This UBL-MAS is running via GTL, RU and not via KPD. So, going to VLR does not arise. Again, for UBL to Vellore, you have tri-weekly PDY Chalukya (though at ghose hours, you will get town bus nos. 1 & 2 to vellore) apart from VSG-MAS weekly and UBL-MAS weekly all via YPR.
My point is that UBL-MAS via RU should be regularised as UBL-MS or further to CGL/VM/PDY with proper 14-15 hours journey time, as a ONT between Chennai-Hubli.
