good to know this update.
Future of GY- Kalluru doubling progress depends on this year budget funds.
I was referring edduladoddi- Maddikera doubling by 2021 december as there are no major bridges...
more... and land acquisition problems , it may complete soon.
Biggest problem here is to double Guntakal and maddikera section which may require some kind of re-modelling at Guntakal station and if they can club linking PF 1,2 with rest of platforms then it will be good
