I was thinking whether it was possible to achieve 180 kmph speed of rrts on regular 5'6 broad gauge.
RRTS is good but it uses smaller gauge and we are ending up using three different gauge throughout the country. A RRTS arrangement on regular gauge would do wonders for our railway.
I am talking about fully ripping out the old tracks and use Concrete ballast base on busy routes.

This will serve two purpose 1)Facilitate high speed passenger trains 2)Facilitate Express train on the same track.
