can railway authorities divert blore rajdhani via tirupathy vijayawada and warangal as it is electrified and double line.and they can save time instead of running through sec and kurnool for atleast 3days a week.and train can go speed by this route.or it can be diverted via nandyal guntur and vijayawada, as gnt people have no direct trains bound to delhi.i think this would be better.
