The crash happened around 2 a.m. Monday morning. Officials say the train was traveling 40 miles per hour when the collision happened. It is unclear what led to the collision, but authorities say one man and two women died at the scene. Another two people were taken to the hospital -- and one of those people later died.
"From what we can see and have investigated so far, all lighting equipment was active on the train. A horn was sounded prior to approaching the intersection, from there on out we're still looking into why the collision occurred and why the vehicle decided to go across the tracks," said Jose Nunez, California Highway Patrol.
Investigators say because it was a private crossing, there was no warning equipment installed. It's unknown if alcohol or drugs played a role in this fatal collision. The female driver was transported to a local hospital. Investigators plan to interview her later.
