I doubt it will lose it's JN status so soon!
1. As far as I know ECR, it would not do anything on it's own unless a catastrophe happens. Then the actual blamegame would start. Maybe then alternative steps might be taken or I don't see ECR actually doing something unless it gets severe pressure from the MOR or RB. And ER doesn't any longer have the bargaining power it once had maybe an ER/SER persuassion may force ECR to act on the issue! Secondly a new line connection between DHN & GRD is in talks so even if DHN loses it's JN status now, it is likely to reclaim in the near future :)
2....
more... Secondly Lets not talk about Bihar, Jharkhand and Bengal here as IRI is neither a place to settle interstate debates nor is it a site to discuss Corruption indexes and economic condition of cities!
Lets stick to rail talk only :)
