I have been to Dinajpur Railway Station in particular once. You can go directly from Rangpur CO Bazar to Dinajpur via Saidpur. I know a lot of the old junctions there. But I have forgotten a lot. I wish you success in your journey by train. I am happy to know that this station with a sick memory carries your beautiful memories. Of course, we will meet at various places including the railway station or bus station sometime, InshaAllah. I wish you success here.
