at Whipple Avenue in Redwood City and prompted delays up to 90 minutes, Caltrain said.

The incident appeared to be a suicide, officials said.

Trains were single-tracking in the area for more than an hour, first at maximum speeds of 10 mph and later at maximum speeds of 50 mph, before both tracks reopened.
