For what it's worth, they have picked up the work between Mandsaur and Malhargarh. This seems promising because they are electrifying regions that are not contingent on imminent doubling (which is why there's no activity around Nimach, Nimbahera).
The whole region around CNA and COR is similar. There's no pending doubling/tripling work, and logically, that's where work should pick up next.
