Seems to be a pure LHB coach only. In the pics in the trains gallery, all the coaches are having the Y-shaped FIAT bogies that are seen only on LHB coaches. This particular coach looks like a coach from 04402 UHP-ANVT special, which has self-generating LHB coaches ( these have lesser MPS than pure LHB coaches, 105-120 kmph).
