i think you have come back home after few months because since last 1 month no major electrification development has happened at bhagalpur station as all focus was on jamalpur station electrification and tunnel electrification is still in progress which was major hurdle in past, escalators has just been set but stating will take too much time first shed will be made whose work has not even begun 1-2 month it will take.I live under 200m range of station and observe progress on daily basis.
