It will still be the same problem even if there is a transfer to CR and if there is a new division formed. Aurangabad is still at the boundary of a zone, so originating traffic heading out of the zone will be very unlikely.
At the most, it might create room for extension of some Bombay-Manmad train to AWB, but originating trains from AWB, going towards Bhusaval via MMR will still be unlikely. They will get extended to NED to cover as many places as possible with a single train. In...
more... other words, if they need to run one train to AWB and one train to NED from MMR, they are more likely to run both till NED to cover as many places as possible with the existing trains. Unfortunately, that is how IR typically handles its operations.
Construction of AWB-Ahmednagar and AWB-Chalisgaon will pave the the way for more passing trains, but originating traffic will again be unlikely. If both routes are constructed, then they'll mostly use them for trains coming from Pune or some North bound trains from KOP/SBC.
That is not to say that AWB can never have originating trains. As I mentioned earlier, it can be developed as a terminal for North and East bound trains, with the trains taking the PAU-AK route or the Nanded-Warora route. Trains like NED-SRC and PAU-PNBE can be extended to Aurangabad. This just needs some political pressure.
With the right political support, AWB can be developed as the terminal for East, South and some North bound trains, while NED can continue as the terminal for West and some North bound trains. That way, the whole NED-AWB section is utilized to the maximum and gets connectivity to all parts of the country.
