Bhau, there are many projects in IR which are still in pending. apart from this latest one, a Cable head car would b even more better than a light rail. Survey etc is done fr namesake bt when it comes to reality it takes ages. IR needs to work on light railway system.
On the flat surface its ok to run, but when it comes to such higher terrains, it needs a thorough research.
IF IR does the necessary works, then its ok.
