Since examination still in progress. To get it reality(I mean papper to construction) it would require more time. Mean while Railway can build Narsapur to Kotipalli line at the earliest and opened for at least Goods traffic. So that railway can reduce the goods traffic in mainline. What ever the goods trains they want run in branchline Or No need to touch Rajahmundry and other impartant places in mainline. They can divert from samarlakorta - kotipalli- Narsapur. Yeah agree there is difference in KM to run but it won’t more than 80 KM. Really I don’t know the railway rules here. This is available alternative only that railway can consider.
