NFR's style is like this... previously North East Express too got LHBfied in the same manner when it's 4 rakes were LHBfied back to back on consecutive days of run from GHY... Consequently it's terminal was changed to KYQ as NGC Depot doesn't have the facilities for the maintenance of LHB Rakes..
P.S. So it's not the first Train to get LHBfied in this manner...:)
