According to ECoR RFs, this rake is actually the inaugural HS rake of NR.... NR sent only normal LHB rakes for many of the Humsafars' inauguration and later many of the trains got original HS rakes with all the facilities which were promised and anticipated... But unfortunately BBS-KJM/BBS-PNBE HS didn't get those rakes and finally the NR rake is being used with ECoR markings overwritten on the NR markings... One of the members of our ECoR whatsapp group recently traveled from Patna to BBS by this HS special train.. According to him the coaches are only the 3rd AC coaches of Rajdhani.. Nothing more than that..
