Bittu Ji... kindly provide some photos n videos taken by you from Gaya and adjoining stations of the Grand Chord Route.... even I have taken a video from my seat window while traveling by 12357 Durgiana Exp way back in Dec, 2012 but it was a night time video.... at present there is not a single daily superfast that runs between Calcutta and Amritsar via Dhanbad - Gaya Route :-(
