It is a worst proposal,It will never happen in this century.We can't even Expect atleast Hasanparthi-Karimnagar Railway line also.The Only possible railway line which is going to be implemented on tracks is Kothapalli to Manoharabad,Apart from that none other projects in Telangana will not be on tracks.
Ramagundam to Manuguru may take 2 decades to complete,Because no good and efficient politicians are not there on that route.
If you take Peddapalli to Nizamabad there are 4 district Head Quarters in this Railway route and all are Municipalities and having good Road Connectivity.So think...
more... in a better way but not in a worst way
