Yes, JS enjoy the same priority as Shatabdi Exp. JS is a boon to common people who cannot afford AC CC in shatabdi/Janshatabdi. Very nice concept and all thanks to Nitish Ji , he gave this gift without compromising the category of train i.e., Shatabdi. If they could include catering (optional) in the fare it will be great in long run. :)
Miss the old livery though of Shtb/JShtb (*_*)
