If Shiv Ganga Exp,Magadh Exp,Vaishali Exp all can overtake Poorvottar Sampark Kranti Exp,whereas each of the previous trains have numerous halts,where PSK is haltless in that stretch,then why cant PSK Exp overtake Mahananda Exp @ least @ Mokameh ???? ....Now Mahananda allowed to leave MKA too....poor PSK,has to halt unschedully @ MKA....It seems DyC's of Sonpur Division are totally uneducated & got their jobs by means of false impersonation.
