I am very much agreed with you regarding NJP & PURI Shatabdi and if I am not incorrect, these Shatabdis will be stopped in near future as the ROU & PNBE Shatabdi stopped. My proposal is to run Double Decker Sleeper coaches for overnight journey in both the routes. Will you let me know how the seats are in the DDs ? Whether the coaches are AC or not ? The details regarding the Double Decker coaches (preferably with a photograph). As you are well aware that since I lived in a remote place of Sikkim, it will not be possible for me to see the DD coaches in near future.
