yes I agree....BBS rajdhani cant b compared with puru... but Puru soon after LHBfication was considered first to get a P7 at least in KGP-NDLS and vice versa whereas BBS rajdhani though received LHB rakes much earlier but still was running with P4 for a long time... though it's link was upgraded much later but it gets P7 end to end and regularly.... ye kahawat fit hai iske liye "Der aaye par durushth aaye"...
