SWR UBL is the option where Karnataka can get more trains. It definitely has the capacity. It can be connected to many places. SWR this time even asked for Delhi, Mangaluru connectivity. May be next time it may get. If you see, UBL-MAO section is also under utilized coz there are constraint in running trains in Braganza ghat.It requires 2-3 engines at the rear end of the train for the proper movement of the train. That is why weeklies only run in this section. SBC-UBL is not doubled, still in progress. SUR-GDG section provides good connectivity, but there is speed limitation in this section, due to which train crawls in this section.
