In a letter from Robert Penn Warren to Paul Engle, Robert says, ‘I shall arrive in Iowa City on the afternoon of Sunday, January 7 , on the Rocket.’ He is referring to the Rock Island Line, a railroad that went west from Chicago across Iowa. Though the line no longer runs, the old station still remains.
