i guess 12735 is not so feasible considering the TAT required and also being a full AC ....if they can workout a way to change the return slot of 12736 (which is highly unlikely as if it is starting late from SBC...it will cause ripple effect on 22691 occupancy between sbc-sc also ) by making it start a little later than the current departure and make it work like a complete AC CC train with a fixed discount price like they did with other trains ..it can work
