The mother was stopped between the crossing gates in heavy traffic, police said.

"It's horrible, it's tragic, but hopefully it's a wake-up call for other people to not stop on the tracks," San Leandro Police Lt. Robert McManus told InsideEdition.com.

Apparently, Henriquez was stuck in a long line-up of cars and was straddling the tracks when the gates came down.

Police and paramedics responding to the collision found the woman and child inside the vehicle, which was trapped under the front rail car.

None of the 39 passengers onboard the Amtrak train bound for San Jose were injured, a rail spokeswoman said.

Trains along that Northern California route can reach a maximum speed of 79 mph.

Henriquez was a stay-at-home mom who doted on her two children, a relative told a local television station. She had been on her way to pick up her eight-year-old son when she was hit by the train.
