who were the rajvir and pranjo ? where were they going by train ? describe the scenery outside the train?

Rajvir and Pranjol were two friends. Rajvir was a young Sikh boy, who was travelling with Pranjol, to spend the holidays in a tea estate of Assam. Pranjol's father was the manager of a tea estate. When Rajvir woke up he saw the lush green paddy fields had long disappeared. In its place there was the lovely tea gardens gently sloping own. The change in scenery was almost breath taking.
