(Portland, OR) -- A construction worker was killed in a crash on Tuesday with a MAX train in East Portland. The Multnomah County Sheriff's Office says 61-year-old Anthony Davis, of Salem, was working for Moore Excavation near Southeast 141st and Burnside when he walked onto the tracks. The train's operator sounded the horn and used the emergency brake system but couldn't stop before hitting Davis. He wasn't in a pedestrian crosswalk. Davis died at the scene. Investigators don't know why he walked onto the tracks.
