No seat allocation for RNC NDLS one is done by SER. Actually seat allocation is done by the zone from where the train originates regardless of the zone of the train. So SER who has allocated seat for RNC NDLS one has given BKSC Gnwl whereas NR who has allocated seat for NDLS RNC one has given 4 seat to Bksc. You can find similar issue in Durgapur halt of Sdah Rajdhani also. For Sdah NDLS Rajdhani, ER has given highest number of seat to Durgapur among all the remote quotas whereas for NDLS Sdah Rajdhani, NR has given just 6 seat to Durgapur
