Definition: A train wreck most often occurs as a result of an accident, such as when a train wheel jumps off a track in a derailment, or miscommunication, as when a moving train meets another train on the same track. The term is sometimes used metaphorically to describe a disaster that is foreseeable but unavoidable.
