Authorities are cleaning up after a Union Pacific coal train derailed in northeast Kansas. A child narrowly escaped injury after a fragment of rail landed inside the youngster’s bedroom.

Jefferson County authorities say 23 coal cars derailed just north of Grantville Monday night. Grantville is a few miles east of Topeka and 25 miles west of Lawrence.

Sheriff Jeff Herrig says no one was injured. But one house was damaged when a piece of rail landed inside. He says the piece of rail landed on the bottom bunk of a bunk bed, and a child was sleeping on the top bunk.

The cause of the derailment is under investigation.
