Sir, I wasn't asking for proof. I was just intrigued because few people would do such short trips, especially within the same city. But I guess it isn't that rare. Some guy here shared a boarding/deboarding image of Patna Rajdhani that starts from Rajendra Nagar Terminal and there were FOUR deboardings at PNBE itself. Which means folks booked in a Rajdhani just for traveling within the same city. I was surprised that Rajdhani trains even allowed for such short distance booking.
