A man walking on railroad tracks in Big Lake Township in the late afternoon on Monday was struck and killed by a northbound Northstar train.

The collision occurred north of the intersection at 192nd Av. NW and Zebulon St., west of Elk River. Sherburne County Sheriff officials said the railroad arms controlling the intersection were in the lowered position and the train stopped a short distance beyond the intersection after striking the man. The man has not yet been identified.

John Siqveland, a spokesman for Metro Transit, said no one was hurt on the train. Northstar passengers were put on other trains and buses to get to their destinations, he said, noting that some trains were delayed 45 minutes or more.

The Sherburne County Sheriff's Office and Metro Transit Police are investigating the collision.
