   Usage: Train, Cars. At one time "train" meaning railroad
          train was also referred to in the U. S. by the phrase
          "the cars". In the 1913 dictionary the usage was
          described thus: "Train is the word universally used in
          England with reference to railroad traveling; as, I
          came in the morning train. In the United States, the
          phrase the cars has been extensively introduced in the
          room of train; as, the cars are late; I came in the
          cars. The English expression is obviously more
          appropriate, and is prevailing more and more among
          Americans, to the exclusion of the cars."
