Sorry, I'm living in Eastwards of this station i.e near WJR and have appropriate routes over there. But, one thing which for sure is, Kaveri Exp mostly doesn't run on time. Hence, when you arrive at KPD, it should be convenient for you wait for 57404 KPD-TPTY DEMU, rather than Say you arrive 5am max, catch a Public transport, reach New bus stand, then catch Tirupati bus which won't make that convenient journey...
