But Friday/Sunday slot is very much required between 2 big cities.... It can't be made to run for 6 days a week except for the most imp day! Anyway, if you want to keep this TT, make this train as 24 coach train and keep 6 coaches reserved for SC - NGP pax so that they don't lose out on a train. Those 6 coaches can be kept as SUR/GR - SC and SC - NGP.
