A train accident or train wreck is a type of disaster involving two or more trains. Train wrecks often occur as a result of miscommunication, as when a moving train meets another train on the same track, when the wheels of train come off the track or when a boiler explosion occurs. Train accidents have often been widely covered in popular media and in folklore.
A head-on collision between two trains is colloquially called a "cornfield meet" in the United States.[1]
