Needed demand. The point now in discussion is to arrange the rake for this train and build an RSA with another MEMU to bring rake to KGP for maintainance. Once RSA or rake arrangement gets final this MEMU will start. Proposal will be sent to RB soon for Approval but before sending it discussion on RSA needs to be complete as getting new MEMU rake for this train now is little difficult and time taking so better if any RSA can be worked out with any other MEMU then approval and start will be faster that is the point.
