Actually BDME station lies in the densely populated area , in the heart of the city , so expansion of the station is nearly impossible. Whereas the Deoghar station is in the outskirts of the city and will be definitely electrified some day . Moreover BDME station cant accomodate more than 10-12 coaches and thats the reason why the only exp train BDME RNC Intercity exp was shifted to Deoghar stn
