Yes. Mysore is not a dumpyard. But for trains coming from DMM and KPD, Mysore can be the option. For trains from ASK, extn to MYS is indeed waste as pax has to wait for extra 4 hrs. Hampi, Basava, Kacheguda Chennai all extensions are good for Mysore. If extended, even Udyan is beneficial but it ll be loss for Bangalore
