I'm afraid, thats not a good news, atleast to me. If everything happens according to the notice, it will be common, just like any other special train of IR having Blue ICF coaches (i suppose IR will not provide LHB rake for it) & some electric loco. BR rake has its own uniqueness, afterall u don't regularly get to see a Bangladesh rake travelling in SER territory. Moreover, the Bangladesh Loco will run upto Darshana, so again, the uniqueness of this yearly special is lost.
