Pune Mumbai road is a expressway with & it is a comfort journy by buses as well, I have travelled two three times on this road. timing is may be the issue for the train to gent passengers Platforms sometimes engage & train will stand on outer for long time.
Where is Bhopal indore is not a good option by road & people will refer train if timing & fare is within there expectation. I think Janshatabdi is better option then DD on this route.
