From where did you get this information that BSK is most prioritized train in NER and NCR?
What about CNB-NDLS Shram Shakti Express, BJU-NDLS Vaishali Express,LJN-CSTM pushpak express, GKP-HSR Gorakhdham express.
I am not trying further to get more names here.
May there could be many more trains in such list
