Yes lko mail , lko cdg, gomti, lko ndls ac exp can be shifted to ljn..but I don't think Lko NR is going to give their trains to NER LJN, also the fact that any train at LJN consumes not less than 30 min n originating trains stands for 1 hr or so... to balance the congestion both LJN n lko have to decide their operations mutually... Jo ki mumkin nhi lgta
