This train lost the priority it once had. Neither NR nor RB is interested in this train anymore.
BTW your suggestion is very good. I also had the same thought, and I just tweeted it to RM and PMO cz i have 0 hope from Railway Board and NR,WCR officials. So i directly send it to RM hoping that he may consider this under Mission Raftaar on which he is focusing currently so that he may instruct RB about it.
