For Bhagalpur it won't be possibe
because Bhagalpur comes in the
direct route of Patna Via Allahabad Mugalsarai.
But for Katihar may be possible all is possible when
Railway Ministry have to look on it....

This trains goes via Lucknow Chhapra Samastipur
And the electrification of Barauni Katihar is in
under progress I'd watched the electrification work
this section has pole as well as wire above the tracks
but some work has to be done in Katihar Junction.
If this job is done may be it would be extend upto
Katihar Junction
