Yes i think instead of waiting for all rakes to arrive , they have started it probably as a trial with whatver was available. I am guessing that over a period of time they will try and tweak some time table as there is slack both ways. In fact in the return journey some passenger associations of Odisha were highlighting how almost 2 hrs 30 min have been allocated between SBP-Jharsuguda just to cover 45/50 km. Similarly onward journey also has slack at some portions which can be reduced. Apart from this already some voices from Tata want this train to go to VSKP ( There is a significant Telugu population) and this train was the only option apart from the weekly Tata-VSKP ( not running as of now)
