In this poem, the poet describes the journey of the night mail train which travels at night and brings letters, cheques and postal orders for the people. It does not discriminate between the rich and the poor. It serves them all. It is very punctual and regular in its duty. It is never late. Its way is full of ups and downs but it does not get tired and continues its journey smoothly. It passes through cotton fields and hilly areas. It also passes by populated areas. The sheepdogs do not bark at it because they know that they cannot change its course. They continue to slumber. A jug is shaken in the bed room by the vibration of night mail when it moves along the houses.
