But then, Amravati has to originate from old complex of HWH or from Sealdah. Anyways, 18046 can have rsa with old rsa of gitanjali, 18049 with 18045
And 12860 with 18615. Easily managed. 2 rakes will be saved, and load from SRC will be reduced.
Even 12837 Hwh-puri exp can have rsa with 12860 or 18045.
