Thanks a lot Siddharth!
1. Start by giving halts at PNME & KQR
2. I don't like the idea of have to reverse at a busy junction head like Patna.....rather I would still take the route that Maurya takes! Or take the route that SHM-GKP follows.
3. If you still insist on this route, then PNBE-PPTA speeds should be around 25-30 clicks
4....
more... From Patliputra upto Sonpur the average speed should be around 35-45 clicks.
5. Finally keep an average speed of around 50 after Sonpur, as the soil in and around Sonpur, Chapra, Siwan is rather loose, unfit for high speed action........
I have already flagged green, I hope you reflect on this suggestions....especially Point number 2!
