s CASTLE ROCK, Wash. - A southbound Amtrak train collided Monday with a Honda Accord and four people died, a BNSF Railway spokesman said. One person was found dead inside the car and an initial investigation indicated three people were ejected in the 4:40 p.m. crash, spokesman Gus Melonas said. The collision, about four miles north of here, claimed the lives of an adult woman driver, a 17-year-old woman and two young men, who were 18 and 19, Melonas said. The rail crossing, at a point where a county road ends and a private road begins, was marked by stop signs, he said, adding the engineer tried to brake and sounded the train's whistle. The circumstances of the accident were under investigation by Cowlitz County sheriff's officers and BNSF Railway, which owns the tracks. No one aboard the passenger train was injured, Melonas said. The accident temporarily shut down BNSF's double main line that carries 60 trains daily between Seattle and Portland, Ore., he said. The 14-car, two-locomotive train carrying 123 passengers was en route to Portland.
