A train derailment in Saginaw is the third in the area in the past year.
One locomotive derailed early Friday around midnight near Washington and Potter streets. Crews from Lake State Railway were on the scene Friday morning.
No injuries were reported. Mike Stickel of Lake State Railway says the derailment was "very minor" and the train remained upright.
The cause is under investigation. Derailments in March and August blocked roadway traffic in the area. Traffic wasn't blocked Friday.
