The trains NS - GNT Pass. And GNT - DHNE Pass. have a continuous TT. They can be merged into a single train NS - DHNE Pass. and can be extended to GTL/KRNT. Then, LC will be at BZA.
I see many pax take tickets directly to NRT, VKN, MRK, NDL, DHNE for this train from KCC. This can be the case with the other stations before KCC.
In KCC, we have a raw announcement for the train as Narsapur - Dhone Passenger via Guntur..
