Yes this is the only reason, BP mail is NR train and that's why it runs with priority in NCR. For all other trains, it is their offence that they are NFR trains and they have to run in two great zones ( ECR.... the brand + NCR...... the bigger brand 😂😂)
Just for fun😂, but I think NFR should do tit for tat by not giving priority to BP mail in its zone for 1 week or 15 days 😂😂.
Par NFR ki niyat saaf hai, aisa hoga nahi
