Reason experts SWR's version would be: "Udyan is CR rake and ERS-SBC SF is SR rake. We need lot of coordination."
KSRTC will not agree to such a proposal.
My suggestion would be: Extend BIDR-YPR which is a SWR train to MYS during Dasara and see the response. Atleast this part of Karnataka get a direct train to MYS.
