I don't know..... i am not a local person of that area.... the person who travels daily can say what are the modes of transportation available there and from which time to which time between Bankura and Durgapur. But he comes Daily by the same way, so there maybe transport availability there or else how he travels daily, but that i don't know as i am not a local of Durgapur.
That travel is difficult that is why i said earlier that when SER will run a Intercity exp train from Adra to Howrah via Masagram route, these passengers who catch trains from Durgapur now will catch trains directly from Bankura, it will save time and money for them.
