Has the rake composition been changed recently for this train as well as Kandari Express? At least the recent videos are telling that only. In stead of 17 coaches, it's now 18 coaches and the CC is not at the 2nd position from the loco. (Youtube video link copyright: Mr. Dipyaman Basu)
If it is not for temporary purpose (some one pls verify), I would request one of the admins to modify the rake composition of 12857/12858/18001/18002.
