Plz carry a " Volini " or some other back pain relief solution if you are travelling by Ac chair car in this train or book 3A/2A classes which are now available. It has an official mps speed of 130 kmph but poor priority at NCR . So, always late . Don't think that it will be only a 17 hrs journey . Add 4 - 5 hrs extra & then estimate the journey time.
