(The point about the 70's was just to convey that there is no particular reason for which new trains should not be run on this route and that route priority is not a problem). The distance overhead is practically nothing. And one small advantage for this route is that it would run through the BZA yard, and trains can be dedicated to PF's 1-3 and need not wait at the outer for entering the station ( As we see for Circar/Seshadri and other trains now, which are mostly never held up at BZA outer). Anyways, here's hoping for good times ahead. :)
