Engine No. 19 is the pride of Tom's heart, but as he is unable to lot drink alone he is discharged. Feeling that he no longer can obtain employment, he leaves home, and soon starts on the downward path. He is about to enter a bar-room when the face of his mother haunts him. He puts aside the temptation and decides to return home. A bandit tries to overpower the engineer on the Limited, but is captured by Tom who creeps over the top of the car. He refuses a reward, but states that if he had his position back he would prove himself a man. He returns to his mother and sweetheart who have read of his heroism and are pleased to see him.
