At least DDN, KLK, AII, ASR & KGM shatabdi should have only 1 hour TAT at these stations so that be made to depart from NDLS at appox 08:00 and arrive at 21:00 approx so that NDLS TAT can be maximised and there will be no issues of maintenance. This will ensure maximum occupancy of these shatabdis.
Because currently all shatabdis which are maintained at NDLS has departure before metro starts and arrival after metro closes.
