Amazing!
Suggestions:
1) Remove Wardha and add Sewagram. (If you take it to wardha then the train has to be reversed to go to Nagpur.) If you still want to take it to Wardha, then add a reversal and atleast 15-20 min halt at Wardha.
then total reversals will be 8. :)
2)...
more... You may consider a halt at Pakur after RPH.
