Two bodies, a man's and a woman's, were found on Wednesday near Kibbutz Ma'agan Michael.
The police began an investigation as to whether the two were the survivors of Tuesday's accident in which a train collided into a car that was laying on the train tracks.
A third woman, 82, was presumed to be the deceased's wife. She survived the wreck and was hospitalized in serious condition. The police could not question her because of her medical condition.
The initial findings suggested that they were a man and his daughter who escaped the accident. They apparently climbed a nearby electrical pole, and were electrocuted, Israel Radio reported.
