It would be better to swap this slot with CBE LTT. CBE LTT can depart at 0600 to reach SBC by 1300 and further reach LTT by 1000. LTT CBE can leave by 1700 to reach SBC by 1400 and CBE by 2100.
Uday can start from CBE by 0900 and return as night train in LTT slot. Alternatively uday can become Humsafar
