160kmph line may be in shortest route and may not necessarily bee in longer route. They are plans to build separate corridors of 200kmh semi over ground like expressways and all options are being explored for South metro cities. It may take 2 yrs time for final decision regarding 160kmph on existing lines or 200kmph corridors.

SC-GTL speed upgradation is not planned as of now. KCG-DHNE will be upgraded to 160kmph

Nope. Doubling + upgradation to 160 kmph.
