The concern is BKSC is a station with high demand but low credibility thanks to Adra division. Besides it won't be early but can happen. Remember how RNC GR was supposed to run via BKSC but it never did. RNC div overlook Bksc, DHN (Gmo), KQR,and ever crowded Gaya passengers. If that can happen surely this can as it will just say, we will just skip 1 station Bksc rest same with added haxaribagh. I hope it never happens but all would agree that it can as it has happened in past.
