Parbhani Hyderabad express never existed. Earlier also there was same pattern. Hyderabad - Parbhani - Nanded - Hyderabad passenger. Also this was rake sharing arrangement with Nanded Daund passenger. In ZBTT Hyderabad Parbhani pass was converted to 07563 Tandur Parbhani express for one month which was then renumbered as 07691 Tandur Parbhani express. There is no separate Hyderabad Parbhani and Tandur Parbhani. I dont have authentic press note, but as I travel between Parbhani to Nanded by this train frequently since few years I am aware of this.
