NR is not so much interested in giving a connection beyond NDLS for SCR...there have been many requests from SCR to run a train from SC beyond NDLS either to ASR/DDN ..however all the requests were rejected saying slot issues or some other issues..
first they showed YPR-SVDK as a train to use to go beyond NDLS and now TPTY-JAT...mostly case is closed and not expecting any trains beyond NDLS in the near future..unless NR puts the proposal nothing will happen in this case..
