Not possible at least in near future!!! Nor needed.
Even if, it is, it's only weakly. Only symbolic As PM constituency BSB is.
Instead focus should be on timely running of 22408/07 which is daily on avg late by 3+ hours at ANVT. And speeding up of 12581/2 arrival time both end.
Expect 12559/60. All BSB trains junk sf exp.
