The only information which I got from RCF (Rail Coach Factory) Kapurthala is that, a set of brand new LHB CC coaches have been made for ECoR and that is obviously for PURI-HWH Shatabdi Express. In addition to that, railfan Mr. Siddharth Singh Rajput (from Bhubaneswar) has mentioned in facebook that NR has already transferred that rake to ECoR and it is standing at Khurda Road. Clearly, it will not take a long time for Shatabdi to get LHB coaches. But when, that I don't know yet. Some railfans are predicting it to be in coming January.
