When Suresh Prabhu was RM, rail services could not be improved to mao/vsg from SWR that means to say it is beyond control of SWR. UBL-vsg intercity, ubl-maq trains have been regularly demanded which haven't been introduced yet. Running services to different zones is always an issue and we know that because of Kalaburagi and MAQ. If major stations come under single zone it's much easier to co-ordinate and get prime slots of arrival and departure.
