Not sure DD by pass will work. DD houses the crews for trains running through that section in many cases. If this train has a crew change there then it is unlikely.
a line between Pune-Nashik is proposed. that is what would actually save timing, but it will be years before the line is completed..
Agree to the reversal point. to avoid that karnataka has a different route, turning off from DD itself, but ends up not touching Pune.
