experience kya bataye bhai bas 10 mint late pahuchi DBB. maja aaya journey kar k bas kamar ka haalat kharab hogaya. mind me bht se question ghum rhe hai ek ki kya DBB ko long distant train kavi milegi aur mil vi gayee toh maintainance kaise hogaya us train ka kyu ki DBB me sirf do track hai ek platform ka aur ek engine ko change krne k liye.
