RICHLAND, Wash. (AP) — Authorities say eight train cars carrying corn derailed in Richland near the Yakima River train bridge. The Tri-City Herald reports firefighters were called to the area just after 4 p.m. Friday when the BNSF rail cars went off the track. BNSF is investigating what caused the cars to derail. Local streets were closed while crews cleared the area. BNSF spokeswoman Courtney Wallace says most of the train was moved from the area by Saturday morning. Crews were working Saturday to clean up the spilled corn. No one was hurt.
