My opinion on this train:
It should run between Ranchi and Jasidih with a connecting service to Dumka (timings of Dumka Jasidih passenger can be modified according to this train). Ranchi to Jasidih timings are good. In return journey, it should leave Jasidih at 1 PM and reach Ranchi by 8.30 PM.
Looking at seat availability, this train is not popular.
