If you are comparing BGP/JYG GR with RNC GR, then you are wrong.
RNC GR and Nzm-Bdts GR are best GR of IR.
Priority of RNC GR is very high due to slot sharing with RNC Rajdhani. Dhamaka ko koi bhi train sirf apne hi slot pe kar skti hai in NCR be it RNC GR or be it SK. Out of slot SK bhi troll hoti hai NCR me
