Bitter truth hai..but LKO public prefers LKO mail over AC express...just cuz of the name and the fame it posses..
High class train..high class security it has in each coach..also gvt officials and railway ones as well posses passes of LKO mail...they too travel with this..
Is ki wajah se it's gets huge priority and I remember last winter mein ek bar 12230 Overtook 12430 at Hardoi...
