Please note:-

more... to run combined with 3467 BGP PNBE NDLS Vikramshila Link Express (now independent as 12367 BGP NDLS Vikramshila Express) from PNBE to NDLS at that time (I'll share the TT of 3467 Vikramshila later)
4. Zone is unknown but given as Eastern since PNBE fell under Eastern Zone then.
