EUDORA, Kan. (AP) — Authorities in eastern Kansas say two 16-year-old boys have been released from the hospital after being struck by a train on a railroad bridge.

Douglas County Sheriff’s Office spokesman Lt. Steve Lewis tells The Lawrence Journal-World  on Tuesday that both teens have been discharged but one will have to return for additional surgery on a broken bone.

Lewis says the boys from Lawrence and Eudora were hanging out on the bridge Nov. 1 and couldn’t move quickly enough to avoid the train. Their identities haven’t been released.

Deputies are investigating the collision.
