          A train passes through a railway junction where the poet is sitting alone as because the train passed through the junction a while ago and all the passengers have boarded the train.he is thinking in himself that all the people those who have boarded the train will go away from each other  after they reach their own destination.he also struggled for the noise noise of any bird or person or vehicle.And at the very end of the poem he also asked a question.
