Shatabdi caches are adjusted for Ganpati spl. It may not possible to CR do on continuous basis. DD has permited as spl only.
If CR do adjustment of coaches for Shatabdi for forever and if DD get clearance as a regular train than it is good, but what is the schedule of this both train?
Because 1) Jana-Shatabdi is running + Shatabdi will run that is also in a day up-down.
2)...
more... DD - CR has only one rack so that is also going to run in day up-down.
3) Even CR is thinking Rajya Rani Exp run on the basis of KOkankanya-Mandvi
