No updates on 16331/16332. I think LHB coaches might be needed for that train ( one rake required) since it has just 1 hr turnaround time at CSMT. For 16381/16382 there was some news that maybe mid Feb something might happen. Not sure about it. LHB coaches required for that as well. Once Mangala rakes are done then they might start with conversion of 16381/16382. Also there is some work on pit lines being done at NCJ so SR is not in any hurry to introduce Jayanti immediately
