A person is dead after being hit by a Sprinter train in the Vista area Monday evening -- the third fatal pedestrian incident on San Diego County's rail system in the past week.

The crash happened around 8 p.m. near the intersection of Santa Fe Avenue and Woodland Drive.

The San Diego County Sheriff's Department confirmed the victim has died, and the Sprinter service was delayed about one hour between Buena Creek and Civic Center Vista, according to the North County Transit District.

A Sig Alert was also issued on Santa Fe Avenue for 90 minutes as sheriff's detectives investigated the crash.

Early Saturday morning, a 40-year-old man died after being hit by a freight train in Encinitas. That incident was nearly 24 hours after a 22-year-old man was struck and killed by the same type of train in Carlsbad.
