Police say according to the train conductor, the 58-year-old didn't seem to hear his train coming.
"At this point, we don't believe it to be anything other than an accident," said Lt George Hernandez. "It appears she may have been trying to Cross the tracks or may have been walking along side it when she was hit from behind."
Investigators say there was another train headed the opposite direction in the opposite track. They think the woman may have been busy watching that train before crossing, she didn't notice the other one coming from behind.
There are signs warning pedestrians to stay off the tracks, but those signs are often ignored.
"We do have a crossing just up that way, which is how you're supposed to do it," said Lt George Hernandez. "But like any city or town, people try to cross the tracks wherever they can."
Burlington Northern Santa Fe is conducting their own investigation on the accident.
The Kings County coroner's office is working to notify the victim's family members before they release her identity.
