Did you know that the Ganga & Kaveri rivers are connected? ... by Mysore Varanasi Express - Vishwanath Joshi

Well, personally I don't see much benefit of having separate train between Krnt - tpty/hup. Instead, vizag/mumbai connectivity is essential at this moment as there is not even a single train.

FYI, Getting PM at Kurnool was one of the proposal mooted by ex MoSR and it didn't move because he resigned to protest new state formation otherwise it would have materialized. Though, there is some negligence about doubling/pitline via/at Kurnool but Kurnool has 3 dedicated trains to Hyderabad.

I am neither RM nor public representative to shift a train and as Vizag in another zone it may not an easy task to shift PM of a train.

I am not targeting single zone but my point is Guntur division is not giving enough importance to Nandyal which is second/third highest revenue generating stations in its division so why can't a single dedicated train b/w them. I mean despite road connectivity is pathetic. I'd wonder they are saying path constrains but I don't remember seeing GNT-NDL line in top congestion/HUN line.
