In Southern Bihar one pending new rail line still not came in Picture i.e Aurangabad - Daudnagar - Arwal - paliganj - Bikram - Bihta. Instead of this rail line the end should not be in bihta rather in Danapur so that all impt towns can be connected as above said.
With that there is a ust 3rd rail line between Bihta to fatuha or Ara to fatuha.
